How much is it to replace the rear main seal

My car has 140000 miles.
My car has an automatic transmission.

Hello. It is common for the rear main seal to leak on this engine. Over time the seal fails and this occurs. You will need to take this to a shop that can remove the transmission to change the seal out.
