PPE Transmission Fluid Thermal Bypass Valve For 2015-2018 Silverado/Sierra 8L90
Add another level of protection to your transmission with the PPE Transmission Fluid Thermal Bypass Valve, part number 125071000, designed for 2015–2018 Chevrolet Silverado 1500 and GMC Sierra 1500 equipped with the 8L90 8-speed automatic transmission and 3/8" transmission line.
The factory thermal bypass valve contains restrictive internal passages and can fail in the closed position due to debris or mechanical failure. When that happens, transmission fluid may not reach the cooler, which can lead to dangerously high transmission temperatures and reduced transmission life.
The PPE bypass valve replaces the restrictive factory unit with a billet aluminum direct-fit upgrade that maximizes fluid flow to and from the transmission cooler for improved cooling efficiency and long-term reliability.
Features & Benefits:
- Maximizes fluid flow to and from the transmission cooler
- Billet aluminum construction
- Direct fit for OEM 8L90 8-speed transmission and fluid lines
- Helps improve transmission cooling capacity
- Reduces risk of overheating from factory valve restriction
- Service plug with Neodymium magnet and O-ring seal
- Removable plug helps capture and inspect ferrous debris
Part Information:
PPE Part Number: 125071000
GTIN: 840171223149
OEM Reference: GM 13561467
Why Upgrade the Thermal Bypass Valve?
- The factory valve can restrict transmission fluid flow, especially if it begins to fail. This can cause:
- Elevated transmission temperatures
- Poor cooler flow
- Reduced transmission life
- Increased wear under towing or stop-and-go driving
The PPE valve helps eliminate this restriction and improves cooling system performance.
