SERVICE UPDATEBulletin No.: 10432
Date: January 03, 2011
Subject: 10432 - Service Update for Inventory and Customer Vehicles - Flexplate Bolt Thread Engagement - Expires with Base Warranty
Models:
2011 Chevrolet Camaro
Equipped with 6.2L V8 SFI Engine (RPO L99) and
Automatic Transmission (RPO MYC)
This service update includes vehicles in dealer inventory and customer vehicles that return to the dealership for any reason. It will expire at the end of the involved vehicle's New Vehicle Limited Warranty period.
Purpose
This bulletin provides a service procedure to replace the three torque converter bolts and modify a transmission dust cover on certain 2011 model year Chevrolet Camaro vehicles equipped with 6.2L V8 SFI engine (RPO L99) and automatic transmission (RPO MYC). A small number of these vehicles were produced with torque converter bolts that do not provide adequate thread engagement with the new two piece flywheel. If a bolt loosened, a clanking noise may be noticeable.
This service procedure should be completed as soon as possible on involved vehicles currently in dealer inventory and customer vehicles that return to the dealer for any type of service during the New Vehicle Limited Warranty coverage period.
Vehicles Involved
All involved vehicles are identified by VIN in the Global Warranty Management System - Investigate Vehicle History (GMVIS2) Application. Dealership technicians should always check this site to confirm vehicle involvement prior to beginning any required inspections and/or repairs. It is important to routinely use this tool to verify eligibility because not all similar vehicles may be involved regardless of description or option content.
Additionally, a list of involved vehicles currently in dealer inventory is available on the "Service Update Bulletin Information" link under the "Service" tab in GM GlobalConnect (US) or attached to the GlobalConnect message (Canada) used to release this bulletin. Customer vehicles that return for service, for any reason, and are still covered under the vehicle's base warranty should also be checked for vehicle eligibility.
