Just did a turbo kit and 749 swap on a 89 corvette. Every time it was driven by me city or highway the car was normal. No shifting problems whatsoever. The customer takes it today and droves home(about 10 miles). He said when he got to his street the car "didn't go" He said the engine ras running fine but it really wouldnt move until he dropped the car into 2nd. I taled to 1 guy and he said the car may be sticking in 3rd. I was wondering if it could be a tcc lockup problem. All that I know is that everything was fine until today. Any help is appreciated.

Thanks

 

Sounds like it hurt the 3/4 clutch pack

 

would it be possible for something like this to get damaged either on the dyno or on some of the harder street runs but not really have symptoms until later? The car belongs to an older gentleman who I trust when he says he never drove it hard the entire way home. I had driven it earlier that day, not realy getting into boost much either and the car up and down shifted just as it should. There are only 21,000 miles on this car.

 

3/4 clutch pack has always been a weak link on the 700's. I have never seen one fail with so few miles, but you never know.
