  • Inlets: 11/32" hose barb
  • Overall dimensions: 11" wide x 8-3/4" tall x 7/8" deep
  • Distance between inlets: 10-1/4"
  • Mounting dimensions: 8" tall by either 5-1/4" or 6-3/4" wide

Demot-Derale-Transmission-Coolers-D13503 Today we have Derale Series 8000 Plate Fin Transmission Cooler Kit, part number D13503. The kit comes with a transmission cooler, a new line, a hose clamp kit for attaching the new lines, and a mounting kit for the transmission cooler itself. It comes with these long post zips that work as a zip tie to secure this in front of your AC condenser. Transmission coolers are universal fit items. They are not vehicle specific; they are designed to fit anywhere there is space. In order to make sure it will fit your vehicle you want to find a spot where you want to mount a transmission cooler, and measure it to make sure there is adequate room.

Typically you want it in front of the AC condenser or at least in between the AC condenser and the Radiator itself. To give you an idea of some measurements weve got about 11 in width, 9 in height, and the transmission cooler itself is about 1 thick. So make sure that you measure on your vehicle that you will have enough space to mount the transmission cooler. This cooler is covered by 1 year warranty from the manufacturer, and that does it for Derale Series 8000 Plate Fin Transmission Cooler Kit, part number D13503. .

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

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


still working great!

This cooler was easy to install. I did not use the insta-dapter fitting that comes with the cooler. I used a 5/16 barbed coupler instead. One thing I should note is: the instructions state, "warm the vehicle and locate the cooler line and that one will be the return". In my case the radiator made the return line hotter after warming the vehicle for several minutes. I had factory Honda cooler instructions available at install. So return line location was a no brainer. Derale instructions had me second guessing my connections after install was compete. It's installed on a 2002 Honda Odyssey with a newly installed transmission at 70K. I had to remove the headlamp assembly in order to tip the condenser coil far enough to get my hand behind it. 29861

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

I put this on my 2013 Toyota Tacoma PreRunner as I wanted to have the added protection for my transmission, should I tow anything upwards of the max limit. The Tacoma with the tranny cooler and a class IV hitch can reach 6,500 pounds towing capacity, but I doubt I will test that limit. Had the Toyota mechanics install, as the truck was still under warranty and I did not want to take a chance in voiding it if it were put in wrong. I located it in the upper left front corner of the radiator, and using an infrared scanner, the fluid temp shows a noticeable drop from input to output. Bottom line is that was easy to install and does the job it was designed to do. 94413


kenWhat side of condenser did you mount your cooler? pas or driver side?Was there enough hose to reach for the in and out line?if you purchased more how much?How much extra fluid did you have to add after installation?any info will be very helpful. thanks

comment by: george s - 06/19/2014



I had put most of that info in my post. I installed on the drivers side, in front of the condenser and added an additional quart of fluid. Had the dealer do it, not me, so I have no idea if they used additional hose or not.

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


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.

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

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

Installed quickly (once I figured out which line was the input and outlet from the radiator - tip: open line, then have someone start the engine, as soon as you see fluid squirting, stop engine. You now know which line is input/output). Towed boat with it just fine, towing trailer 5K this summer. All the websites say "be sure to install transmission fluid cooler if you are going to tow with your Odyssey." I'm glad this was so straight forward, and a good price (just like the wiring kit I ALSO just got from you). Thank you!!! Sterling 47022

Installed the transmission cooler into a 2005 Honda Pilot. The existing hose is not long enough so had to get a hose splice kit from local automotive supply - not a big deal, but would have been great to have this as part of the kit. The Pilot has two fans behind the radiator which is behind the A/C so I couldn't use the tie down straps, but the holes lined up well with the brace for the power steer cooler and I used stainless steel ties for the top. Overall the quality seems good and the product was delivered on time with no issues. 41261

Installation was done by my local Subaru dealer and at a reasonable cost. I did not want to do it myself since it was a new 2013 Outback and the front bumper had to be removed. They made a couple of brackets and mounted it with bolts instead of using the included plastic ties. We will be towing a Camplite model CL13QBB with a dry weight of 2100 lbs with our 4 cylinder CVT transmission and read the reviews on this cooler and went with it. The fit was perfect.

I bought this intending to install it myself. After getting it, I decided to have a mechanic friend install it and I am glad I did. It took him a couple of hours which means it would have taken me a lot longer... He had to remove the front bumper and lost of other covers, etc. to get at the radiator and condensor. Once all that was removed, he said it was pretty straight forward. I think it is going to work well and I would recommend this product and etrailer to others. 39555

Product is great. Instalation however was a bit more difficult on a 2008 jeep grand cherokee. I was not told when I purchased tne cooler that I would need to buy another adapter. Also I would suggest customers be aware that certain cars like my jeep cannot be serviced at home. When cutting the tranny line you lose some fluid.. I had to take my jeep to the dealership after instalation because the tranny is factory sealed and only the dealership can check or add fluid. 136793

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.

Installed this on my wife's 04 Honda pilot. I wanted to have piece of mind knowing I have extra protection on those sometimes "questionable" Honda transmissions. I would recommend one of these to anyone with a Honda pilot even if you don't plan to tow. The only reason I didn't rate it higher is because the provided hose is not long enough for a pilot. Other than that it is a great product!! 66362

The transmission cooler worked but I had to modify it so it would fit. The quality of the cooler is questionable as well. Very thin material but I guess you get what you pay for. OEM cooler is $216 and this one was $50 so I kinda expected to have to modify or make it fit. Overall it works and I can drive my truck. So I'm happy but I wish it was closer to the manufacturer cooler 66225


We have a few different lines from Derale. The Series 8000 Plate-Fin and Dyno-Cool lines are lower cost items. They will still perform, but there are options if you are looking for something a little more robust. The series 9000 Plate-Fin Coolers and Stacked-Plate coolers would probably be more along the lines of what you are looking for.

