Add an extra layer of protection and improve cooling performance for your ZF-8HP90 automatic transmission with the PPE 8HP90 Transmission Fluid Thermal Bypass Valve. This billet aluminum valve replaces the restrictive factory bypass, maximizing fluid flow to your transmission cooler and helping reduce operating temperatures under load.

Key Features

• Improved Fluid Flow: Eliminates the restrictive OEM thermal valve to deliver better flow to the cooler, helping keep transmission temperatures down.
• Billet Aluminum Construction: Durable, high-quality material built to withstand heat and repeated use.
• Magnetic Service Plug: Features a removable neodymium magnet that traps ferrous debris for added protection.
• Easy Installation: Direct replacement design installs quickly with basic hand tools.
• Powder-Coated Finish: Classic black finish looks great and resists corrosion.

Why Upgrade?

The stock thermal bypass valve has restrictive internal passages that can fail or restrict fluid flow to the cooler, especially under heavy use. That can lead to overheating and shortened transmission life. The PPE bypass valve removes this restriction, increasing cooler flow, lowering temperatures, and protecting internal components. The magnetic service plug also helps capture metal particles before they circulate through the system. :contentReference[oaicite:0]{index=0}
