Stacked-plate heat exchangers have long been considered the most effective type of oil or transmission coolers, primarily because of their increased surface area. Allowing fluid to spread out over this larger surface area decreases the time required for heat transfer to take place. As a result, plate coolers typically manage to cool a greater volume of fluid faster than tube-and-fin, or even plate-and-fin, varieties. Add to that a powerful tornado fan that ensures optimum airflow at all times, no matter the environment, and you have a super-efficient heat-exchange unit.

Excellent product, quality parts and fittings for multiple installation platforms. Took about 4 hours to install but was a custom install under bed of truck.


Awesome product! Received it yesterday. Custom fabricated brackets for it to mount below my auxiliary trans cooler on my 07 fx4 f150. Installed the on off switch on out side of transmission and the fan works great!


Awesome remote transmission oil cooler. Attached at the rear under belly of a Toyota FJ Cruiser, 2007.


Love my engine oil cooler. I was having overheating problems with my Dodge truck while towing on a hot day. I asked the guys at etrailer if I should add a bigger radiator, and engine oil cooler or another tranny cooler. They nailed it when they recommended a supplemental engine oil cooler. I now can town my fifth wheel RV trailer on the hottest days and in the mountains without overheating. I do still have to watch the temps and if they start to get over 260 f or so I downshift a gear or two to get greater fluid flows. The only reason I am not giving this 5 stars is that with the supplied hose clamps I was plagued with constant slow leaks. I finally bought a much higher end hose Clamp which did solve the problem.


I was very impressed on quality and ruggedness. Its heavy and works great. This is a must in South Texas especially pulling a trail.


excellent quality product, I have intalled the fan/cooler on a toyota highlander 2010 without tow package not infront of the a/c radiator but exactly at the same place as toyota install the oem transmission cooler just behind the right fog light. I have a travel trailer of 3300 lbs dry, (4000lbs gross weight) and before my transmission temperature was around 215-220 F with a standard transmission cooler(without a fan) infront of the a/c radiator, but now with my new derale fan cooler, its around 180F after a long climb. I am totally satisfied. I had to build a bracket to fit the cooler in this tiny space behind the fog light, it took me 6-7 hours .


I was surprised at the lack of feedback on these products, and the differences in opinions. I tow a fare amount, between 7000lbs and 9500lbs. My vehicle is a 2013 Dodge Ram 1500 with the 8 speed transmission. ( outside temperature 20-30 deg Celsius ). Before I installed this engine cooler my temperature ran around 115 deg Celsius on a flat pull and 130 - 135 deg Celsius on most hills. After a hill it took a long time to drop in temperature, most time it hardly dropped. Now I rarely see 115 deg Celsius on a hill, and recovers to 100 deg Celsius very quickly. So in short I'm very happy with this product. I would recommend it to anyone that Tows.


Mounted between fuel tank and transfer case. Larger 6.0 cooler would go in front of intercooler. Dont need anymore heat there. This was cheaper and works great in this position. Wrapped exhaust near the lines as they have to dump out on right side of trans. and I did not want any hard 90 degree turns with all this extra plumbing. Keeps temps way lower. Also installed oversize/cooler pan.
FYI using temp sensors in pan and in valve body. Pan is regularly 30 degrees cooler than valve body.


Appears to be well-built and wasn't too hard to plumb in series with the existing oil cooler. Unfortunately with my 2010 Suburban it did not make any difference in the oil sump temperature shown by the computer - either daily driving or while towing. I plan on borrowing a laser thermometer to see what the actual input/output temps are.


Great product. Keeps transmission oil cool. Happy with my purchase


Nice product


Easy install, and works as specified. Would put on future high performance vehicles


Have not installed it yet, but looks impressive! This this is like a beast cooler. Will be installing it this week before a long distance rv trip.


Arrived today. need to find time to install. Looks great. box was untaped but I think everything is here. It looks like a quality product. Excellent so far!


Easy install very high quality product.


Great product and prices really awesome service

  • Troubleshooting High Transmission Temperatures after Transmission Cooler Installation
    I would try reversing the direction of the fan on the Derale Transmission Cooler # D15960 that you have installed on your 1994 GMC Truck to see if that will yield you cooler oil temperatures. Generally speaking coolers loose from 25 to 40 percent of their cooling efficiency when the fan pushes air through the cooler as opposed to being pulled through it. Also, depending on the location of the cooler in relation to underside of your vehicle the fan might be fighting the natural airflow...

  • Can the Fan on the Derale D15960 be Reversed?
    To reverse the fan on your Derale # D15960, it is a little bit of a process. What you need to do is remove the fan, flip it around, and then reinstall it.

