Its a 98 ZR2 and I think im loosing 1st gear, it will somewhat hesiate shifting into second, put it in manual low (1st) and towards the end of the gear its very slugish and jerky. Im looking for a Heavy duty rebuild kit (for towing, not for racing) but my searches come up useless. Do you guys know of a good trans rebuild kit? (just changed fluid with no luck and no codes, i tow a car trailer about every 2 weeks or so) Thnaks!
