C. Exchange Procedure

Once the above preliminary diagnosis and/or repairs are made and an exchange unit is still deemed necessary, contact the "Corvette Launch Center" at 1-800-498-5148. The driveline support assembly is not available from General Motors Service Parts Operations (GMSPO) for vehicles repaired under warranty. Any purchases through GMSPO without prior authorization from the "Corvette Launch Center" may be disallowed on the warranty claim. For vehicles not repaired under warranty, contact the "Corvette Launch Center" for authorization number before ordering from GMSPO.

Please be prepared to provide vehicle delivery date and dealer shipping address.

Dealer must specify if the complaint vehicle has a manual or automatic transmission. The driveline support assemblies are specific for each transmission type.

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

The "Corvette Launch Center" will arrange to ship an exchange unit to your dealership and provide your dealership with a T.A.N. case number. This number must be written, using a permanent marker, on the returned driveline support tube before returning the unit to the supplier for analysis.

To increase the effectiveness of the program, the removed driveline support assembly must be returned immediately (not later than 1 week after date of receipt of replacement unit). Under no circumstances may the removed driveline support be retained or purchased by the dealer.

The removed driveline support must be returned complete, as removed from the vehicle without examination. 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
