Derale Series 8000 Plate-Fin Transmission Cooler Kit w/Barb Inlets - Class III - Efficient - Jeep Grand Cherokee, 2004

11" Wide x 8-3/4" tall x 7/8" deep, efficient heat exchanger will prolong the life of your transmission and improve its overall performance. Specifically designed for Jeep Grand Cherokees with late-model, electronic overdrive transmissions.

Features:

  • Prolongs life of transmission
  • Improves overall performance
  • Prevents heat-related failures
  • Has furnace-brazed aluminum construction and 3/4" wide turbulator plates for more efficient cooling
  • Includes complete mounting kit, OEM spec hose with stainless steel clamps and Insta-dapt radiator adapter
  • Recommended for full-size cars, trucks and SUVs


Specs:

  • 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
  • 1-Year warranty


Note: The Derale Insta-dapt radiator adapter fits most Jeep Grand Cherokees with 5/16" transmission lines, but not all. In some cases, additional fittings or alteration of the OEM lines or hoses may be required for installation.


One of the more popular cooling systems available, the radiator-style, plate-and-fin heat exchanger provides increased surface area so that fluids can spread out along the finned chambers to cool faster. In addition to the increased surface area, this cooler also features turbulator technology, whereby fluids are agitated continuously, not only to facilitate heat transfer, but also to prevent any undesirable drop in pressure.

Video Transcript for Derale Transmission Coolers D13503 Review

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. .

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

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

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

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

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 - 2/10/2014

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.

Product install was fairly easy. Mine was on a 2009 Silverado 1500 and after a few minutes I figured out that removing the airbox top half made installing the retaining e-clip on the etra radiator fitting so much easier. Temp dropped about 35 degrees under normal driving conditions. Definitely well worth the money and effort. 57164

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. Thanks etrailer for your advise and guick shipping.54831

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

Used in 2003 Trailblazer. Best if you buy the extra hose and mounting kit. Straight-forward install. C-clips are a bugger... Placement is the key. If you have to push in with any large tool, you are doing it wrong and will have to buy a new one! :) Good kit! Love having a video available to walk me thru it!101881

The hardest task to installing was removing the Grille assembly from my vehicle (necessary). Had the cooler bolted in, radiator hardware installed and hose connected in about thirty minutes. All the necessary hardware was supplied with the kit but I opted to bolt the unit down with some drill screws I had. I strongly suggest that customers search for and watch the videos that etrailer has available. Great time saver.98840

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

Product arrived within a few days of ordering. All parts were there and after watching the instructional videos it was pretty straightforward on the install. The only problem I had was when I tied the new lines into the existing return lines using the 13028 Derale Dodge/Jeep Radiator Adapters. I had a lot of trouble getting those fittings into the old lines.93842

Placed it on the 2013 Nissan Pathfinder SL, 4x4, with tow package. This car already has an external cooler tucked in front of the front wheel well driver's side. I wanted to plus it up with the efficient placement of this trans cooler by placing in front of the radiator and connected with the other existing cooler. Had to take off the bumper to make it happen, but it looks great.79342

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!!! Sterling47022

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

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. An extra foot would have been ideal. I made it work, but I had to re-position the cooler when I realized I was going to be a few inches short. So far so good.34354

I installed the Derale D13503 in series with my existing factory installed auxillary cooler for added protection on my Ford Explorer Sport Trac. With the Sport Trac tranny having the reputation for overheating failure, I took the cooling up a notch! I tow a 7X14 enclosed v-nosed trailer, and now I am protected! It was a very easy install, and the included hardware made it pain-free :-)33187

The Derale transmission cooler arrived quickly and in perfect condition.

I went to six auto parts stores before finally finding some at NAPA. Order some with the cooler for ford trucks.31335

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

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 cooler66225

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.

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

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


Comments

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?

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.

  • Transmission Cooler for a 2006 Honda CRV

  • Is an Aftermarket Transmission Cooler Recommended for a 2009 Honda Ridgeline with Tow Package
  • Vehicles come with some type of transmission cooler from the factory. The tow package on your 2009 Honda Ridgeline may include an upgraded version of the factory transmission cooler. 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. I

  • Installation Time and Difficulty of Installing a Transmission Cooler on a 2003 Jeep Grand Cherokee
  • Depending on the vehicle, and where the transmission cooler, # D13503, is going to be installed, it could take around an hour or longer. 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. For a 4.0 liter, use kit # D13028 for 3/8 inch x 3/8 inch hose splicers, or kit # HH41412 for 5/8 inch-18 S.A.E. 45

  • Where Should a Transmission Cooler be Mounted on a 2002 Acura MDX
  • There are actually 3 possible places you could mount the transmission cooler, # D13503. The first location is in front of the A/C condenser core and is the most efficient place. The second most efficient location is between the core and the radiator. You would place the cooler against the radiator. The cooler comes with little pads that go between the two components but they do not separate them very much. Despite this, the area of the radiator that will be blocked is small enough that it wi

  • A transmission cooler is very inexpensive insurance for your transmission, so I would highly recommend the Derale 8000 Series Transmission Cooler you referenced, part # D13503. Although your dry weight is 1600lbs less than the vehicle towing capacity, once you add gear and fill water or propane tanks, you will be climbing closer to that 6500lb figure. The cooler measures 11 inches x 8 inches, and is 7/8 of an inch thick. You will want to take a look in front of your radiator directly behin

  • Can the factory Transmission Cooler be Bypassed on a 1996 Ford Taurus with 3.8 Liter Engine
  • If you are sure that the problem is a leak in the radiator and not indicative of a larger, potentially worse problem, it is possible to use a transmission cooler to bypass the factory cooler, though it is not the recommended method. What you would need is the largest cooler that will fit in your engine compartment. You will want it as close to the airflow as possible. The out line from the transmission that is currently going to the factory cooler will instead need to go to the new cooler. T
