The transmission output shaft is significant because it transmits power to the CV shaft. The output shaft seal is also mounted around the components to keep transmission fluid from leaking.
Automatic transmission output shaft seal functionThe transmission output shaft seal is mounted at the end of the transmission and seals the driveshaft to prevent transmission fluid from spilling. The seal is just as vital as the transmission fluid because without the seal fluid would leak and specific parts would not be able to move as freely. The seal wraps around the output shaft to guarantee that the driveshaft can move while also sealing the fluid.
Common problems with a faulty automatic transmission output shaft sealA faulty automatic transmission output shaft seal can lead to leaking, grinding noises, and low transmission fluid levels.
