Hello, I have recently purchased a 1990 Chevy G20 SportVan with a 305 motor and a 700r4 transmission. Right now there is a problem with acceleration at times ( seems as though that the engine may not be getting enough fuel), but also the transmission is slipping. The previous owner had told me it has always consistently been slipping and I'm wondering whether or not the transmission is going out. I have a 2004r transmission laying around and was wondering if it was possible to exchange the 700r4 and swap in the 2004r since they are relatively similar in shape and size.
Does anyone have any information on what I would need to do or if it is possible?
Thanks!
