Mishimoto Full-Flow Transmission Thermal Bypass Valve Kit for Select Chrysler/Dodge/Ram 2012-2024 (8HP)

Fits select 2012-2024 Chrysler 300, Dodge Challenger, Dodge Charger, and Ram 1500 TRX with 8HP45 or 845RE transmissions.

The transmission in your Mopar vehicle is the core of its drivetrain performance. To balance cold-weather drivability, Chrysler and Dodge utilized a thermostatic bypass valve in the cooler lines. While designed to reach operating temperature faster, this valve represents a critical failure point; if the internal thermostat sticks, it can lead to rapid transmission overheating and catastrophic failure. For those in warmer climates or those subjecting their vehicles to high-stress driving, this valve also acts as a useless flow restriction.

The Mishimoto Full-Flow Transmission Thermal Bypass Valve Kit (MMTC-GMP-TBVFF) replaces the factory unit with a precision CNC-machined aluminum housing. This full-flow design allows transmission fluid to circulate through the cooler immediately upon startup, providing maximum cooling efficiency and eliminating the risk of a failed thermostat. It is an essential upgrade for towing, track use, or high-ambient temperature environments.
