Video Transcript for Derale Series 8000 Transmission Cooler Review

Speaker 1: Today we'll be having a look at the Derale 8000 Series line of plate-fin transmission coolers. Here's what our transmission cooler looks like installed. Now, the reason you're gonna want an auxiliary transmission cooler such as this one on your vehicle is quite simple. Heat is the enemy of transmissions. It is the number one cause of premature failure on your transmission. By reducing the temperature of the fluid inside your transmission, you will extend the life of it, and also have added cooling abilities.

The colder the transmission fluid is, the more heat it can actually absorb. Plus, we are expanding the cooling capacity of the system by having additional room for more fluid, which, will also help reduce the temperature.Now, you may ask, "How is this important to me because my vehicle already has a transmission cooler build inside the radiator" Well, it's quite simple. If you we're ever planning on doing aggressive driving, or towing a trailer, towing a trailer causes additional wear and tear on your transmission, and causes increased fluid temperature. By cooling the temperature down further, you are making it easier on your vehicle in order to tow that extra weight. Now, how this works being installing in addition to the factory cooler inside the radiator, the fluid will leave the factory transmission cooler from the radiator, go inside of our auxiliary cooler here that we installed, get cooled down even further, and then go back into the return line that goes into your transmission.

So, you're adding additional cooling capacity, and a secondary cooler by having this aftermarket cooler installed.Now, for a few measurements to better assist you in choosing if this cooler's gonna work for your vehicle. At its widest point, it's 11" wide. From the very top to the very bottom, it's 7 1/4" tall, and it is 7/8 of an inch thick. Now, one thing our customers have noticed, when they're installing this cooler on a vehicle, they have noticed when they're installing it inline with the factory transmission cooler, that they have needed additional hose. Now, we do have additional hose available on our website.

Now, the 8000 Series of Derale transmission coolers are plate-fin design, and the plate-fin design increase surface area. The more surface area that we have, the more cooling capacity that we have. The more of your fluid you can spread out over a larger distance, the more it can get cooled down to reduce the temperature of your transmission.This cooler also features turbulator technology to help agitate the fluid passing through it. To help with heat transfer, but also to help prevent any drop in fluid pressure. Our transmission operates off fluid pressure, so if it falls below a certain amount, it may not shift gears properly.

By maintaining our fluid pressure, our transmission will shift gears properly, and work as it's designed. This cooler has an aluminum construction, so we don't need to worry about it corroding or rusting out over the course of time. It also has a nice gloss black finish, so it'll be easily concealed behind the grill of your vehicle, and it won't be visible are you're looking at the front of your car.And that completes our look at the Derale 8000 Series line of plate-fin transmission coolers.

Installed the product today. My installation is pretty unique on the Jeep Liberty CRD. This vehicle has a pusher fan in front of the stack of heat exchangers (Condenser/Trans cooler, intercooler, radiator), so the "zip tie" installation is not an option. Also, the stock trans cooler, which is the bottom 1/4 of the A/C condenser, has a different type of fitting on it. Product seems to work as intended. Hoses were a bit hard to get onto the barbs, even with a little transmission fluid as a lubricant. 47086

Fun to install but if you follow the video it goes really smoothly. This was the number 1 recommended cooler for my 2012 Honda Odyssey Touring so I went ahead and got it. Before installing it I hooked my scanner to my van and drove 2 straight hours in the city and on the high way, transmission fluid temperatures would reach 195 at times. After installing it I tested the temperatures under normal driving and under towing. Under normal driving, after 2 hours the transmission fluid never got over 170. It took almost 3 hours before the transmission fluid reached 185. The van was already nice and warm when I decided to test towing so I'm not sure how long it took to get up to temperature but I can say after 45 minutes of driving through the Saura Town mountains (Hanging Rock, NC), the transmission temperature never went above 190. I would give 5 stars but the provided hose was not the correct ID and I could not get it to fit properly so I had to go buy more hose. 444073

This transmission cooler fit perfectly behind my grill. I mounted it on brackets in lieu of a direct mount on the radiator. I’m glad you recommended the GM adaptor hose fitting as my application would not work with the Insta-Dapt which was not compatible. Works great towing my 4,000# trailer in this Florida heat. 524895