  • Can a Derale Hyper-Cool Transmission Cooler Replace Factory Cooler on a 1998 Ford Explorer
    You could install the Derale Hyper-Cool transmission cooler # D15960 in place of the factory cooler on your 1998 Ford Explorer. You would have to plug the radiator where the current inlet and outlet locations are for the factory cooler. You may want to replace the transmission lines because if they are wearing out that could be the source of the leak and you would have the same issue with the Derale cooler. I have included a link to the installation instructions for the cooler for you.

  • Will Remote Transmission Cooler D15960 Be Enough for a 2011 Chevy Silverado Towing an 8k 5th Wheel
    The Derale remote transmission cooler, # D15960, is going to definitely provide enough cooling for your 2011 Silverado. The fact that it has its own fan means it will be getting the optimum amount of cooling all the time. You would use it to supplement the factory cooler, not replace it. The dimensions of the cooler are 5-5/8 inches deep, 13 inches wide, and 10 inches tall. You can use these dimensions to find the best place to put the cooler. Since it has its own fan it does not have...

  • How Much Cooling and Fluid Flow does Derale D15960 Hyper Cool Remote Transmission Cooler Provide
    Because there's so many variables involved, such as the outside temperature, the load the engine is experiencing, the motor itself etc, Derale doesn't have a specific number of degrees that their # D15960 Hyper-Cool Remote Transmission Cooler will provide. They could tell me that the cooler would dissipate 46,000 BTU/Hour. The cooler is capable of moving 15.5 gallons per minute. I hope that information is helpful. I've linked to the installation details for you.

  • Amperage Draw of the Derale Hyper-Cool Remote Transmission Cooler Kit Part # D15960
    The Derale Hyper-Cool Remote Transmission Cooler Kit part # D15960 has a continuous amp draw of 4.8 and a surge amp draw of around 7-8. I recommend using a 10 amp fuse with this cooler.

  • Installation of Derale Hyper-Cool Remote Transmission Cooler and BTU Rating
    The Derale Hyper-Cool Remote Transmission Cooler Kit w/ Fan, -8 AN Inlets - Class V # D15960 is designed to be mounted with the hot line routed to the bottom inlet of the cooler and the cool line routed from the top outlet of the cooler. I've attached the installation details to assist. You can have the fittings on either side of the cooler as long as you keep the hot line on the bottom and the cooled return line on the top. I checked with Derale and this unit is rated for 46,000 BTU's...

  • Transmission Cooler Fittings/Hoses for Use in 2008 Ram Cummins 6.7L Diesel with 68RFE Transmission
    My technical contact at Derale advised that the hoses supplied in their Derale Hyper-Cool Remote Transmission Cooler Kit # D15960 have a burst pressure of 300-psi and a guaranteed pressure rating of 250-psi. They have no reported issues with these hoses in any applications.

  • Will an Auxiliary Transmission Cooler Replace a Factory Radiator on 2006 Nissan Frontier
    All of the aftermarket transmission coolers we offer are designed to be installed in addition to the factory cooler. Auxiliary coolers are not designed to take the place of a factory-style cooler. An aftermarket auxiliary cooler, like the # D15960 that you referenced, should be installed after the factory cooler. This way, the fluid is cooled by the factory cooler, and then continues to be cooled as it passes through the aftermarket cooler, before entering the engine. If your factory...

  • Will the Derale Hyper-Cool Remote Transmission Cooler Kit, # D15960 Fit a 2008 Dodge Ram 3500
    You would benefit from installing the Derale Hyper-Cool Remote Transmission Cooler Kit, # D15960, on your 2008 Dodge Ram 3500. The cooler has an in line thermostat that kicks the fan on when the transmission fluid reaches 180 degrees. Because this cooler has its own fan, it can be mounted anywhere there is space without losing efficiency. Take a look at the dimensions near the end of the product page for the dimensions so you can find the best spot on the truck ahead of time. The fan...

  • Recommended Transmission Cooler for a 1956 Pro Street Chevy
    The issue you are going to run into using a standard transmission cooler like the Derale 19-Row Stacked-Plate Transmission Cooler Kit part # D13403 is that it would need to be installed behind the grille, in front of the radiator. This is perfectly doable for most standard applications but in your case you cannot afford to take airflow away from the radiator and intercooler so what you need to go is go with a remote mount option, the Derale Hyper-Cool Remote Transmission Cooler Kit w/ Fan...

  • BTU Rating of Detale D13950 Atomic-Cool Remote Mount Transmission Cooler
    According to Derale, their # D13950 Atomic-Cool Remote Mount Transmission Cooler offers a 22,000 BTU/Hour Cooling Rating and would be a minimally adequate choice for a vehicle used on a drag strip, I'd recommend bumping up to a 46K unit such as the Derale Hyper-Cool # D15960. Drag racing is extremely hard on a transmission, it would make good sense to make the small investment to upgrade to the higher capacity cooler.

