A transmission is a speed and power-changing device located between the engine and the driving wheels of a vehicle. It provides a means for changing the ratio between engine RPM and driving wheel RPM to best meet each particular driving situation.

Automatic transmission fluid lubricates, cools and cleans internal components of the transmission. It also helps to maintain the hydraulic pressure necessary for the transmission to function. The additives in the transmission fluid can be depleted over time. The automatic transmission filter helps remove dirt and contaminants from the automatic transmission fluid.

Manual transmission fluid provides lubrication to gears, bearings, shafts, and other internal components. Heat, pressure and friction can slowly breakdown the additives in the manual transmission fluid. In addition, small particles of metal may come off the gears as they wear and these metal particles can mix with the fluid. Fluids can also become contaminated with water.
