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. PPE'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.
Keep your transmission cool with PPE's performance transmission cooler. Lower your transmission operating temperature with this bolt on replacement. 60% increase in heat rejection surface lowers temperatures 20-30 degrees. This easy installation only takes about 30 minutes. Available for 2001-2010 Duramax diesel engines.