2005 Honda Odyssey

I decided to install the Derale 8000 on my 2005 Honda Odyssey with 57,500 miles as an investment in hopes to prolong the life of vehicle. The Derale 8000 series came with complete with all the parts needed for my installation. I had zero trips to the auto parts store. I'm not a mechanic but the installation was fairly easy. The videos provided by etrailer was extremely helpful and gave me confidence to do the install. The hose, provided, fits perfectly into the factory Honda hose outlet from the radiator. Also, as mentioned by other reviewers, installing the hose is a difficult even with transmission fluid to lubricate. However, I had a hard time trying to secure the cooler, due to the tight space between the condenser and radiator. A long cutting pliers/scissor would help and a lots of patience. Install with confidence! Thanks Etrailer for the awesome instructional videos! 391814

2003 dodge caravan sport 3.3l. 110kmiles Where to start... Well it's okay. Fwiw, it's small and made of metal. I didn't know it but there was a trans cooler already installed in my vehicle, and it is aluminum much much better at dissipating heat. I read every review from here to there, watched all the videos. The common theme (sales pitch) is you can't cool your trans fluid enough. I will agree with that statement, but I also believe too much of a good thing is no good. When mounted the way recommended this unit sits directly in front of the air condenser/oem trans cooler/ radiator. It blocks some of the air that is passing through. **I did a before and after check using a infrared heat gun on the lines. It was a few degrees cooler under normal operating conditions, idle for a few minutes. I don't know what the difference is under heavy loads but imagine the difference may grow to as much as 10-15 degrees or so. Somebody in the laboratory (engineers) has this info, but they won't post it for obvious reasons. Not much of a difference at all, but if you are concerned about protecting your transmission, then this may help you to sleep a little better. I'm giving this three stars because while it will help me to sleep a little better it is fairly cheap in materials. The fasteners are plastic zip ties, (PLASTIC). If you've ever used zip ties you know they don't last long. I didn't have to use much hose and only used it on one side, the other end (existing line) was long enough so that worked out fine. I think if you have a newer vehicle this is the route to go as far as bolt on and go there's nothing i found easier than this. However, at over 100k miles, it was not fun at all. My fasteners were stubborn and I could not get behind the a/c condensor to secure the fasteners behind without disconnecting the a/c lines. I didn't have a problem with removing the a/c lines because after over 10 years the a/c was weak and needed to be serviced. This totally bit me in the rear. After assembly, I thought I could simply head over to the a/c shop for a recharge at a fair price. They got half way through and during the recharge mode their machine failed and it could not be completed. After doing extensive research (many many hours) into a/c service, repair and TMI (too much information) overload. My options were either to nickle and dime repair my a/c system or buy a complete a/c kit, spend an entire back breaking weekend installing it, then paying the shop to charge it, looking at upwards of 5 benjamins or more if I did it myself. I settled on an over the counter a/c recharge kit. It worked fine, but that took many hours of research to determine whether or not it was working correctly. In short, if you have a newer vehicle with less than 100k miles or so I'd recommend it only if you are occasionally towing upward of 75% of your vehicle tow capacity. If your towing weight is less, and you are not towing very often then your vehicle already has a cooler in it that should be more than sufficient. If you are towing beyond 75% of your vehicle capacity and doing it frequently, IMO I believe your best option is to get a tow vehicle with a higher rated tow capacity to begin with. For vehicles over 100K miles, it's your call. I did it, but I did it because over the course of 10+years my vehicle rarely carried much weight in it at all and it was always serviced regularly except -as mentioned - the a/c. I still think my transmission has a lot of life in it, and for what I paid on this D13503 in addition to suspension upgrades, I least I know that I did what I could as far as preventive maintenance. One final note, do not remove any more parts/grilles, nuts and bolts, wires, lines on your vehicle than absolutely necessary. Make it as simple on yourself as you can. Some of these videos have you cutting lines, adding compression fittings, ( I didn't need any) removing wiring harnesses, etc, etc,,. Look at the big picture. Every install is a little bit different. And if you decide to go with this transmission cooler it should drop right in and you can carry on with whatever else is more important, family, friends, life, etc.. Thank you very much for reading my review, and may you have a wonderful day. Olajoe 93170

2013 Chevrolet Tahoe

I ordered a transmission cooler for my '09 Tahoe that, even with the small cooler for the towing package, just could not handle the California/Oregon mountains. I had my trusted mechanic install it (he has much greater expertise than I). I've just returned from an identical trip over those same mountains. What a difference! Instead of topping out at 230 degrees (dangerous), I topped out at 183, only 13 degrees from normal operating temp. I ordered the cooler and installation hardware. It's been awesome not to have to worry anymore about transmission burn out hauling my trailer that is 25% BELOW advertised towing capacity of this vehicle. Kudos to etrailer for offering such great products! 302744

