Dave Bush at Precision Auto Repair in Garwood NJ damaged my 1970 Cutlass Convertible- He over filled transmission, left bolts out and let water damage occur - he neglected my car and worked on his friend Joe at Westfield Collision's car. He told me my car did not deserve the attention I paid for and overcharged me $1000 for work NOT done. Shoddy work and I my money back to repair his damage

Just changed this tranny to turbo 400. Overfilled tranny and now tranny won't shift out of first. No fluid shown in modulater valve. Any suggestions would be helpful.

Catches 1st gear 3rf gear only when letting car shift itself.

I stall when i sit at traffic lights the problem has got worse than before

I know this is due to the A/C having low pressure but I have removed the A/C altogether due to the cost of replacing it. The engine now surges when I put it into any gear from park. Also, it will continue to accelerate after I have removed my foot form pedal. Any help would be greatly appreciated, riding the bus when you have a car sucks.
