On vehicles that have a rear-wheel drive bias layout, the output shaft seal is at the rear of the transmission extension housing. The seal prevents fluid from leaking out between the transmission and the driveshaft.

Can a slow start cause a transmission leak?

A slow start may mean low transmission fluid caused by a potential leak. What Does a Transmission Repair Involve? The procedures in transmission repair depend on how deeply damaged your transmission is and how long you continued to drive the car once the transmission problems started.
