What This Flexplate Helps Address

• Cracked flexplate material from age and repeated load cycling
• Sheared or damaged flexplate teeth that affect starter engagement
• Torque converter mounting issues caused by incorrect hole spacing
• Noise or drivability problems related to a failing flexplate
• Expensive drivetrain damage caused by a broken flexplate

Installation Notes and Tips

Verify the 11.75 in. torque converter mounting hole spread, 139-tooth count, and 14.125 in. outside diameter before installation. Confirm the application against the vehicle’s transmission and engine combination, since flexplate fitment is determined by these dimensions and the listed GM platform coverage. Inspect the starter, torque converter, and mounting surfaces during replacement to help prevent repeat failure.

Quality Assurance
