Thermostat: Description and Operation
Thermo Bypass Valve - Operation

OPERATION

The air-to-oil transmission cooler system has a thermal bypass valve assembly that controls fluid flow through the cooler. When the transmission fluid is
cold (less then operating temperature), the fluid is routed through the cooler bypass valve without flowing through the transmission cooler. When the
transmission fluid reaches operating temperatures 71°C (160°F) and above, the thermostat closes off the bypass and allowing fluid to flow through the
transmission cooler. The thermal bypass valve is serviced as an assembly.
