i would check the tps( throttle postition sensor) could be faulty sending the wrong signal to the computer also did u correct the speed sensor in the rearend for the change in tire/gear ratios that too could be interfearing >- the transmission is electronic and relys fully on those too sensors to shift

Thanks for the input.I had 4-wheel parts install the 410's and auburn gear they never mentioned anything about the speed sensor.how would i go about getting the correct sensor?that sensor is on top of pumpkin right?i saw it yesterday.had to change gear oil.got water in rear this past weekend.also how can i test tps?i would hate to play guessing games.thanks again!!!

I would also try cleaning out and polishing the inside of the throttle body.