Very easy to install providing you have an extra set of hands and are slightly mechanically inclined. The tube supplied was a little shorter than I would have liked it to be.

Not too difficult to install. Slaved it into the system so I can use both the factory coolers and using these items as additional coolers. 51214


Hey Scott, Can you give me some advice on how you slaved it into the existing cooler? My guess would be that it gives you 2x the cooling?

comment by: Mark B - 11/21/2012


Chances are it would not be twice the cooling, but certainly more than either cooler by itself. Instead of by passing the OEM cooler, simply run the return line from the factory cooler to the new Derale cooler, and then out of the Derale back to the transmission. That is how the cooler was set up on the TrailBlazer video.

Cooler is just as described! Not as easy to install as seemed by the instructions. Had to take off the grill, bumper and one headlight to install. 155012

Expert Answers about Derale Series 8000 Plate-Fin Transmission Cooler Kit w/Barb Inlets - Class III - Efficient - D13503Do you have a question about this Transmission Coolers?

  • Recommended Weight Distribution for 2010 Nissan Pathfinder Towing 5800 lb Camper
  • According to my research, your vehicle is capable of towing 6000 lb Trailer Weight/ 600 lb Tongue weight if it is equipped with the V6 motor, or 7000 lb Trailer/ 700 lb tongue weight if equipped with the V8 motor. The use of a weight distribution system will not increase these towing capacities. For the purposes of choosing a weight distribution system, you will need to determine the fully loaded and ready to tow trailer and tongue weight. The weight of anything stored in the cargo area...

  • Will a Derale Transmission Cooler Kit D13503 Work on a 2006 Nissan Titan Towing a 5th Wheel Trailer
  • The Derale Series 8000 Plate-Fin Transmission Cooler Kit, item # D13503, will provide extra cooling to help keep your transmission at normal temperatures when towing. Whether or not any cooler will provide enough cooling depends on many factors specifically related to your vehicle and trailer setup. I did a bit of checking on the 2006 Nissan Titan towing capacities and found that the 2006 Titan is rated for somewhere between 9,200 lbs and 9,500 lbs Gross trailer weight, properly loaded...

  • Can I tow a 30 ft Dutchmen Travel Trailer with a 2003 Ford Explorer
  • To determine if you can tow your 30 ft Dutchmen travel trailer with your 2003 Ford Explorer, you will want to find the towing capacity of your Explorer and compare that to the loaded and ready to tow weight of your trailer. I did some research on your Explorer and found that the Explorer will have different maximum tow ratings depending on how it is equipped. For 2WD models, if you have the 4.0L SOHC engine without a tow package, then the maximum towing capacity of your Explorer...

  • Is A Transmission Cooler Needed For A 1999 Honda Odyssey Towing A 24 foot Travel Trailer
  • Whether or not an aftermarket transmission cooler is needed depends largely on how much weight you will be towing and how often you plan to tow. Transmission fluid can not be overcooled but in the winter it will need longer to warm up if you add an aftermarket cooler that works in line with your current system. You will also want to check your owners manual because it will help you determine when to use a transmission cooler on your vehicle. I do not think that using the Derale Series...

  • Are Transmission Engine Oil and Power Steering Coolers Needed For Towing with a 2007 Honda Pilot
  • Since the manufacturer recommends these aftermarket additions for your Pilot, we cannot suggest differently. The thing to remember is that if you do add these items and a warranty issue comes up, you have shown that you took the proper steps to ensure that your vehicle would perform properly so warranty service should not be a question. Another thing to consider is that heat is the enemy of your engine, transmission, and power steering. Using a cooler will dissipate more heat and prolong...

  • Why are Transmission Coolers Installed on the Fluid Return Line After the Radiator Mounted Cooler
  • The biggest reason that transmission cooler manufacturers and vehicle manufacturers want transmission coolers installed after the factory cooler rather than before it is because the transmission cooler in the radiator is surrounded by the coolant in the radiator. The transmission fluid leaving the radiator mounted cooler can be cooled further by the aftermarket transmission cooler. Installation before the OEM radiator mounted transmission fluid cooler would negate most or all of the...

Regardless of whether or not a cooler is needed, it is a good idea to install one because it will keep the transmission fluid in the optimum operating temperature range, and prolong the life of the transmission.

The Derale Transmission Cooler, # D13502, is one of the recommended coolers for the 2007 Chevy Silverado with the 5.3 liter engine.

  • Can a 2009 Pontiac Vibe Safely Tow a 1,500 Pound Boat Trailer
  • Since you would be right at capacity I do recommend taking any measures feasible in lightening the load. That will make it that much easier on the vehicle. I do believe that properly equipped, the 2009 Pontiac Vibe will be fine towing the 1,500 pounds. Since you will not constantly be towing it up a steep ramp, and that aspect is only a small part of the journey, the Vibe should be just fine. For a trailer hitch, you can use # C12221 but it is for GT models. If you have a GT model then...

There really is not set amount of time because every vehicle is different and different size engines have more or less space and use different fittings. For a 2003 Jeep Cherokee with a 4.7 liter, use Derale Radiator Adapter Fittings, # D13018.
