Don't understand, had what changed? jumps -(vibrates)? neutralizes - (stops pulling)?
Had the trany changed and when u hit 70 and 75 it neutralizes the rpms go all the way up and it stops pullin g also some one told that it was some kind of brake computer
Have someone drive the truck with monitor reading trans data. Test should show why transmission is kicking out. Sounds like electrical problem.
