When those trannys came out there were a lot of problems and constant updates on 'em. They're very easily fouled by debri, just rag lent will stop one. I installed a new ATRA in a vette and it didnt work, had to pull the pan and valve body clean a little piston in there. One of the updates is putting a spring behind it, this one had it but still hung up. What I'm getting at is get a new tranny, you'll get one thats all updated and have a better tranny than you started out with. Look around and get yer best deal and put it in yourself. When I worked at a tranny shop the typical R&R on say a Monte Carlo with a turbo 350 was 1.2 hrs. Thats R&R, fill and test drive. Dont forget a new converter! You dont want to dump all the crap out of yer old converter into your new tranny.
