Tameless Performance Transmission Fluid Thermal Bypass Valve

Tameless Performance Transmission Fluid Thermal Bypass Valve

Protect your GM transmission and extend its life with Tameless Performance’s Transmission Fluid Thermal Bypass Valve. Crafted from billet aluminum, this performance upgrade replaces the restrictive OEM valve, ensuring a robust and reliable pathway for transmission fluid to reach the cooler under extreme load. With its included magnetic service plug, you can trap metallic debris and maintain a clean system—unlike the factory valve, which lacks this critical feature.

Features

• Billet aluminum construction delivers superior strength and longevity
• Eliminates the restrictive OEM thermal valve for improved cooler fluid flow
• Service plug with neodymium magnet and O‑ring seal captures harmful metal particles and is removable for easy cleaning
• Direct-fit replacement—no lines get cut; just installs in place of the factory part
• Bypass design activates immediately, ensuring consistent cooling under load, towing, or high stop‑and‑go driving

Fitment

Designed to work with GM 6L80 6-speed transmissions equipped with bolt‑on transmission cooler fittings (e.g., many 2014–2018 Chevy and GMC models)
