ABSTRACT:
A method of determining the fluid temperature of an automatic transmission wherein a controller is programmed to determine the transmission temperature based on ambient and/or engine coolant temperatures and on observed transmission and engine warm-up rates. The controller may also be programmed to determine the transmission temperature based on the response of the pressure sensors provided.
