Other Automatic Transmission Components

An intricate mechanism like an automatic transmission is going to have its decent share of mechanical challenges as well as maintenance demands, with transmission fluid leakages and steel components eroding from usage. Though we really want them to last permanently, the ASE auto technicians at 12th Street Auto Care Center can repair or change your transmission, with financing if needed.


Axles are a very important part of the drivetrain, which transmit rotating power, or driving torque, to the wheels, located in the back, front or both. They also play an integral part of maintaining the distance between wheels and the position of the wheels held relative to the body of the vehicle.

Output Shaft

The output shaft is connected straight into the automatic transmission from the axle, and then puts the rotating power out of the transmission and into the wheels.

Transmission Oil Pan

Automatic transmission fluid is held within the transmission oil pan. From there, the transmission fluid can travel through the whole of the transmission, into the automatic transmission filter, and back into the transmission oil pan.

Clutch Pack

A series of clutch discs and plates makes up a clutch pack. A clutch pack is held within the automatic transmission, and they are used in order for the vehicle to switch between gears.

Transmission Bands

Transmission bands are flexible, steel plates or bands that are lined with a semi-metallic friction material or an organic lining. Transmission fluid is absorbed by the lining, which aids in the fluid cooling process, and makes the bands tighten around a metal drum. They both take part in the heat dissipation process.
