Description

The PPE Transmission Fluid Thermal Bypass Valve is a billet aluminum upgrade for GM 8L90 8-speed transmissions. It replaces the restrictive factory valve to improve transmission fluid flow to the cooler, helping to prevent dangerous overheating during towing and heavy driving conditions.

The design features a built-in service plug equipped with a Neodymium magnet and an O-ring seal to capture ferrous debris within the transmission system.
