I took the truck out the other day on the back roads.....at WOT it shifted from 1st-2nd like normal but when it hit 3rd it didn't go into the gear until I let off....driving around normal it shifts fine...its only at WOT...it only happen 2 times and I didn't try anymore after that....I took it last year to get the bands adjusted at 25k..now it has 43k ..do you guys think it could be...thanks
