  • Includes complete mounting kit, OEM spec hose with stainless steel clamps, Insta-dapt radiator adapter and hose-barb fittings

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.

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.

Jeep Wrangler

The product is great, the only issue I had was that it did not have the correct connectors for the Jeep Wrangler, but I was able to get some quickly. It's kept my Jeep's Trans fluid temp nice and cool, even when pulling my 3k pound travel trailer.. GREAT!


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.

Steve B.


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.


I can not install the transmission cooler BECAUSE the other parts ordered has not arrived.


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.


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


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.


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.

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.


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

2009 GMC Savana Van

great product from a great company of e

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!

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

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.


Replaced Trans cooler on 1 ton. Temps running lot lower than stock cooler.


Good product. Great instructions. For me, easy to install

  • Can I Replace The Factory Transmission Cooler on a 2013 Chevrolet Silverado
    In regards to your 2013 Chevrolet Silverado, if you will be removing the auxiliary transmission cooler then I recommend using the Derale Series 9000 Plate-Fin Transmission Cooler Kit part # D13614 to replace it. This cooler measures 11" wide x 11-3/8" tall x 1-1/4" deep which you should have plenty of space for. In general we recommend that you install the supplemental transmission cooler in-line the factory transmission cooler (in radiator) and the auxiliary transmission cooler (behind...

  • Best Transmission Cooler for Off-Roading in a 2007 Toyota FJ Cruiser in Year-Round Warm Climate
    The Class rating applied to transmission coolers is to help simplify choosing a cooler for a vehicle. Basically you would think about it in terms of a hitch class rating. So for example if your 2007 Toyota FJ Cruiser has a Class III hitch then a transmission cooler shown as a Class III is a good match. But ultimately you can use any cooler that fits in the intended mounting location. Derale transmission cooler # D13503 is a very popular option. It is a Class III but if you want something...

  • Fitment and Installation of Derale 9000 Series Transmission Cooler Kit on a 2004 Chevrolet Silverado
    I spoke to my contact at Derale and he informed me that you will be able to use the existing lines you've run on your 2004 Chevrolet Silverado for your 8000 series cooler # D13504 to switch out just the cooler portion for the larger 9000 series # D13614 with no extra adapters. I have linked the above mentioned products to this page for your viewing and purchasing convenience.

  • Replacement Transmission Cooler for 2017 Ford Explorer
    It is possible to bypass the original cooler and install a cooler like the # D33504 Derale Series 8000 Plate-Fin Transmission Cooler. It is typically recommended to install this with your factory cooler to assist in the cooling process. I would not recommend this if you plan on doing some heavy towing. Since this would be the only transmission cooler, you will want to use a larger model like a class IV or V. The # D33504 Derale I already mentioned is a Class IV plate-fin cooler that is...

  • 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.

  • 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...

  • Transmission Cooler Recommendation for a 2007 GMC Yukon XL
    Both transmission cooler # D13504 and # D13614 can be used on your 2007 GMC Yukon XL. The difference is the capacity. The larger # D13614 has more capacity so it is more efficient but it also takes up more space. If the larger cooler fits I recommend going with it. You can use fitting # D13035 with either cooler to avoid having to cut and flare lines.

  • Recommended Derale Transmission Cooler for 1997 GMC Safari
    Both the Derale Series 9000 Plate-Fin Transmission Cooler # D13613 and # D13612 will work for your application but I recommend going with the slightly larger # D13613. The 8-7/8 inch height on this unit (compared to 6-3/8 inches on the # D13612) will provide more space for the fluid to travel and thus allow for more efficient cooling on your GMC Safari. The included radiator adapter will fit most vehicles with 5/16 inch transmission lines but it's possible that you may need to cut or...

    The best transmission cooler kit for your 2018 Ram 3500 Dually with the 6.7 Cummins Turbo Diesel engine is going to be the Derale Series 9000 Plate-Fin Transmission Cooler Kit w/ NPT Inlets item # D13611.

