New to the forum, sorry if this is in wrong area. Anybody out there know how extensive it is to replace the rear main seal in an 05 G6 GT 3.5L? I have a pretty bad leak, 99.9% sure thats where its comin from. Not looking for the walkthrough by any means, I realize I need to have it done somewhere, just wanna know what to anticipate. do you have to remove the tranny and the cradle? any help would be appreciated
