    Should rear main seal be replaced when transmission is out?

    On my 94 FWB. I'm about to install a new tranny and although the seal doesn't appear to be leaking, the car has 110K miles. Do I need a special tool to install the seal like the manual says or can I improvise something?

    If it's not leaking, don't touch it! Putting a seal in without removing the crank rarely holds tight, so it's holding up, don't mess with it. Plus, you don't wanna drop the oil pan to do it anyway, it's a PITA.

    Trust me do it now or else you'll regret it in 10-15K later when you have to drop the tranny again just to replace this damn $5 seal.

    I don't remember if you have to remove the oil pan to replace it because i replaced my oil pan gasket anyway but its really easy to replace the main rear seal use the fel pro seal from autozone its really good and its only 2 screws remove them and the seal comes out then just reinstall the new seal Really easy hard part is removing the trans.

    It's a part with a high chance of failing and no real reason not to replace it. I'm sure its less than $10 at autozone and they have it in stock.

    Maybe I'm just used to Chevy motors, but if it don't leak, don't touch it is my motto.
