something else is wrong and i cant figure out what it is. My gst wont move, at first it wouldnt move in forward but would haul ass in reverse and now it wont move in forward and reverse. I checked the shafts and everythings ok, i pulled the tranny out opened it up and none of the gears are stripped. Put the tranny back in and nothing. I played with the forward and rev. adjuster arm on the top of the tranny and got nothing. I can turn the shafts from underneath the truck and the wheels do spin. Cant someone give me some ideas. THANK YOU.
