Transmission Cooling: Notes

The transmission fluid cooler is an oil-to-air fluid cooler with a thermostatic bypass valve. The fluid cooler is mounted between the radiator and the condenser.

• When the transmission fluid is cold and the thermostatic valve is closed, the transmission fluid does not circulate through the fluid cooler.
• As the transmission fluid temperature increases, the thermostatic bypass valve opens and allows the transmission fluid to circulate through the fluid cooler.
