I recently had a leak where the kickdown cable was hooked up to the tranny pan. didnt realize it till the car wouldnt click into first and would slip. filled the tranny fluid up and it was fine for a week. i was driving and at the light the engine would rev high and the car would accelerate reeeeal slow. i knew something was wrong with the tranny right away so i pulled into a sketchy parking lot and check the fluid. the level was full, but the oil smelled burnt. i tried moving the car in all three foward gear, but no dice. reverse worked fine. i called a tranny place and they towed the car and its sitting in the shop till they check it out tommorow morning. if the tranny is shot, should i get a rebuild? or would it be only a little bit more to put a 700r or a 4L60 in instead. it has a th350 in there now that the previous owner put it, but he had no paperwork, and i think he did it him self. how much does it ussually cost to rebuild a tranny as opposed to just putting in the upgraded one like the 700r or the 4L60, used or new?
