So I have a 97 Cherokee sport and after a 2 month span of swapping a 95 motor into it. It runs and drives but for some reason only right after I start the jeep up and go to drive down the road, when put into D it seems to stay in one gear and will sounds like it's hits the rev limiter until I let off the gas. Then if I shift it into 3,2 or 1 and then back into drive it shifts gears and will drive and shift perfectly fine until I shut it off and start it again... I'm stumped on this one.
