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.

Average Customer Rating:  4.8 out of 5 stars   (71 Customer Reviews)

9-3/4" Wide x 10-5/8" tall x 1-1/4" deep, radiator-style heat exchanger improves the performance and overall functioning of your vehicle's transmission. Includes hose-barb adapters to fit the 1/2" NPT inlets.


Easy to install and has worked great on my '06 4Runner v6. A little extra piece of mind for the mountains. This size just barely fits on the passenger side of the radiator - there is a central, vertical support bar behind the grill that prevents a wider cooler from fitting.


This Transmission cooler really works well. It keeps my transmission much cooler while towing heavy trailers. I connected it in series with the factory coolers for a lower operating temperature. If towing or hauling heavy loads I recommend this plate cooler. Also plates remove more heat than tubes.

This cooler is great. The transmission even towing rarely ever gets above 150 degrees. Heat is the main cause of transmission failure and fluid turning to varnish. Highly recommend this cooler.
Steve B - 05/28/2021


This was easy to mount in front of the radiator, and connections were correct to run as 2nd trans cooler for Armada, towing 6500lbs. Immediate change to about 15-20 degrees on long uphill climbs. Just need to inform the tranny guys that it takes more fluid whenever you get a change.


Works great to cool the air going into my Air Compressor tank.

1999 Ford F-250 Super Duty

Installed it on a 99 Ford F250 with a diesel, that was having transmission overheating problem when towing a trailer. Fixed the problem.


Parts arrived fast and in good condition. My setup needs recessed mounting, and I must use the cooler's bolt holes for proper clearence and support. Supplied plastic ties and foam are not quite enough for a secure mounting, and the supplied hose barb fittings are nice aluminum, but I need a 1/2" barb end, not 3/8". These little things are no problem. I'm happy and will buy from e-trailer again.

1996 Ford F-250 Super Duty

Really sturdy and heavy duty, had to move my tire for install but not relocate it on my 96 f250. Took me a little over an hour, had pre existing holes so I only had to drill two of them out.


Packaging was damaged but no damage to cooler due to solid construction. Had done online searches for installation tips and suggestions. All very beneficial. However, this cooler is larger than many I saw online and I had to find an alternate installation location. I was able to find a suitable location in front of radiator and minor modification (drilled two additional mounting holes in mount bracket and trimmed one corner for clearance.) Overall has shown lower transmission operating temps. Have not towed since installation and hope that lower temps carry over to towing a load. I give this product,shipping, and customer service a thumbs up.

GMC Canyon

I added the cooler brfore going on a cross country trip. So far, I have climbed the ozark mountains , Guadalupe mountains, kings canyon and death valley. The highest temperature so far was 186. I'd say it is working better than expected


Works great. Easy to install. Instructions were also good. I also believe this site had videos on the install as well.

2002 Chevrolet Avalanche

This aux transmission kit was easy to install and did just the trick in bringing my engine and trans temps down form towing my trailer. Definitely recommend!

  • Transmission Cooler Recommendation for a 2010 Chevy 1500 Truck
    The Derale Series 9000 Plate-Fin Transmission Cooler # D13614 that you referenced would be a good choice for your 2010 Chevy 1500 truck. This cooler has a GVW rating of 22,500 lbs. You can either bypass the factory cooler altogether, or you can run the coolers one after the other. I would recommend you run the fluid first through the factory cooler and then to the # D13614 and then back to your transmission. This would optimize the cooling of your transmission fluid. I attached an FAQ...

  • Which Transmission Cooler would be Good for a 2008 Chevy Silverado 1500 used for Snow Plowing
    With the kinds of load that a plow truck would be pushing, I would recommend using a transmission cooler on the large end, especially since it is a 1/2 ton truck. The Derale Series 9000 Plate-Fin Class V cooler you were looking at would be a good choice. They radiate plenty of heat due to their all aluminum construction. The cooler measures 11 inches wide, 11-3/8 inches tall and 1-1/4 thick. Locate an area in front of your engine radiator that you would like to mount the cooler and make...

