The trans in my 87 gn (40,600 miles) has a number of issues. I would imagine with my luck that it is shot. The problems are as follows: Shifts waaaay to hard under part throttle, holds gears way to long under part throttle, and it seems to lock and unlock the converter (if thats possible?) while cruising aprox 40-45 in 3rd. Just wondered if anyone could confirm my darkest fears. Is it terminal? Thanks for any advice...
