Automatic Transmission Fluid Cooling And Warming
WARNING: This page is about a different variant/trim than selected.
The Automatic Transmission has these temperature phases:
- Warm-up phase - Hot engine coolant from the thermostatic control valve is directed to the Automatic Transmission Fluid (ATF) cooler. This provides a reduced ATF warm-up time.
- Temperature control phase - Hot engine coolant from the thermostatic control valve and cold engine coolant coming from the radiator are mixed. This provides an accurate control to maintain the ATF at the desired operation temperature
- Cooling phase - Cold engine coolant from the radiator is directed to the ATF cooler to provide the maximum ATF cooling capability.
