I just aquired a 96 3/4 ton, I tried to hook up the lock-up switch but came across a problem. Mabye one of the tranny experts can chime in and straighten me out. I followed the tst instructions to the T, but now when I engage the TC lock up it stays locked up and I lose the overdrive button and overdrive, and it stays locked up till i kill the truck. when I restart the truck i get the over drive button and overdrive back but if I trip the lock up switch again it goes to again. I'm kinda lost this is my first automatic diesel. I have adjusted the bands to spec and changed the filter. Any help would be greatly appreciated, thanks.