Excellent quality and build. I installed this in a 2003 Chevrolet Avalanche. I wanted a factory look installation so I mounted the bottom of the cooler in the factory bracket located mid way and made a bracket to mount the top of the cooler. I mounted it with the hoses downward so they will not be visible from the outside of the car. See pics for details on the brackets and mounting. 176500

Hardest part of the installation was confirming which of the lines was the hot and which was cold. After that, installation on my 2005 Pilot was easy. Just follow directions or find a YouTube video. Tranny coolers are a must if you're planning on taxing the transmission by hauling/pulling or doing lots of hill climbing with a load in the truck/SUV. Shipping was super fast and customer service follow up on my order was great. I will absolutely buy all my trailer stuff from these guys. 291142

2010 Jeep Liberty

Thanks for shipping so fast. the response time was impressive! Below is a picture of the install of my Derale trans cooler (13503) installed in my 2010 Jeep Liberty. I did not install with the inlet/outlet on the bottom due to thinking that with a plate and fin type cooler air might get trapped in other end. I mounted it horizontal and put the inlet flow on the bottom to assure that any air gets purged. Odd thing about this trans is that there is a bypass valve on the lines that is thermally operated. The flow to the coolers is bypassed until a specific oil temp is reached. Then flow is allowed to go to the cooler(s). This is done because the trans cooler is completely independent of the radiator. There is no thermal exchange between the trans fluid and the engine coolant. With the transmission fluid bypass valve in operation it is not possible to reduce trans temp below a preset level (or nearer ambient temp) because the thermostat valve simply turns off flow to the cooler(s). In a conventional setup the coolant flows all the time and there is no by-pass. Trans fluid is kept from dropping in temp by the engine coolant which will actually put heat into the trans coolant if the engine coolant is warmer. Chrysler has no thermal exchange with the engine coolant so they thermostatically control flow to keep the trans from operation at a too low temp. In short, in my vehicle I can’t reduce the trans temp below the thermostat setting, But I can assure that the temp of the trans can never be too hot. I also mounted the trans cooler on brackets I made. I was uncomfortable pushing the rods thru the radiator and the air conditioning and factory trans cooler. The added mass of the Derale trans cooler may have been a little too much clamped onto the radiator. I tapped into the original hose with a 3/8 double barb fitting and double clamped all connections. Also below is a exploded parts view showing the by pass valve on the trans lines which directs trans fluid back to the trans and by passes the cooler(s) until the trans gets to a specific temp. It is item #3. 97702

Nice discussion John, thx. Did you have over heating problems prior to cooler install. I have a 2011 Liberty that overheats any time I use it off road on hills in the summer....the Jeep dealer told me that they all do this...I wonder if its actually the bypass thermostat?

Hi Don, My Jeep has never overheated either engine or trans. I have never heard of them being prone to overheating either. If you suspect the inline thermostat on the coolant line I think that would be easy to check simply by feeling the lines and seeing if the line is returning hot trans fluid without going up front to shed some heat. I added the cooler because I put a trailer hitch on and just wanted to make sure that the trans would stay in the proper operating temp range. Are there a lot of bugsdebris in the trans or engine radiators? Is the thermostat cycling properly? Any pinched hoses? If the engine coolant is too hot it may be a pinched hose. Check the temp of the inlet hose versus outlet hose while the engine is running. If the return line is at the same temp as the outlet hose the radiator is not shedding the heat adequately. Cooling problems can be a little tricky but a little detective work can usually solve it.

It was a pretty straight forward installation. I did have to remove the battery and tray as the factory spring hose clamps were positioned such that I could only get at them from the top, couldn't squeeze the clamps from a below angle. Thankfully I watched their video before ordering to see I needed another length of hose to finish the install. Took about 3 hours and seems to work well. 568120

2010 Honda Odyssey

The D13503 transmission cooler was a fairly straightforward DIY installation on a 2010 (3rd gen) Honda Odyssey. Watch a video or two on etrailer.com and you should be able to figure everything out. Two issues came up. First, it is not trivial to get the hose pushed securely onto the nipples of the cooler or the vehicle. Readers should thoroughly lube the inside of the hose and the outside of the nipple. (I suppose a tight fit is good, just be prepared to apply force and be patient!) Second -- and this is why the product only gets 4 stars from me -- the head of one of the plastic mounting rods broke off. No extras are supplied, so I figured out a zip-tie solution. It leaves me nervous about the strength of the remaining three, but the installation seems secure for now. Potential DIYers should also note that you are likely to break some of the body panel retainers (aka "clips") during disassembly of your vehicle's front end. (Not surprising on my 95,000 mile van; they were brittle.) Be prepared and locate a source for replacements ahead of time. Overall, this product seems well-designed, is offered at a great price from etrailer, and has the potential to lengthen the life of your transmission even when not towing. 348570

