so for a while now i have had a problem with my tranny shifting from second to third when its cold. asked a tranny shop and they said my seal shrunk around the clutch and when it warms up it works fine again. its an auto and i have edge juice on it. gonna get it rebuilt here when it goes but am on a budget and cant afford a super nice built one so am asking you guys today what i can do to build it up pretty good or what you think would be best. Thanks ALOT
