I just ran my car for the first time since the new motor and trans. I had a road tune done to my car, the motor has tsp 5.3l ported 2.5 heads and tsp ms3 cam. the trans is a built 4l60e and 2500 stall converter. i know the stall is way too low but i got another problem the trans seams to be not shifting or having a delay on shifting from 2-3 it shift perfect from 1-2 then you can hear the motor bouncing off the rev limiter from 2-3 for about a sec then shifts good to 3rd. WHen im driving it normally it shifts fine. and when im half throttle it shifts fine only when im on WOT it does this.
heres my time slip

r/t....... .192
60'.......1.961
330'..... 5.398
1/8......8.243
MPH......85.99
1000......10.676
1/4........12.696
MPH......112.78

i dont know if this could be a trans problem or a tune problem.....its never been dyno tuned and under normal driving it shifts good and half it shifts good. any suggestions or ideas of what it could be?

youguessit

could be either... probably transmission cant keep up with your new combination but you can check the tune...
