Transmission was overheating at 190 to 212F. Just put the cooler and highest temp was 162F. So transmission works like new! Fits very tight, but it does.

Keeps my transmission very cool. On a 65 degree morning it runs at ~106 and during the day around 85 degrees it runs from ~120 ~135. Haven’t towed yet but I’d imagine it would stay cooler than factory. Easily mounts in factory location with accompanying mounting hardware (will not use factory mounting holes, you will have to remove factory cooler bracket and drill new mounting holes). Good quality especially for the price point. Would definitely recommend.

Works amazing for my 2005 Escalade. Temperature dropped significantly while doing long distance drives and towing.

I added this cooler to my truck because I started towing a 27-foot trailer and wanted a little extra peace of mind with the transmission temperatures. The kit came with everything I needed, and the cooler itself feels sturdy with a good amount of weight to it. Installation took some time, but nothing about it felt complicated. Once it was mounted and the lines were routed, it sat firmly in place without any rattling or movement. The difference was noticeable on my first tow. The temperatures stayed steadier, especially on long grades where they usually climbed higher. It made the truck feel more prepared for the extra load, and I didn’t have to worry as much about overheating during long drives. If you’re towing anything heavy and want to give your transmission a little more breathing room, this cooler does the job well without making things overly complicated.
