Excess heat is the #1 killer or transmissions, and for those who tow, race or simply run their diesel hard, properly cooling the transmission fluid is one of the most important things that you can do to increase the life of your transmission. PPEs Performance Transmission Cooler is a bolt-on replacement that lowers the fluid temperatures an additional 20 - 30 degrees over the stock unit. When the mainline pressure is increased with a high performance transmission kit, additional heat is generated and we recommend a Performance Transmission Cooler in these applications.
- Increased surface area provides 60% more heat rejection
- Lowers temps 20-30 degrees over stock units
- Installation takes approx. 30 minutes.
