Best answer: What is the normal operating temperature of an automatic transmission?

Normal operating temperature for an automatic transmission is about the same as the engine temperature, i.e., about 195°F. The temperature inside the torque converter, while pulling a big load from a standing start, could easily rise above 350°F. Fluid breakdown often results in harsh shifting and slip-bump concerns.
