The best way to increase the longevity of your transmission is to keep it cool. Heat is the transmission’s biggest enemy. PPE has the industry’s leading solution. PPE’s Performance Transmission Coolers are bolt-on replacement parts. With a 60% increase in surface area PPE coolers will lower your truck’s fluid temperatures up to 30 degrees when compared to stock. This cooler will pay for itself because of increased fluid and transmission life.
Features:
▪ 60% more surface area for heat rejection
▪ Retains use of factory oil lines
DmaxStore Note:
- When replacing the transmission cooler, you will lose about 1-2 quarts of transmission fluid. We recommend using Transynd Transmission Fluid

Customer Reviews
Did its job improved cooling and nocked 20* out of normal temps. Maintained the lower temp during the heavier longer trips. I would buy it again.
Super easy install, about 30 minutes all together, and runs way cooler up and down mountain passes loaded down.
Fitment is great. Cools good! Just installed this at the same time as my built trans. Currently making a trip across the states with a 28’ camper and temps stay about 90-95 above outside temp
First impression...the trans coolerwas very well packaged to help prevent damage during shipment. The install was very straight forward and helpful. The cooler is very well built as it's about 1.5 inches taller than the oem unit and about twice the size overall to the oem unit. Can tell the product is very high quality. My transmission lines were also starting to leak so I decided to upgrade the oem lines to a fleece performance hose kit at the same time as I replaced the cooler. I would definitely recommend this kit to anyone in need of a better transmission cooler. My truck was starting to get extremely hot while towing my camp trailer so I'm very much hoping that items will show a significant drop in temperatures but time will tell.
quick & easy to install and cools amazingly
