Hey all, The tranny on my 02 grand prix stripped the 4th gear shaft a while back & I can't afford to drop 2 grand on getting it rebuilt so I found a used one that has 95,000 on it for a good price at a local salvage yard. Is there anything I can do before I have it installed that will help extend the life of the tranny? I know the PCS is a common problem would it be wise to replace it now? Thanks
