With their unique design, Tru-Cool transmission and engine coolers help keep the vehicles you rely on running cool, and that can save you major repair costs.

Here’s how it works:

  • Automatic transmission fluid (ATF) is more viscous when it’s colder. Tru-Cool Low Pressure Drop (LPD) Transmission coolers have a unique cold weather passive bypass that allows the thicker ATF to flow more efficiently through the cooler at the top of the system.

  • As operating temperatures increase, the ATF heats up and becomes thinner. The Tru-Cool system then directs the ATF through the core, where it is cooled.

  • You get optimal heat transfer and improved protection against lube system failure.
