Heat and age are mainly what causes transmission fluid to degrade, and this only leads to more overheating. The ideal range for fluid temperature is between 175 and 225 degrees, and every 20 degree drop in fluid temperature can help to double the life of your transmission.

What is a normal trans temp?

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.

What should my transmission temp be before I drive?

The ideal temperature for it is 175 degrees, plus or minus 25 degrees, and when the transmission gets below zero degrees, it gets too thick. The fluid can also fail to lubricate parts when it is too cold, wearing parts down unnecessarily.