  • Proper Clearance for Derale Series 9000 Transmission Cooler Part # D13614 in 2010 Chevy Impala
    The Derale Series 9000 Transmission cooler can mount either in font of or behind the radiator. The unit measures 11 inches in length, 11-3/8 tall (including mounting tabs) and 1-1/4 inches thick. As this is not a vehicle-specific product, you will have to examine and measure the areas in front of and behind your radiator to see if the proper clearance exists. The preferred mounting location would be in front of the radiator for maximum air flow. Installing the cooler behind the radiator...

  • Transmission Cooler Recommendation for a 2010 Ford F-150
    We do have several transmission coolers that use NPT 1/2 inch fittings though the hose size may be different. It is the inner diameter that you would need to know. The 1/2 inch NPT cooler use a 3/8 inch inner diameter hose. Since transmission fluid cannot be over cooled, the largest cooler that will fit in the engine compartment is recommended. In the 1/2 NPT category, the largest we carry is # D13614 that you have referenced. I have included a link to a video review of this cooler and...

  • Transmission Cooler Availability for a 2014 Subaru XV Crosstrek
    I did some research on your 2014 Subaru XV Crosstrek and it looks like you have a CVT transmission. If your CVT transmission has lines that run from the transmission to the radiator (some do, some do not), you can install a transmission cooler. A transmission cooler is inexpensive insurance that would do a great job of extending the life of your transmission. The best way to pick out a transmission cooler is to measure the distance in front of the radiator and go with the largest one...

  • Recommended Transmission Cooler for 2019 Ford F-150 3.5 EcoBoost with 10 Speed
    The Derale Series 9000 Plate-Fin Transmission Cooler Kit part # D13614 is my recommendation if you want to increase the cooling capacity of the transmission on a 2019 Ford F-150. I can't speak specifically of the 10-speed transmission but so long as the cooler is installed correctly and you add more fluid to the system I see no reason why this could not be done. That said, if you continue to overheat the transmission while towing then you'd be replacing it soon anyway so additional cooling...

  • Transmission Cooler Recommendation for a 2012 Nissan Titan 4x4
    For your 2012 Nissan Titan I recommend Derale Transmission Cooler # D13614. This is a Class V cooler meaning that it is very efficient and will provide a large cooling capacity. The best place to mount the cooler is right behind the grille/in front of the AC condenser core. It can get the most airflow in this position. The line from the transmission will go from the tranny to the factory cooler. From there it needs to go to the new supplemental cooler and then back to the transmission. To...

  • Can Derale Series 9000 Plate-Fin Transmission Cooler Replace OEM Cooler on 2010 Ford Escape
    If you are needing a larger cooler that has 1/2" fittings then you very well could install the Derale Series 9000 Plate-Fin Transmission Cooler Kit # D13614 on your 2010 Ford Escape. Just be sure that you have enough room for the cooler itself (see attached photo). Just please note that even though aftermarket coolers can be very effective, we don't really recommend using them as a replacement for the OEM cooler as they are really meant to be a supplement to the OEM cooler.

  • Can 2009 Toyota Tacoma Safely Tow 4,200 Pound Trailer Long Distances
    If the owner's manual for your 2009 Toyota Tacoma lists a towing capacity of 6,500 pounds then it's safe to tow up to this limit, however as you probably realize, the closer you creep up to this limit the more you're really going to feel the truck work. For example, I can probably run a couple miles without stopping but it's not going to be pretty. Over time this kind of stress can lead to premature wear on various truck components. Now with all of that being said a 4,500 pound trailer...

  • Is 200 Degrees too Hot for Transmission Fluid of 2009 Chevy Tahoe
    As long as the transmission fluid temperatures are staying under 220 degrees you are pretty safe but keeping the fluid as cool as possible only helps so going with a larger or more efficient cooler like the Derale # D13614 in place of or in addition to what you have would be a really great idea. There really isn't such a thing as a cooler that is too big as long as you can make it fit.

  • Recommended Transmission Cooler Add-On for 1999 Ford F-250
    I recommend using the Derale Series 9000 Plate-Fin Transmission Cooler Kit part # D13614 to supplement the factory transmission cooler on a 1999 Ford F-250. This is a stacked cooler which is extra efficient meaning it will provide greater cooling in a smaller package. I recommend installing this inline with the existing cooler and not replacing. Please note, you'll need to add a bit more fluid to the system because of the extra lines and cooler capacity.

