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
So far so good easy install
Great
Save your transmission from cooking itself. This paired with the Fleece lines is a nice setup! Cooled my temps from 200-210° to around 180-190 on the highway.
My truck was rolling up on 230k miles and she ran warm towing, bought this, installed it in about 25 ish minutes, installation was pretty straight forward. I’d rock just under 200 not towing for a trans temp now I’m at 150 ish for a temp. Definitely recommend to anyone looking to lower their temps. I did the xpd radiator as well. Great fix for both trans and higher coolant temps.
Great service and fast delivery
