Mishimoto Thermal Bypass Valve Kits

Not Yet Reviewed

Mishimoto thermal bypass valve kits improve upon the failings of stock models that can cause your transmission to overheat. Crafted from CNC-machined billet aluminum, the valves look better and perform better with a fully serviceable 160 degree F thermostat for fast warm-up in cold climates and a thermostat bypass for constant cooling in hot climates. They deliver increased flow over stock models and feature machined cooling fins for added heat dissipation and a durable anodized finish. These thermal bypass valve kits are backed by Mishimoto's Lifetime Warranty.
