I have a 76 4x4 crew cab that I just picked over the summer. It had not been driven in four years but what in pretty good shape. Anyway after I got it timed and on the road it ran really strong however when it shifts it shifts hard. When I was talking to the guy I bought it from he said he use to use it to haul his camper so they had done a new shift kit on it shortly before he decided to park it. My question is this...Is it ok on the tranny to shift this hard? I assume if there is a load it would not be like that but for everyday driving it will shift hard.