Installed this in a 2005 Nissan Pathfinder. Fit is excellent. I wanted to remove the factory radiator connection as this is a common point of failure allowing coolent to enter the ATF. This is plumbed from the transmission to the factory cooler, then to this new cooler, then back to the transmission. The only thing extra I had to buy was a 3/8 double barb to connect to an existing hose. This cooler adds about half a quart of ATF to the system. I can't speak for any temp drops as I don't have a temp gauge installed yet. 101344

Good product easy install! had to order extra 5 feet hose to fit my 2012 Sienna. I bought it for towing my RV without damaging my transmission. Don't have any info if it really helps lowering my trans temperature but pretty confident about it. 528992

The cooler was exactly as described. The best part was the instructional videos showing 2 different installs on Honda Odysseys. They each installed it in slightly different ways so I was able to use both videos to get the job done right. I wouldn't have felt confident in doing this job myself without etrailer's assurance that I was getting the right part. 443108

2007 Chevrolet Silverado

I have a 2007 Silverado Classic w/ 4.8L and was somewhat nervous about buying the tranny cooler because I have never done this before, but honestly, it's pretty self-explanatory. I bought the 8000 series I also used GM adapter D13035 and it fit easily in the "out" position of the radiator. I placed the cooler in the very front of the oil cooler so that it would get 100% air. However, because I did not want the ties to go through the oil cooler and then the radiator, there is a bottom bracket that goes across <--------------> the oil cooler and I cut slits into it and made holding bracket for the trans. cooler so now it is about an inch in front of the oil cooler. This will allow maximum cooling because air can circulate all the way around the cooler. I'll post some pics when I can. -Art P.s. Had to buy about 3 more feet of hose, but not too bad of an install for someone who hasn't done this before. 31532


Comments
I am installing this on a 2007 Silverado, new body style, V6, 4.3L . I assume the trnasmission return metal line will have to be cut and the rubber line coming from the cooler will fasten to it? Is there an adapter for this or just a standard hose crimp?
-- comment by: Derek - 02/10/2014

You will connect the new cooler input to the OEM cooler output using an adapter, part D13035. From there output hose on the new cooler will fit over the barb on the metal OEM return line and use a hose clap to secure. We have a video of this kit being installed on a 2011 Suburban, the install will be very similar on your Silverado.

2005 Chevrolet Avalanche

Just installed this on my 2005 Avalanche (since I'll be towing a larger travel trailer now), after seeing the how-to video on this site (relating to the same product). Overall the installation went very well, and I highly recommend this product. While my Avalanche had the factory-installed towing option, it did not provide an external transmission cooler and instead utilized a cooler built into the radiator tank (better than nothing, but an external cooler is best). If you're installing on a 2005-era Chevy 1/2 ton, do yourself a favor and order the D13002 Mounting Kit and the D13035 Radiator Adapter fitting; and while you're at it I recommend getting another 3' or so of 5/16" transmission cooler hose. The first two items make it a no-brainer to install the cooler, and while the cooler hose supplied with this cooler is decent, it's just not long enough to supply the hose lengths required to connect to the radiator and the existing line going back to the trans. Of course, I mounted my cooler in the center of the rad on the factory "A" frame (in front of the rad), if you somehow mount the cooler more to the passenger side then the supplied hose might be long enough. I ended up using two of the supplied self-tapping screws, but needed to obtain four bolt/washer/locknut combos to mount the brackets to the cooler's mounting holes. The cooler comes with four pads and plastic straps to mount it against the radiator, but no one I talked to likes those as they tend to break over time. Better off mounting it properly :-) Since I don't have a transmission temp gauge I can't tell exactly how much cooler it's operating, but a trans cooler like this is pretty much a requirement for any substantial trailer weight. 153766

this product is of good quality and a good size to make a big difference on the cooling of the transmission, so much that when its spring winter or fall, when i'm just driving around town the engine wont get to operating temperature until i drive for about 30 min. It's an easy fix to just use a piece of cardboard over the transmission coolers when its cold out and your not towing. Then the temp comes up as usual. When towing just make sure to keep the bugs out of your rad and coolers. Towed my trailer through the mountains where my truck over heated last year and had no problems this year. truck is a 2012 ecoboost 3.5l f150. Needed a few fitting but the local farm supply store had them, i hooked it up in series behind of my stock cooler, the fluid goes from the rad to this cooler then the stock cooler. 568743