  • Remote Transmission Cooler for a 2011 Chevy Silverado with 5.3 Liter Engine
    First, the hose size is not going to be too large. The 2011 Chevy Silverado with the 5.3 liter engine can be used with fitting # D13035 so you will not have to cut and flare any metal lines. The fitting can also be used with remote coolers. Remote cooler # D15960 is a good choice because it is going to provide the maximum amount of cooling for you, even in an arid environment such as summertime in Phoenix. I have included links to the installation details, an FAQ on transmission coolers,...

  • Difference Between Derale Hyper Cool Remote Transmission Fittings D13960 and D15960
    The difference between the kits is the size AN fittings that come with either. Aside from that it's the same coolers and the same fans. The Derale Hyper-Cool Remote Transmission Cooler # D13960 comes with -6 AN inlet fittings and the part # D15960 comes with -8 AN fittings. -6 means the hose is 3/8 inch diameter and -8 means 1/2 inch diameter. The bigger the diameter the more fluid can flow through it. Either are a great option for your truck.

  • Are Power Steering Coolers Designed to Fit Specific Vehicles
    Power steering coolers are not designed or made to fit specific vehicles, and though the Derale 4-Pass Tube-Fin Power Steering Cooler # D13212 with 11/32" hose barb inlets is very likely to work, we do not have access to the specific fittings for your 2013 Ford Expedition or any other vehicle. The only way to do this for sure is to place a quick call to your local Ford dealer, who should be able to give you this information.

  • What is the Hose Diameter on a Ford 4R100 Transmission on a 2001 Ford E-450 Van
    Your 2001 Ford E-450 van should be equipped with a 4R100 transmission that was used on the E-series vans with the 7.3 liter engine. This transmission did use the 3/8 inch diameter hose so using kit # D13022 is the one that you would use. The kit comes with 3/8 line and NPT hose barb but it also comes with an Insta-dapt radiator adapter for 5/16 inch lines that you would not use.

  • Can You Run Larger Cooler Lines Into Smaller Openings?
    Generally speaking, you won't want to run a larger line into a smaller opening with an adapter because the difference will create a buildup of pressure that will likely cause the line to burst, but running a smaller inlet into a larger port is possible. I checked with Derale and they mentioned that running a smaller line into a larger port just means that not as much fluid is going to be pushed into the cooler and it will run less efficiently, but it won't damage the cooler. Derale does...

  • Install Location for Derale Remote Electra Cool Transmission Cooler # D13900 on a 1951 Willys Wagon
    The beauty of a remote cooler is that the fan will provide air flow, so the cooler can be mounted anywhere on the vehicle that has room to accommodate its 15-3/4 by 11-1/2 by 5 inch size. The location you mention should work just fine.

  • Recommended Transmission Cooler for 2008 Dodge Ram 2500 Diesel
    For your Diesel Ram 2500, the Derale Hyper-Cool Remote Transmission Cooler Kit w/ Fan, -8 AN Inlets - Class V # D15960 is not a direct fit but can work. I recommend using the barb fitting if you go with this cooler. The cooler we recommend for your vehicle is the Derale Series 8000 Plate-Fin Transmission Cooler Kit w/Barb Inlets - Class IV # D13504. We have confirmed this to fit with your vehicle. I've attached an installation on another vehicle to assist.

  • Replacement Factory Transmission Cooler For a 2004 GMC Sierra 2500
    In order to replace and upgrade the factory transmission cooler on your 2004 GMC Sierra 2500, I highly recommend the Derale Series 8000 Plate-Fin Transmission Cooler Kit part # D13504 with the Derale Snap-In Radiator Adapter Fitting part # D13035. This will work wonderfully in conjunction with the Derale Hyper-Cool Remote Transmission Cooler Kit that you have and there should be plenty of space to install this directly in place of the factory transmission cooler. The kit also comes with...

  • Replacement Thermostat for Derale Hyper-Cool Remote Transmission Cooler Kit D15960
    Since the threaded part of the Derale Hyper-Cool Remote Transmission Cooler Kit # D15960 broke off I recommend using the Derale Premium In-Line Fan Control Thermostat with -8 AN Fittings # D35021 instead. This has the 180 degree on/165 degree off settings and the thermostat installs differently to the -8 AN connector so it will be a stronger setup.

For this, I recommend Derale Hyper-Cool Remote Transmission Cooler Kit part # D15960.

This is important because increased transmission fluid temperatures result...

  • Can the Factory Transmission Cooler on a 2007 Nissan Frontier be Bypassed
    We don't have a video but I can tell you how you would bypass the factory transmission cooler in the radiator of your 2007 Nissan Frontier. There is a line running to the radiator from the transmission and another running from the radiator to the transmission (the supply and return lines). You would need to take those lines out and plug the inlets where they were. How you do this will depend on if you remove the lines directly at the radiator or further back, leaving the fittings in place...
