Truck stalls when put in gear?
I installed a 350TH from 1982 Capric Classic behind 1968-327 Chevy. My problem is at 1000rpms the truck stalls when put in gear. When I increase the RPMS to keep it running the truck jumps ahead when put into gear. As far as I know the torque converter is original. Lots of help needed thanks GOWSER.
