I'd see what they offer you. if they offer you a full refund then I would take the money and run. I wouldn't except anything short of a full refund from these guys though. If this is your everyday driver you may not want to run a manual valve body. I just did my tranny up with good parts, converter, hardend input shaft, and a transgo AOD-HP shift kit with a high rev govener. I really like this tranny and it will pull up to about 56-5700 rpms on full throttle shifts. If you looking into beefing your up then I would suggest that kit, good clutches and steels, OD band, hardened input shaft, and a good converter and you'll be very happy. But first I would concentrate on getting your issues fixed. You may want to suggest that someone else fix the tranny but he pays the bill.
