Transmission Cooling

The transmission fluid cooler is An Oil-To-Air (OTA) fluid cooler. The fluid cooler is mounted between the radiator and the A/C 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.
