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

Note: The Derale Insta-dapt radiator adapter fits most vehicles 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.

2005 Nissan Pathfinder

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

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

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

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

Jeep Liberty

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

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.

2003 Chevrolet Avalanche

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

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

Bought this to alleviate some fo the temps on my 2006 Avalanche with the 4l60e automatic. I typically drive about 30 miles one way for work with about 10 minutes of that being in bumper-to-bumper. My temperature gauge for the transmission read about 190 before the installation. Since completing the install, which was very easy, my temps have dropped to about 165-170. I do wish they supplied a better mounting set up rather than the push through zip strips and foam pads. I ended up fabricating brackets out of flat aluminum plate to mount the cooler in a way that created space between it and the A/C condenser for better airflow. 828873

The auxiliary transmission fluid cooler I purchased was excellent! I paid extra for 2 day delivery, and it arrived within 25 hours of ordering! Installation was a little more complicated than the video indicated, but the video was an excellent guide for a do it yourself installation. I save nearly $400 in labor cost! I always try to shop with etrailer.com because their web site and online support are very good at ensuring the products I need are appropriate for my specific vehicle, and they provide installation instructions and videos. 830261

Included everything I needed. I installed this on a 2005 Honda Pilot. Then pulled a 2500lb horse trailer over a thousand miles from sea level to 9000 feet with no issues. I installed onto the AC radiator with the in/out tubes oriented toward the driver side and around the edge. On this year make/model, you can simply pop the top plastic cosmetic trim cover and remove the top radiator brackets without pulling apart the entire front end. To attach to the tranny cooler line, the easiest access is to remove the battery and the battery support plate. This is much easier than some of the methods (possibly necessary) on other year/make/models. 822022

I would not recommend this product for installation on a Chevy Traverse. There are no vehicle specific instructions or videos so I followed the steps shown for a Chevy Equinox. Those steps are the same up to a certain point. The front bumper cover of a Traverse can not be removed following only the steps in that video. This is due to lights and additional fasteners connecting the front bumper cover to the underside of the vehicle. There is also a fan behind the radiator in a Traverse that has to be removed in order to use the zip-tie method of installation. I was able to find all of the fasteners attaching the fan to the radiator and remove it but that did not provide much more room to work. Finally, I appear to have damaged the radiator installing with the zip ties provided so I am now taking my car in to the mechanic. Unfortunately without removing the front bumper cover fully it is difficult to tell where you are installing the zip ties through the radiator. My recommendations would be to have a professional mechanical install this if you have a Traverse, and use the mounting bracket kits that can be ordered separately for this transmission cooler so you don't risk damage to the radiator. 809670

Great cooler and I installed in on my 2013 dodge grand caravan right in front of the radiator. Tubing and hose clamps worked great. You do have to provide your own brackets to make it work. Lastly, the reason why it didn't get 5 starts is b.c the fitting they supplied was incorrect. You can use the existing fittings to make the install work, however it does take a bit of tweaking to get it to 100%. It is what you would expect from an aftermarket installation. Fit and quality of the part is very good. It has been in the van now for over a year with no issues. 806616

Installed in a 2015 GMC canyon. Seems to work fine will update when I get some towing miles logged. Used the D13035 adapter and the D13002 universal mount kit so I did NOT have to zip-tie to the condenser.

    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.

The best way to pick out a transmission cooler is to go with the largest one available that will fit the room in front of the radiator. I attached an install video for you to check out as well.

  • Will a Bigger Transmission Cooler Fit on My 2015 Nissan Rogue?
    Both transmission coolers parts # D13503 and # D13501 work for your 2015 Nissan Rogue SV. Transmission coolers aren't vehicle specific so I always suggest to get the biggest cooler you can fit. The bigger cooler has more surface area to cool the transmission fluid and there is no problem with having cooler fluid. You need to test and see if there is enough room for the bigger cooler to be installed. To test the fit, I suggest using cardboard and making a mock up cooler. The dimensions...

  • Derale Transmission Cooler Installation in 2015 Honda Odyssey
    The bolt shown in the linked video for Derale cooler # D13503 is installed in the hose only temporarily to prevent the transmission fluid from leaking out.

  • Will Transmission Cooler Increase 2006 Honda CR-V's Towing Capacity
    A transmission cooler, such as the Derale Transmission Cooler # D13503, will not increase the towing capacity of your vehicle. Transmission coolers are designed to help improve your CR-V's overall performance and will help prolong the life of your transmission by further cooling the transmission fluid. If you plan on towing with your CR-V, I highly recommend using a transmission cooler in your vehicle to extend the life of your transmission. There are no towing components that will...

  • Should Transmission Cooler for 2013 Honda Pilot Bypass Radiator Cooler
    That's a smart question and when it comes to transmission coolers it is supplemental cooling and because fluid cannot be over-cooled it is recommended to use the cooler in series with your radiator cooler to get optimum cooling. Not doing so to avoid an issue if your radiator happens to fail is not really something I would consider as a pertinent reason (with all due respect to your buddy) only because this is playing to a worst-case scenario which may or may not occur. With that said...

  • 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...
