GM Releases Bulletin for Improperly Torqued Transmission Fasteners on 2023 – 2024 Corvettes

Early today, GM released Customer Satisfaction Bulletin #N232427051 regarding improperly torqued transmission fasteners on some 2023 – 2024 Corvettes.

According to the document:


Certain 2023-2024 model year Chevrolet Corvette vehicles may have a condition in which the transmission fasteners were improperly torqued.


Dealers will replace the transmission.

Dealers are to service all vehicles subject to this program at no charge to customers, regardless of mileage, age of vehicle, or ownership, through May 31, 2026. Customers who have recently purchased vehicles sold from your vehicle inventory, and for which there is no customer information indicated on the involved vehicle 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. A copy of the customer letter is provided in this bulletin for your use in contacting customers. Program follow-up cards should not be used for this purpose, since the customer may not as yet have received the notification letter.

In summary, whenever a vehicle subject to this program enters your vehicle inventory or is in your facility for service through May 31, 2026, you must take the steps necessary to be sure the program correction has been made before selling or releasing the vehicle.

This program is in effect until May 31, 2026.
