For 1990-2009 cars only
- Inspect the engine flywheel and the torque converter for loose or missing torque converter-to-engine flywheel bolts. Tighten or replace the bolts as necessary. Refer to Engine Replacement and/or Flywheel to Torque Converter Bolt Replacement in Automatic Transaxle.
- Inspect the torque converter for damaged or missing balance weights. Replace the torque converter if the torque converter is damaged or if any balance weights are missing.
- Change the position of the torque converter to the engine flywheel 120 degrees at a time in order to cancel out an engine and torque converter imbalance. Check for vibration improvements in each position.
- If the unbalanced condition continues, leave the torque converter bolted to the engine flywheel in the best balanced position. Install longer engine flywheel-to-torque converter bolts and add or remove washers in order to achieve the best balance.
Important: Check to make sure that the engine flywheel-to-torque converter bolts do not bottom in the holes. Rotate the torque converter by hand after adding the washers.
