I finally found a local guy to rebuild my 95 ss' transmission. Is it practical to have him replace the engine's rear main seal , while he has the trans out?
If he has experience changing a Chev one piece in the car.
If the rear cover is not leaking the pan can stay.
Carefully drilled , a couple small sheet metal screws will let you pop it out.
Not carefully and you mark the crank = bad day .
