I just got my c-4 in my 91 GT and I drove it down the road and it would not shift. I jacked it back up and drained the fluid and tried it again. The first time around the block it shifted fine with a little hesitation between 2 and 3. After the tranny heated up it wouldn't shift anymore. Then as I was diving into my driveway it wouldn't even move when I pushed the gas. Any suggestions are appreciated.
