Like other vital automotive fluids, transmission fluid deteriorates over time. Hard use – such as frequent stop-and-go city driving, hauling heavy loads, trailer towing – will accelerate the deterioration. That kind of driving raises the operating temperature of the transmission, and heat puts more strain on the transmission and the fluid, which helps facilitate gear shifts, cools the transmission and lubricates moving parts.
