I know I am probably going to beat a dead horse hear but, hear is my situation. I have a '92 SE 4X4 AT. My g/f is driving down the road and with no notice, no bang, no lurch no nothing, she said it felt like someone had put on the brakes. Kind of like she was towing something heavy and it was dragging her down. She pulled over and gave me a call. My first thought: transmission. I did go over the 30,000 mile recommended flush but, the level was fine. I decided to go ahead and flush and fill following the instructions on here. Once completed, it would go into all gears just fine but, when you start moving, you can hear a grinding, crunching noise coming from underneath. I jacked the rear end up, put it in neutral and spun the back wheels by hand to eliminate the rear end and u-joints. No noise there. I left it jacked up and started it, put it in gear and yes, the sound is there. Tranny? TC? Any advice would be greatly appreciated.
