  • Mounting dimensions: 7-1/2" wide x 13-9/16" tall

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.

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

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!

Review from a similar Hyper-Cool in Transmission Coolers


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.

Review from a similar Hyper-Cool in Transmission Coolers


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 .

Review from a similar Hyper-Cool in Transmission Coolers


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.

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.

Review from a similar Hyper-Cool in Transmission Coolers


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.

Review from a similar Hyper-Cool in Transmission Coolers


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.

  • Can the factory Transmission Cooler be Bypassed on a 1996 Ford Taurus with 3.8 Liter Engine
    If you are sure that the problem is a leak in the radiator and not indicative of a larger, potentially worse problem, it is possible to use a transmission cooler to bypass the factory cooler, though it is not the recommended method. What you would need is the largest cooler that will fit in your engine compartment. You will want it as close to the airflow as possible. The out line from the transmission that is currently going to the factory cooler will instead need to go to the new cooler....

  • Best Remote Mount Transmission Cooler with Fan for a 2006 Chevy Silverado 2500HD Duramax/Allison

In order to install this you will need the following: Derale Remote Mounting Kit for Transmission...
