2019-2023 GM 1500/GM HD/Express 6L80/6L90 Transmission Fluid Thermal Bypass Valve, 1/2 Inch Line (125068500)

Description

PPE 6L80/6L90 Transmission Fluid Thermal Bypass Valve for the 2019-2023 GM 1500/GM HD/Express. It replaces the restrictive factory thermal bypass valve on the 6L80 and 6L90 six-speed automatic with a billet aluminum valve that sends full flow to the transmission cooler.

If the factory valve sticks, fluid never reaches the cooler and the transmission can overheat, especially when towing or in stop-and-go driving. The PPE valve removes that restriction to maximize flow to and from the cooler, and a neodymium magnet in the service plug catches metal particles. It installs in place of the stock valve on trucks with 1/2 inch cooler lines.
