The function of an automobile's transmission involves transmitting power from the engine to the wheels that move the vehicle. Both manual and automatic transmission types operate with the help of a transmission fluid.
Transmission fluid, which may be a special automatic transmission fluid (ATF) or any one of a variety of motor oils, serves several essential purposes. In both a manual transmission and in an automatic transmission, the transmission fluid serves to lubricate the transmission's many moving parts. In an automatic transmission, the transmission fluid also serves as a coolant, and as a viscous medium through which mechanical power is transferred.
Regarding service schedules, recommendations vary from one automobile manufacturer to another and depend on the type of transmission as well as the associated driving conditions. In general however, the transmission fluid in a manual transmission should be changed every 20,000 to 50,000 miles. The transmission fluid in an automatic transmission should be changed every 40,000 to 80,000 miles.
