Wanted to make sure my 2nd to 3rd shift points(auto) were good Because I was going racing at Atco raceway, So from a 50mph roll I hit it,Shifts into 3rd fine and 1st to 2nd works fine,No problem,Right? I go down the track,1st to 2nd works,Top of 2nd gear I hit the rev limiter,Would not shift into 3rd on all four passes.On the way home I tried the 50mph roll and it goes into 3rd no problem.What could be wrong.Someone said the trans is going bad,But why is it shifting from a 50mph roll with no problem,But At the track dragracing it would not shift .............................Paul
