and got the message "Drive to workshop without changing gear" popped right up on the dashboard with TCM error code: C103 and 1709,
but car still be able to start.
(car won't start if leave overnight in cold weather with message "Drive to workshop w/o changing gear," unplug/reconnect battery cable to be able starting the car.
