Detailed Product Overview

The Pioneer Cables FRA-472 is an automatic transmission flexplate engineered for GM applications that require a 168-tooth ring gear and 11.0-inch converter bolt pattern. It is a practical replacement for worn, cracked, or out-of-spec flexplates on Chevrolet Silverado 1500, GMC Sierra 1500, Chevrolet Express, and GMC Savana models. The original-dimension design helps maintain proper starter mesh, converter alignment, and smooth engine-to-transmission operation. This part cross-references GM 12555640 and AA-G182 for the same application.

Common Problems This Part Can Address

• Starter engagement noise caused by worn or damaged ring gear teeth
• Cracks or distortion in the flexplate from age, heat, or stress
• Converter bolt alignment issues from an out-of-spec mounting pattern
• Vibration from an unbalanced or warped flexplate
• Drivetrain noise related to flexplate fatigue

Installation Notes and Tips

Verify tooth count, outside diameter, converter bolt spread, and pitch before installation. Confirm that the vehicle uses the listed 12 to 14 pitch flywheel application and that the torque converter mounting pattern matches the 11.0-inch specification. Inspect the starter, converter, and related hardware for wear before reassembly, and follow the vehicle service manual for torque values and installation sequence.
