I have a 1980 Chevy Monte Carlo with a small block Chevy 400 engine with a 525 lift hydraulic roller camshaft and a 700 R4 Transmission with a TCI Saturday Night Special stall converter 2000 rpm stall the transmission rides and shifts great on the normal operation but as you put pressure to it and it changes from 2nd to 3rd gear there's a delay like a hesitation and if you were going up hill while putting pressure on it is like it's slipping and also like the transmission is slipping when you take off on a incline is the slipping from the stall converter? THANKS
