Common Repair Uses

• Replacing a cracked, warped, or damaged flexplate
• Correcting starter ring gear engagement issues on 160-tooth applications
• Restoring proper converter-to-crankshaft connection in automatic transmissions
• Addressing vibration concerns caused by an out-of-balance flexplate
• Servicing GM driveline repairs that require original-style dimensions

Installation Notes

Verify tooth count, outside diameter, inside diameter, and mounting-hole pattern before installation. Several listed applications include first-design or second-design notes, so match the existing flexplate and torque converter mounting style to the vehicle-specific fitment details. Confirm the transmission and engine combination against the notes for your Buick, Chevrolet, Oldsmobile, or Pontiac application before final assembly.
