Replacement of the rear main seal requires removal of the transmission. Due to this labor intensive job, shops will often suggest having the rear main seal replaced anytime the transmission is removed.
The rear main seal may also be referred to as the "rear crankshaft seal."
When a rear main seal leaks, engine oil will often be found dripping from between the engine and the transmission.
