Installation Notes and Tips

Confirm the vehicle uses a 168-tooth flexplate with a 14.13-inch outer diameter before installation. Some listed applications require a weighted flexplate or specific transmission configuration, including certain THM and 6-bolt torque converter setups. Match the original part dimensions and application notes exactly, especially on Chevrolet and GMC truck and police-package vehicles.
