T-56 Transmission Install Thread
It looks like it has a pretty smooth travel when the pedal is pushed. I had the scope in there while my dad pushed the pedal and it pretty much moved at the same rate as the pedal, no weird inconsistent travel where air might be compressing or anything like that, it's just not enough movement to release the clutch plate because 1-2 inches of pedal travel is being used up just to bring the throwout in contact with the pressure plate fingers. It seems like the only way it could be getting pulled back like that is if the master is somehow sucking it back.
