Chevrolet Recall 01V-283: Power train – transfer case (4-wheel drive)

Affected: 2002 Chevrolet Trailblazer, 2002 GMC Envoy. Filed with NHTSA on September 5, 2001, covering about 895 vehicles.

The problem

Vehicle description: sport utility vehicles (4 wheel-drive). Some of these vehicles were built with a range shift collar in the transmission transfer case that contains cracks.

The risk

This condition could result in a complete fracture of the range shift collar and subsequent loss of vehicle forward and reverse gears, and the inability to maintain "park" position. This increases the risk of a vehicle crash resulting from unintended movement of a parked vehicle.

The fix

Dealers will replace the transfer cases and update the control module calibration. Owner notification began September 6, 2001. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact Chevrolet at 1-800-222-1020 or GMC at 1-800-462-8782.
