WEll i don't know a hell of alot aboutthe newwer rigs but isnt's there module that tells the tranny when to shift ? I know it's computer related though by what u are describing .
After further investigation the trans has been pronounced DOA, began making noise and not wanting to do drive reverse shifts. Dealer said it had gone into a programmed limp home mode. Thanks for the feedback.BrianT said:WEll i don't know a hell of alot aboutthe newwer rigs but isnt's there module that tells the tranny when to shift ?
