I learned a longtime ago on Mopar 4 speed NP833 trannies to adjust the clutch linkage so the clutch pedal has less than one inch travel before hitting the throw out bearing. that will disenge the clucth diisc from the pressure palte and flywheel about 3/4 way to the floor making it help on shifting and putting the tranny in any gear when stopped
The really need to make sure on any diaphragm type clutch disc that the throw out bearing is not riding on the disc with the pedal out, if it is you need to adjust it so it isn't
