The transmission plays an important role in how a vehicle functions. It’s connected to the rear portion of your engine and transfers power from the engine to the wheels. Without a transmission, a vehicle simply cannot move. The transmission filter is a vital part of that system and is situated above the transmission pan, which catches any excess fluid, and below a pickup tube that connects to the oil pump, which regulates the pressure of the fluid in the transmission. The transmission filter functions as a sieve to collect contaminants like dirt and debris before sending lubricating fluid to the transmission itself.