Fabulous. For a 2002 Odyssey don't remove factory fittings from RADIATOR. Remove hoses from steel tubes that come off the radiator and use a double male fitting from the hardware store for the return hose. To make life really easy, download a copy of Honda's installation for Factory Cooler to figure exactly where the return lines are. Rip off the bumper. Get er done. 1 hr. The whole car drives different. Smoother. Quieter. 39178

For your Pilot I recommend using part # D13503 which is 11" wide x 8-3/4" tall x 7/8" deep and for your Avalanche I recommend using part # D13504 which is slightly larger at 11" wide x 12" tall x 7/8" deep. Either of these options will work well for you and provide your vehicle with adequate transmission fluid cooling. However, in order to install a...

  • Installing A Transmission Cooler On A 2017 Honda Pilot
    I called my contact at Derale Performance and they stated that they are not aware of any required software updates though they do recommend adding an additional 5-10 oz. of transmission fluid to the system. To be certain, I recommend asking your local Honda dealer if firmware adjustments are necessary. For a transmission cooler that will work with your 2017 Honda Pilot, I recommending using Derale Series 8000 Plate-Fin Transmission Cooler Kit w/Barb Inlets part # D13503 as this is the...

  • Derale Remote-Positioned Transmission Cooler for 2012 Chevrolet Suburban 5.3L 4WD
    A supplementary transmission cooler is an excellent addition to almost any towing vehicle and we have options for your 2012 Chevrolet Suburban 5.3L. If you have the specific transmission model 4L80E in your Suburban you can use pan-style cooler # D14207 from Derale. The benefit of a bolt-on pan cooler is that you actually add fluid capacity to your transmission system. This item does not simply radiate away heat like # D13503; it both radiates heat away and cools additionally by letting...

  • What is Needed to Tow a Trailer With a 2008 Honda Odyssey?
    So far you have Draw-Tite Hitch # 75270, a 4-way harness # 118438, brake controller install kit # ETBC7L, Curt Echo brake controller # C51180 and transmission cooler # D13503. This is a very good start in terms of what you need to tow with your 2008 Honda Odyssey. However, you were correct that you will need a ball mount, hitch ball and pin and clip. If you are going to be towing, I recommend checking out Ball Mount Kit # 989900, which may fulfill your towing needs in one tidy package;...

  • Transmission Cooler for 2018 Ford F150 SuperCrew XLT - 4wd 5.0L V8 Without Factory Tow Package
    Most aftermarket transmission coolers we carry are going to fit a wide variety of vehicles, and for someone who is mechanically inclined they're a relatively easy installation. For maximum cooling, bigger is always better and plate fin coolers do a better job of dispersing heat than a tube fin cooler. For those reasons I recommend going with the Derale # D13504 which is an 11" wide x 12" tall x 7/8" deep plate fin cooler. This is a standard mount cooler that can be mounted in 3 different...

  • Differences Between Derale Transmission Cooler Derale D13503, D13504, and D13502
    The differerence between the three coolers you mentioned is the size overall. The # D13503 measures 11" Wide x 8-3/4" tall x 7/8" deep. The part # D13502 measures 11" Wide x 7-1/4" tall x 7/8" deep (slightly shorter) and the part # D13504 measures 11" Wide x 12" tall x 7/8" deep. We recommend fitting the biggest cooler you can fit in the available space in front of the radiator.

  • Towing Setup for a 2017 Subaru Outback Wagon
    According to my research, your 2017 Subaru Outback Wagon has a max towing capacity of 1,000 lbs if the trailer does not have brakes or 2,700 lbs if the trailer does have brakes. You can improve the towing performance/efficiency of your vehicle with a transmission cooler like part # D13503 but you cannot increase it's capacity. The tongue weight rating of 200 lbs is correct but I cannot recommend you go over this. In order to set your Outback up for towing a trailer with brakes you will...

  • Recommended Transmission Cooler for 2009 Chevy Suburban with 5.3L Engine
    For your 2009 Chevrolet Suburban with a 5.3L engine, you can still install any transmission cooler that will fit in the available space between the grille and A/C condenser. Transmission coolers are not vehicle-specific, so any cooler for which you have the proper mounting space can be installed as long as the transmission has external lines to allow you to tap into the system. I recommend taking a look at the Derale Transmission Cooler # D13503. This is an excellent and efficient heat...

