• Starter engagement problems caused by worn ring gear teeth
• Vibration from an out-of-balance flexplate
• Noise from damaged or distorted flexplate surfaces
• Fitment issues when replacing an incorrect automatic transmission flexplate

Installation Notes and Tips

Verify tooth count, outside diameter, and mounting dimensions before installation. Confirm the vehicle uses the listed automatic transmission configuration and compare the existing flexplate to the FRA-204 specifications. Proper torque procedures and inspection of related drivetrain components are recommended during replacement.
