On certain trucks equipped with Electronic Automatic Shift (EAS), a programming logic error in the transmission EAS system may prevent the vehicle's clutch from disengaging when the vehicle is operated in working group or crawler gear range (low-low range). The brake system is not capable of overcoming the engine torque transmitted to the wheels when the vehicle is operated in this gear range. If the clutch fails to disengage, the engine must be shut-down in order to bring the vehicle to a stop, which could result in a vehicle crash causing injury or death. Correction: Dealers will replace the gear shift electronic control unit.
