c4 transmission. my stall is not right. I had a shop rebuild it and it should be a 3,800-4,000. they charged me 700.00 to rebuild and re-stall. it was stalling about 3,000 before so I just wanted to raise it a little. it only stalls to about 2,500 - 2,700 now. I called and told them and the guy said some time we don't get it right bring it in and we will try again and hug up on me. its a lot of work to pull it out. my camshaft rpm range is 4,200-7,200 but I shift it at 6,500. this calculator online says with the hp and weight it best pass should be a 10.76. so its about a second slower than it should be
