PPE 8L90 Transmission Fluid Thermal Bypass Valve For 2015-2018 GMC Chevy 1500

This billet aluminum bypass valve increases fluid flow to the transmission cooler for the GM 8L90 8-speed transmission, providing better cooling and protection against overheating.

• The OEM part has restrictive internal passages.
• Without properly cooled transmission fluid, the demands of towing and rigorous driving shorten the life of transmission components.
• The PPE Bypass Valve eliminates the extremely restrictive mechanical factory valve, maximizing fluid flow to and from the transmission cooler.
• A Neodymium magnet-equipped service plug with an O-ring seal traps ferrous debris.
