Issue: On some trucks, a sensor problem may cause the transmission to suddenly downshift to first gear.
This could cause the rear wheels to suddenly slow and potentially create a loss of stability.
Safety Risk: A loss of vehicle stability could cause a loss of control and increase the risk of a crash.
Corrective Actions: The company will notify owners by mail.
Owners will be instructed to take their vehicle to a dealer to have the Powertrain Control Module reprogrammed.
