Balancing

1. Inspect the flex plate and the torque converter for loose or missing converter to flex plate bolts. Tighten or replace the bolts as necessary.
2. Inspect the torque converter for damaged or missing balance weights. Replace the torque converter if the converter is damaged or if any balance weights are missing.
3. Change the position of the converter to flex plate by 120° at a time in order to cancel out an engine and converter imbalance. Check for vibration improvements in each position.

CAUTION: Check to make sure that the flex plate to converter bolts do not bottom in the holes. Rotate the torque converter by hand after adding the washers.

4. If the unbalanced condition continues, leave the converter to flex plate in the best balanced position. Install longer flex plate to converter bolts and add or remove washers in order to achieve the best balance.
