Isolating Vibration

WARNING: This page is about a different variant/trim than selected.
NOTE:

Some engine/transmission combinations cannot be balanced in this manner due to restricted access or limited clearances between the torque converter bolts and the engine.

To isolate and correct a flexplate or torque converter vibration:

  1. With the engine at idle speed and the transmission in PARK or NEUTRAL, observe the vibration.
  2. Turn the engine OFF.
  3. Raise and suitably support the vehicle. Refer to Lifting and Jacking the Vehicle (ZL1) , or Lifting and Jacking the Vehicle (Convertible) .
  4. Remove the torque converter access cover and the bolts (if equipped).
  5. Mark the relationship of the torque converter to the flexplate.
  6. Rotate the torque converter to inspect for defects or missing balance weights.
  7. Index the converter according to "Indexing Torque Converter" procedure located within this procedure.
  8. If the vibration remains, it is most likely caused by the engine.
  9. Refer to "Torque Converter Replacement Guide" located within this procedure.
