I have a 92 4x4 explorer. The automatic shifter seems to be out of adjustment. When I put it in drive, the transmission is in neutral. If I fiddle with the shifter, it will go into drive and I can drive it around the block and it shifts fine into all the gears. How do I adjust this thing??? I know the transmissions are notorious for going bad, but I think since it shifts fine once I get it into gear it must be an adjustment somewhere. Please help me out someone.
