E. Exchange Procedure (Chevy Warranty Repairs Only)

Once the above preliminary diagnosis and/or repairs are made and an exchange unit is still deemed necessary, call Chevrolet TAN and request a transmission specialist. Transmissions repaired under Chevrolet warranty are not available from General Motors Service Parts Operations (GMSPO). Please be prepared to provide serial number from complaint transmission tag, vehicle delivery date and dealer shipping address.

Also, be prepared to provide the necessary information by filling out the reporting form (example attached, reproduce locally) prior to calling.

Chevrolet Technical Assistance Network (TAN) will arrange to ship an exchange unit to your dealership and provide your dealership with a TAN reference number. This number must be written on the return transmission case cover before returning the unit to ZF of North America, Inc.

To increase the effectiveness of the program, the removed transmission unit must be returned immediately (not later than 1 week after date of receipt of replacement unit). Under no circumstances may the removed transmission be retained or purchased by the dealer. Core charge of $3,000 plus administration fee will be charged to the dealer open account after 60 days.

The removed transmission must be returned complete, including shifter assembly, as removed from the vehicle without examination of the unit other than as described in paragraphs A, B, C, or D above. Dealerships returning units that have been even partially disassembled will be judged as violating this procedure and as such will be subject to being billed for all materials furnished.

The exchange unit will have an envelope attached to it. This envelope will contain:

Return shipping label

Reporting form

Leak identification charts

Identification tag explanation chart

Important:
FOR CORVETTE OWNERS WHO WISH TO RETAIN ORIGINAL TRANSMISSION CASE, ZF OF NORTH AMERICA MUST BE ALLOWED TEN (10) WORK DAYS TO REPAIR ORIGINAL UNIT, PLUS SHIPPING TIME (APPROXIMATELY 3 TO 5 WORKING DAYS). If after inspection of the original transmission, it is determined to be non-repairable, the dealer will be notified through the Chevrolet Technical Assistance Network (TAN) and a replacement transmission will be shipped from ZF within twenty-four (24) hours of authorization from TAN.
