th400 not shifting right
th400 not shifting right I have a Th400 full reverse manual valve body with a pro brake. I removed my progressive nitrous controller and set it up to leave on a 300 shot. The first pass that I did, left hard and good, almost went to the bumper so I sat it down. The next pass that I did the car didn't leave no where like it did the first time and when I would try and shift, it would hit the rev limiter then it would finally shift.....It was doing this on the 2-3 shift mostly, but I tried it today on just the motor and it shifts fine. What could have happened.
Also, When the car gets hot, when you push in the button on the trans brake to put it in reverse the car will not back up, but when it cools down it backs up fine?
