Here's what she's doing. I'll go WOT 1st, 2nd, 3rd its fine. at the top of 3rd when it should catch 4th, its like the transmission will downshift then up shift. then to get it to go into 4th (5th is the same thing) smoothly, i have to let out a little (lose 75% of boost) then it will shift and im under the charger for a few seconds till it gets going again. If i dont let out the truck wont shift. it will hang at the top of the gear. Also, only when cold, the transmission will down shift too early, or so it feels, when im coming to a stop and it throws me forward real hard. almost as if the trans doesnt know how fast the truck is going. Also the TC wont lock under WOT without letting out, but from what i understand thats fairly regular when the allison starts seeing higher hp??
