11" Wide x 12" tall x 7/8" deep, efficient heat exchanger will prolong the life of your transmission and improve its overall performance. Specifically designed for Chevrolet Silverados with late-model, electronic overdrive transmissions.
Features:
Specs:
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.

A year later all is perfect. Reworked my hose connections just to make it better. I haul my race car and gear so maybe 6000lbs my trans Temps have not seen over 190* maybe running 85mph up hill in 3rd gear for extended time it might hit 195* for a short time then after up shift it cools right back down on a hot humid summer day I plan to put a full aluminum radiator in to help just that much more.

Excellent. Keeps the tranny temp about 30 degrees cooler around 190 with the engine at 210when towing my tt. No leaks and works as it should.

The Derale 13504 has kept my transmission from over heating, have towed my travel trailer over 3600 miles no problems with transmission over heating in my 2008 Acadia SLT. Will be installing a auxiliary fan in front of my radiator to assist when in towing this summer. .

After a year still keeping things cool, have had absolutely zero issues, put about 5,000 miles on since the install. Have taken our camper around and this has kept everything under 200 degrees even when towing up grade, as well as when the transmission unlocking the converter adding all that heat to the fluid. So Id say worth it, everyone should do this even on a lightly used truck that doesnt tow necessarily, its a cheap way to save the wear on your transmission and everything below 200 degrees is a good thing.

still working great! I would highly recommend . I have had no issues and would use this product again. I am in Indiana and the trans temp can stay around 120 in the winter but I have had no issues.

Hey Mike could you specify where and how you mounted the second cooler please? Having trouble figuring that out!

TannerI mounted the cooler on the passenger side of the radiator using the stock transmission cooler mount and the headlight mount. The cooler was mounted sideways and all the way to the top of the compartment i dry fit it and made sure the plastic radiator cover would still snap into place as well as the hood closed with no issue before installing it inline with my stock cooler. Tight fit but it works and works well.

How much extra Transmission fluid did you have to add after the transmission was at normal operating temp?

I have been towing my inboard boat all summer and the cooler is doing a great job which I can tell because I have a transmission temperature gauge. The hottest it ever gets is 205 degrees when going uphill.

All is well after a year of use. Still going strong. I regularly drain and refill transmission fluid. Transmission fluid looks red still.

A normal operating temperature for your transmission fluid is between 175-225 degrees F. Adding a transmission cooler effects every vehicle differently based on a number of conditions - such as if youre towing, how heavy a load youre carrying, the outside temps, etc. From what youre describing it sounds like the results youre seeing are keeping your transmission running within that normal range. Even while towing close to your max capacity over the mountains on a warm summer day, your transmission fluid is still at the sweet spot of 200 degrees F.
Do you have a question about this Transmission Cooler?
