2006 UNIMOG U500 Recall

Campaign:

06V457000 on 11/29/2006

Component:

Power train:automatic transmission

Manufactured:

10/31/2003 - 09/29/2006

Affected:

80

Defect:

On certain trucks equipped with the eas transmission option, a programming logic error in the transmission automatic shift system may prevent the vehicle's clutch from disengaging when the vehicle is operated in working group or crawler gear range (low-low range).

Consequence:

The brake system is not capable of overcoming the engine torque transmitted to the wheel ends when the vehicle is operated in working group or crawler gear range. if the clutch fails to disengage the engine must be shut-down in order to bring the vehicle to a stop potentially resulting in a vehicle crash or personal injury.

Correction:

Dealers will modify the automatic shift system to provide reduced engine torque when the brakes are applied while the vehicle is operated in working group or crawler gear range. the gear shift electronic control unit will be replaced and two relays will be added. the recall began on march 28, 2007. owners may contact freightliner at 1-800-547-0712.
