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.
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.

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. .

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
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

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 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

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
by: Art CA.02/11/2012
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

Installed the transmission cooler before our 15 hour trip to Florida from Kentucky. Previously had overheating problems with the transmission on long trips. The transmission never overheated during our latest trip with this new transmission cooler installed. Cooler came with everything available, with the exception of tools, to complete the installation. I will install another one if we upgrade to a later model Honda. 266795

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 was driving my older pickup (1997 Toyota T100) up a steep grade to a summit this summer in hot weather. The road was slow with a lot of twists and turns interspersed with straight stretches causing the automatic transmission to upshift and downshift frequently. For the first time since we've owned the car the transmission light came on signaling the trans was overheated. I thought if I want to make my truck last I better do something to prevent a reoccurrence. I had my mechanic install this trams cooler the other day. He mentioned that it was a good idea and is thinking of installing one on his truck that he tows with. He was able to install it in front of the radiator (most efficient position) and said the transmission overheat light should not come on again (peace of mind if you want to avoid a transmission failure). 288127
Made a quick mounting bracket from flat aluminim. Couple of zip ties later and it was installed. Would have liked informatin on about how much TM fluid to add. 180062
by: Homero G.02/28/2015
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
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

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

Product was easy to install with some modifications. Shipping was anything but fast so I don't where all the reviews get they received it in 2 days. I placed my order on Monday at 1:30am. I checked back with etrailer at 5pm and they advised it would not be sent out until Tuesday as they never process an order the same day. I advised I needed it by Friday as I took the day off from work to install and was heading out of town on Saturday. I was then told the only way I would get it by Friday since it didn't go out on Monday was to pay $19.00 for 2day shipping, which I did. I later learned I could have gotten a similar unit from Autozone for $35.00 and picked it up that day. 265099
The install was very simple. This installation video you had was great! We just returned from a 400 mile road trip which put the cooler to good use with no leaks or issues. Great service and a good price. 72125
Kit had everything needed for installing on a 2007 Saturn Outlook, except the connection to the radiator. Just need to buy part D13035. Then it makes install easier. No cutting and flaring lines. The dual fan on the engine side of the factory radiator will have to be removed to push the tie pieces through so the cap to make the tie tight can be added. 202466

Put this trans cooler on a 05 Odyssey because without it they have transmission problems and every automatic needs one realistacly. Heat kills transmissions. This one has enough volume for this size vehicle and keeps it 30 degrees cooler then engine temp. Ran it from the transmission to the radiator and out to the cooler and back to the transmission. This helps with cold weather warm up temps while dropping the normal operating temp to a better operating temp for the transmission. Overall I am highly satisfied and it is providing longevity to my vehicle. 244199

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
by: Jadon W.01/12/2017
I figured since the title specifically labeled my year and make of vehicle. it would at least come with some connections that match it. it is just a universal kit. for install I had to cut the stock lines and also had to get more hose to make it all work right. had to fab up my own mounting bracket since the plastic ties would not go all the way through the radiator due to the A/C, coolant and transmission all being together in one unit. but as for the cooler itself, it looks good and every little bit helps. 332045
by: Jimmy C.09/16/2012
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
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

by: Chad C.05/06/2012
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
What can I say? I got everything that came in the picture, as well as written instructions. I didn't use the written instructions, because e-trailer has a youtube video installation of this on my vehicle (2007 Dodge Caravan). The video was what had convinced my to do this installation myself, and there were no surprises. It all works just fine and I'm happy with the quality of the item, the speed with which they shipped, and the sellers communication. Thumbs up. 297665
This aftermarket transmission cooler was made to work/fit on many late model SUVs and trucks so it didn't look exactly like the original one on my 2003 Toyota Highlander so my mechanic charged me about $50.00 more on the labor because he said it required more work. He installed it and it's working fine for now. Anyway, the order was fast and easy. The sales woman was very helpful! This is my second order from eTrailer and I will order again in the future. 233972
by: John S.05/02/2012
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
by: Mike E.09/07/2013
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
by: Chris H.11/18/2016
This is a great transmission cooler, very sturdy. The only drawback is the suggested mounting method. The tiny little plastic string and clips that come with it just aren't up to the task. The cooler should be mounted with a bracket, period. The plastic clip method is used everywhere, not just here on etrailer, and it's not a good method. I would buy this cooler again and I would make sure that I mounted it properly. 317797
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
by: Chris M.04/12/2011
The cooler was easy to install, or rather the concept was clear after watching the install video. I didn't have alot of room in my particular application. The hose could have been about 6" longer, again based on my application. I had to add roughly 1/2 QT of fluid to make up for the space of the cooler and hose. Awesome site to purchase from with the BEST prices!! Super fast shippers! 11541
by: Scott G03/06/2012
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
by: Mike H05/08/2013
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
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
I installed this transmission oil cooler in my 2003 Honda Odyssey a year ago because this model van is known for its transmission overheating and failure issues. This cooler is more than adequate for the task. Plus, installation was a breeze thanks to the helpful video. I wish I would of have installed this cooler years ago. It would of saved me a tranny rebuild. 246760
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
by: Brandon Z02/15/2016
I wish they had all the items I ordered. I purchased extra items to get free shipping on orders over $100. They did not have one of the items I ordered in stock. They would not honor the free shipping for my order even though they sold me an item they did not have. Their resolution was to cancel my order and create a new one, which did not get free shipping. 237852

I have nothing but great things to say about Etrailer. The service I received when I was looking for a transmission cooler (in my opinion) was second to none. Every question I asked was answered completely. Here we are a year later and the product is still working great. I wouldn't hesitate to use Etrailer in the future for all my towing needs. 283583
Bought to cool 42RLE trans on dakota 2005. Did great job of cooling. Big improvement on transmission shifting. Previously, I had alot of shuddering, from overheating. Did not need special fitting. Used spring clamps instead of hose clamps. Just cut existing tube and slide hose on. Needed extra hose though. Great improvement, worth the money. 328868

These guys are great they had my transmission intercooler to me in a week flat how great is that?!? Will buy more from this worthy retailer 266447
by: Kevin B.03/19/2012
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
by: Rod Y04/12/2012
Got cooler was delivered on time as promised. Pretty simple install. I felt like the hose should of been alittle longer. I had to purchase another section. It would of been more convent for me if the hose was longer even if it cost a little more. Other than that I would recommend it. Now I can drive to Alaska worry free !!!!!! 36975

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

The Derale transmission cooler arrived quickly and in perfect condition. Installation was easy, although the four feet of transmission fluid hose was not near long enough to install cooler on my 1986 F250. I went to six auto parts stores before finally finding some at NAPA. Order some with the cooler for ford trucks. 31335
by: Steve P.09/28/2013
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
by: Patrick Potter06/24/2015
Purchased to install on my 2008 Silverado after towing more than the truck is rated for and running high transmission temperature. It was easy to install. I have not had the opportunity to test it under the conditions which originally brought on the high temps but it seems to have trans running cooler 206943
by: George H.06/04/2012
Got the product arrived in good shape. It took me about 1 hr 45 min to install it on my 2006 Dakota. The fitting for the radator did not work. The stock fitting on the radator has ample tuding to cut and flare a little bit to do the same job. I am well pleased with the order. Thanks 42680
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

This cooler went in pretty easy, I followed YouTube videos to install it. I've had it now over a year and towed with it twice with no incidents. The materials it came with were more than enough, and the mounting system worked fine; at first I had my reservations. 273272
