Mishimoto Full-Flow Bypass Valves

Mishimoto full-flow bypass valves are replacement parts for your vehicle's transmission cooling system. They fix a common problem with factory valves: the built-in thermostat can get stuck or fail. When the factory valve fails, your transmission can dangerously overheat. The Mishimoto bypass valve permanently pushes your transmission fluid through the cooler to prevent overheating.

Here is exactly how each valve works:

* What it does: It completely replaces your factory thermostatic bypass valve. Instead of waiting for the fluid to get hot, it allows fluid to flow through the cooler as soon as you start your vehicle.
* How it helps: It eliminates a major point of failure. Your transmission stays running cooler, which is excellent for hot climates, towing heavy loads, or aggressive driving.
* The build: These valves are made of strong billet aluminum and feature built-in cooling fins to help reduce heat
