PRODUCT SAFETY RECALL
SUBJECT:
01064 - TRANSMISSION TRANSFER CASE - INSPECT/REPROGRAM
MODELS:
CERTAIN 2002 4WD CHEVROLET TRAILBLAZER AND GMC ENVOY
CONDITION
General Motors has decided that a defect which relates to motor vehicle safety exists in certain 2002 Chevrolet TrailBlazer and GMC Envoy model vehicles equipped with four wheel drive. The calibration of the active transfer case control module or a range shift collar that was not machined properly may cause insufficient high speed gear engagement. If the gear is not engaged, the vehicle can roll when the transmission is in "park" and a crash could result without warning. A ratcheting noise when the vehicle is in reverse gear or when the driver releases the accelerator pedal while the vehicle is in a drive gear, is a symptom of insufficient gear engagement.
CORRECTION
Dealers are to perform a "clean neutral" test, as described in this bulletin, to detect vehicles with range shift collars that were not machined properly. If a ratcheting noise is detected during the test, dealers are to replace the transfer case. Less than 1% of the tested vehicles will require a transfer case replacement. Dealers are to update the active transfer case control module (ATCM) calibration on all vehicles in order to increase gear engagement.
VEHICLES INVOLVED
Involved are certain 2002 4WD Chevrolet TrailBlazer and GMC Envoy model vehicles equipped with a transmission transfer case and built within the VIN breakpoints shown.
IMPORTANT:
Dealers should confirm vehicle eligibility through GMVIS (GM Vehicle Inquiry System) or GM Access Screen (Canada only) or DCS Screen 445 (IPC only) before beginning campaign repairs. (Not all vehicles within the above breakpoints may be involved.)
Involved vehicles have been identified by Vehicle Identification Number. Computer listings containing the complete Vehicle Identification Number, customer name and address data have been prepared, and are being furnished to involved dealers with the recall bulletin. The customer name and address data furnished will enable dealers to follow up with customers involved in this recall. Any dealer not receiving a computer listing with the recall bulletin has no involved vehicles currently assigned.
These dealer listings may contain customer names and addresses obtained from Motor Vehicle Registration Records. The use of such motor vehicle registration data for any other purpose is a violation of law in several states/provinces/countries. Accordingly, you are urged to limit the use of this listing to the follow-up necessary to complete this recall.
PARTS INFORMATION
Parts required to complete this recall are to be obtained from General Motors Service Parts Operations (GMSPO). Please refer to your "involved vehicles listing" prior to ordering requirements. Normal orders should be placed on a DRO = Daily Replenishment Order. An emergency requirement should be ordered on a CSO = Customer Special Order.
Important:
Due to limited parts availability as well as the cost and size of parts, dealers are encouraged not to order recall parts for use as shelf stock. Parts should only be ordered when the results of the "clean neutral" test determines that it is necessary to replace the transfer case.
Important:
It is estimated that less than 1% of involved vehicles will require a transfer case replacement. Most dealers will not replace a single transfer case as part of this recall. Dealers should call the Technical Assistance Center to obtain the transfer case replacement.
(U.S., IPC) The updated calibration for the transfer case control module is included in TIS 2000 version 9.5 or later versions; and on TIS 2000 # 10 CD-ROM or later releases. The table shows the calibration information.
(Canada) Call Technical Assistance Center for instructions on recalibration information. This is mandatory before the vehicle can be released to the customer.
Notice:
Do not attempt to order the calibration number from GMSPO. The calibration numbers are programmed into the control module via a Techline tool device.

DEALER RECALL RESPONSIBILITY - For US and IPC (US States, Territories, and Possessions)
The US National Traffic and Motor Vehicle Safety Act provides that each vehicle that is subject to a recall of this type must be adequately repaired within a reasonable time after the customer has tendered it for repair. A failure to repair within sixty days after tender of a vehicle is prima facie evidence of failure to repair within a reasonable time. If the condition is not adequately repaired within a reasonable time, the customer may be entitled to an identical or reasonably equivalent vehicle at no charge or to a refund of the purchase price less a reasonable allowance for depreciation. To avoid having to provide these burdensome remedies, every effort must be made to promptly schedule an appointment with each customer and to repair their vehicle as soon as possible. In the recall notification letters, customers are told how to contact the US National Highway Traffic Safety Administration if the recall is not completed within a reasonable time.
DEALER RECALL RESPONSIBILITY - ALL

Dealers are to service all vehicles subject to this recall at no charge to customers, regardless of mileage, age of vehicle, or ownership, from this time forward.
Customers who have recently purchased vehicles sold from your vehicle inventory, and for which there is no customer information indicated on the dealer listing, are to be contacted by the dealer. Arrangements are to be made to make the required correction according to the instructions contained in this bulletin. This could be done by mailing to such customers, a copy of the customer letter is not shown in this bulletin. Recall follow-up cards should not be used for this purpose, since the customer may not as yet have received the notification letter.