  • Do You Have an Adjustable Thermostat that can be Used with Derale Trans Cooler D13614
    For this particular cooler, you would need to use a probe thermostat like part # D16759. This kit has an adjustable turn-on temperature range from 150-240*F. The turn-off is set at 10* lower than the turn on.

  • Do I Need Bigger Trany Cooler for Towing My 2010 Jeep Liberty on a Trailer
    As far as transmission coolers go, you cannot cool transmission fluid too much, so installing the largest cooler that space will allow is perfectly fine and will benefit your transmission the most. The trailer and Jeep you will be towing will probably add up to about 7,000 lbs so I would recommend the Derale Series 9000 Plate-Fin Transmission Cooler Kit, item # D13614. This cooler measures 11 inches wide x 11-3/8 inches tall x 1-1/4 inches deep, so you will need to make sure there is room...

  • Transmission Cooler Recommendation for a 2005 Toyota Tacoma V6
    Transmission coolers are not vehicle specific so there are no specific instructions for vehicles. Our best cooler would be the one that is most efficient. Stacked plate coolers are the most efficient and a good option with an install kit is the Derale Series 9000 Plate-Fin Transmission Cooler Kit, # D13614.

  • Can Factory Transmission Cooler of 2005 Chevy Silverado 2500HD Be Bypassed
    For the best possible cooling of the transmission fluid you ideally would want to route the fluid through both coolers as this would give you the best results. That being, there are several people who will replace their coolers with supplemental ones if the factory one had a leak. This is a large cooler that would do a good job on your truck, but ideally you would route the fluid through both coolers. If you are going to go down to just one cooler I would recommend the part # D13614 instead...

  • Transmission Cooler Recommendation for a 2005 Nissan Titan with 5.6 Liter Engine
    A supplemental automatic transmission cooler is recommended for towing or even for normal driving. Since transmission fluid cannot be overcooled, adding a cooler is a simple way to help prolong the life of the transmission. I recommend the Derale cooler # D13503 for your 2005 Nissan Titan. It is the most popular cooler for your truck. The best place to put it is behind the grille, in front of the AC condenser and radiator. That is where it will work the best.

  • Engine Oil Cooler Recommendation for a Chevy Silverado
    You would want an engine oil cooler like the part # D15902. This would do an excellent job cooling the oil of your truck and has a thermostatic sandwich adapter so that it wouldn't interfere with your truck reaching operating temperature. The cooler measures 17" Wide x 12-1/2" tall x 3/4" deep. As long as you have roof for it in front of your radiator/AC condenser it would work great.

  • Supplemental Transmission Cooler Recommendation for a 2001 Ford F-150
    Factory coolers are often times adequate at best for non-towing applications. For a cheap insurance policy I would add an additional one to your 2001 Ford F-150 since you basically can't over cool a transmission. The cooler you can keep the fluid the longer the transmission will last. A very popular option that would work well for you would be the Derale part # D13614 that you referenced. You would also want the fittings # D13025 to allow the installation of the cooler to be a bit easier...

To determine which line is the return line you will want to start with your truck totally cooled off. Start the truck and put it in drive, apply the brakes firmly and then apply the accelerator slightly so that the engine RPMs climb for a few moments. Put the truck back in park and shut it off.

  • Does the Installation of Derale 15902 on 2015 Toyota 4Runner Require the Use of the Sandwich Adapter
    When installing the Derale # D15902, the Universal thermostatic sandwich adapter is used to add your oil lines to the cooler. It's not necessary to install the adapter during installation if you don't want to have your oil cooled as well. Using this cooler without the adapter will only bring the temperature of your coolant down and not the engine oil with this type of installation. You could look to see if there is an oil filter available that would allow you to use this feature or you...

  • Which Transmission Fluid Line to Access for Installing Secondary Cooler
    Any vehicle to which you want to add a secondary transmission cooler such as the Derale plate-fin type # D13503 needs to have accessible lines you can tap into. If the transmission does not provide this access you can sometimes access the return line from the OEM cooler (which is inside the radiator) at a fitting on the radiator itself. The supplementary cooler needs to install after (downstream of) the OEM cooler that is in the radiator. The OEM cooler reduces the transmission fluid...
