Excess heat is the #1 killer of transmissions. For individuals who tow, race or simply run their diesel hard, know that proper cooling of your transmission fluid is one of the most important things that you can do to increase the life of your transmission. Pacific Performance Engineering’s Performance Transmission Cooler is a bolt-on replacement part that lowers the fluid temperatures up to an additional 20 to 30 degrees over the stock unit. When the mainline pressure is increased with things, such as a high performance transmission kit, you end up with additional heat being generated, so we recommend a Performance Transmission Cooler in such applications.

Features: 60% more surface area for heat rejection Installation takes approx. 30 minutes Retains use of factory oil lines

Available for: 2001-2003, 2003-2005 and 2006-2010 Duramax diesel engines.