  • Transmission Cooler Recommendation for 2017 Honda Odyssey
    For your 2017 Honda Odyssey the transmission cooler I recommend is the Derale part # D13503 which is large enough and efficient enough to do a great job prolonging the life of your transmission. It measures 11" Wide x 8-3/4" tall x 7/8" deep and we found that it works great on Odysseys like yours. The picture I attached shows it mounted on a 2014 Odyssey and the video I attached shows it installed on a 2013 model which will walk you through the same process on your 2017.

  • How Much Transmission Fluid Will the Derale Series 8000 Plate-Fin Transmission Cooler # D13503 Need
    The Derale Series 8000 Plate-Fin Transmission Cooler Kit # D13503 for your 2016 Honda Pilot EX-L will hold about 5-1/2 to 6 ounces of transmission fluid. This will vary not only by the length of hose you use, like you mentioned, but also how much fluid is lost during the installation. Just be sure you have a little over 6 ounces and you should be good to go. Attached is an installation video of this cooler on a 2016 Pilot that you can reference.

  • Should a Transmission Cooler be Installed on a 2016 Honda Odyssey for Towing Just One Time
    A transmission cooler is recommended equipment for towing with a 2016 Honda Odyssey. Given the weight of the trailer it may not be 100 percent necessary but a transmission cooler has benefits beyond just towing. Factory coolers are adequate at best so a transmission cooler will help keep the fluid cooler which in turn will help to get the most life out of your transmission even in daily driving situations. The most popular cooler for your Odyssey is # D13503. I have linked a video showing...

  • Compatibility of Derale Transmission Cooler with 2012 VW Routan SE
    Transmission coolers are not actually vehicle-specific so any given cooler can be installed in many different vehicles so long as there is enough space for the cooler itself and for the fluid hoses, which you do not want to force to make sharp bends and turns (which can interfere with fluid flow). Also, your transmission must have external lines that allow you to tap into that system to insert the cooler. There are two lines, send and return, and the one you want to tap into for a supplemental...

    When we installed the Derale transmission cooler part # D13503 on a very similar 2013 Dodge Grand Caravan we found that we had to use the adapter part # D13035 that you mentioned.

  • Is a Transmission Cooler Needed to Tow Trailers with 2007 Honda Pilot
    An aftermarket transmission cooler is not required for you to tow a trailer with your Honda Pilot. However, it may be a good idea and it will certainly help to extend the life of your transmission, especially if you plan on towing often with your Pilot. The majority of transmission failures are a direct result of overheating and most factory cooling systems are at best adequate, and not necessarily designed to keep fluid at the appropriate temperature during towing conditions. While...

  • Transmission Cooler Recommendation for 2010 GMC Yukon XL
    Plate-fin coolers are the preferred transmission cooler style as they are much more efficient than the tube fin coolers. They are also much more durable as the tube fin style has fins that are easily bent. What I would recommend you do is keep your current cooler and then install a supplemental cooler like part # D13503 downstream of it so that you can maximize your cooling efficiency. You will want the fitting part # D13035 to make the install of the cooler easier. This prevents you...

  • Where to Install Transmission Cooler on a 2006 Toyota Sienna
    I can help you with installing your transmission cooler, # D13503. On the majority of vehicles the ideal location to install your transmission cooler would be to mount the cooler in front of your vehicle's radiator (position A in the picture). At this location, the cooler will be able to work more efficiently than installed behind the A/C condenser or behind the radiator. However, sometimes there will be a clearance issue and the cooler will have to installed in the other locations...

    Transmission coolers such as # D13503 can be installed in any orientation including upside down. The cooler comes with a hose but one way or another you will have to use the factory lines on your 2005 Chevy Silverado 2500 with 6.0 liter motor. If you want a larger cooler I recommend # D13504. The path of the fluid goes from the transmission and into the factory cooler (whether internal to the radiator or external). Then it will go into the supplemental cooler and from there it will go...

  • Transmission Cooler for 2000 Ford F-250 Towing Heavy 5th Wheel Trailer
    Any fluid leaking from a vehicle is a warning. Often this indicates excessive temperatures in your transmission. If your transmission is stressed to the point of leaking fluid this means that somewhere either a seal, hose or other fitting is being pushed past its limit. My first suggestion is that you try to find that leakage point so you can check whether you have a bad seal or fitting that can be replaced. Driving your truck, let alone towing a trailer with it, with an inadequate trans...