  • 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 the Factor Transmission Cooler be Bypassed on a 2004 Jeep Grand Cherokee Laredo 4.0
    The transmission coolers that we carry are designed as supplemental coolers and not to replace a factory cooler. You could bypass the factory cooler but you would need the largest cooler that will fit in the available space in the engine compartment or you would need a cooler that has its own electric fan. For a large cooler or one that is very efficient I recommend # D54006 which is a stacked plate design (most efficient). It measures 13 inches wide by 13-11/16 inches tall by 2 inches...

  • Recommendation for Cooling the Coolant and Transmission Fluid Temperature on a 2008 Chevy Avalanche
    For the radiator coolant temperature, I recommend adding a supplemental fan or fans depending on how much space you have under the hood. There is no limit to the amount of fans you can have. A pusher fan, mounted in front of the radiator pushing air through it, would be the most efficient (provided that the factory fan is mounted on the same side and pushes air through in the same direction). A puller fan would be used on the other side of the radiator to pull air through. The largest electric...

  • 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...

  • Recommended Transmission Cooler for 2017 Infinity QX60
    Transmission coolers can be vehicle specific with their adapters, but for your 2017 Infinity QX60, there isn't a specific fit. I recommend the Derale Series 8000 Plate-Fin Transmission Cooler Kit w/Barb Inlets - Class III - Efficient # D13503 for a good option. The overall dimensions are 8-3/4 tall x 11 wide x 7/8 deep and the dimensions are the greatest restrictions on vehicles. You will want to look at what space you have available in front of your radiator for best function. For...

  • Should Trans Cooler or Suspension Enhancement be Used for Towing with 2007 Chrysler Town and Country
    Since you will be pushing the towing limits of your 2007 Chrysler Town and Country it would be a good idea to use an additional transmission cooler as well as a weight distribution (WD) system to help level your entire towing setup. The WD system will actually do a better job at leveling your towing setup than suspension enhancement will. For a transmission cooler I recommend the Derale Series 9000 Plate-Fin Transmission Cooler Kit # D13614 because it is a Class V plate-fin cooler which...

  • Transmission Cooler for a 1994 Rexhall Aerbus Motorhome with 460 Ford Engine and E40D Transmission
    The Derale Transmission Pan Cooler # D14208 that you referenced has been confirmed to fit the Ford E40D transmission so it would fit and would help to reduce fluid temperatures. For a solution that would work better a supplemental cooler would be a better option. One like the part # D13503 would do a better job reducing the fluid temperature than a pan cooler. The best way to pick out a cooler is to get the largest one that will fit in the available space in front of the radiator. Another...

  • Transmission Cooler Recommendation for a 1992 Ford F-150 Towing Heavy Farm Equipment
    We can't ever safely recommend you exceed the towing capacities of a truck like your 1992 Ford F-150. However, for a transmission cooler for your truck the best option is going to be to go with the largest one you can fit in front of your radiator. The Plate Fin Cooler part # D13614 would be a great option. This is a larger cooler that measures 11W x 11-3/8T x 1-1/4D Inch and is a very efficient design cooler. You will also need the fitting part # D13014 to make the install easier. This...

  • 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.

  • How to Find Line For Derale Cooler For 2017 GMC Savana
    Hey Aaron, So what you'll do when installing the Derale Series 9000 Plate-Fin Transmission Cooler Kit # D13614 in series with the OEM cooler on your 2017 GMC Savana is find the two transmission oil lines that run from the transmission to the radiator, and from what I can see your OEM cooler is right at the front of the radiator. You'll need to find the return line, which you do by warming up the vehicle and feeling the lines, with the colder of the two being the return line, which you'll...

To determine which line is the return line you will want to start with your truck totally cooled off.

    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.

The preferred mounting location would be in front of the radiator for maximum air flow. Installing the cooler behind the radiator...
