Got a new one - Periodically, when driving in 'Sport' mode, and usually fairly soon after a cold start, the truck will accelerate and shift normally until it 'sticks' in a specific gear, usually 6 or 7.
If I slow down and even stop, it doesn't downshift, and when you start out, it slips the converter to get going. If you attempt to shift with the paddles or toggle on the shifter, there is no effect, and even the 'max gear' on the screen doesn't change. I've put it in Manual mode, and while the display responds, the trans doesn't shift. Stopping, and putting it in Park or even changing the drive mode (to Normal, or Weather) doesn't make a difference.
The only recovery is to stop, shut the truck down, open a door to disconnect the accessory power, and then reboot and restart. Then the truck behaves normally for the remainder of the run.
It doesn't happen often (yet), but no faults or codes.. Anybody else seen this?
