Torque Converter Removal

Measure the depth of the torque converter into the transmission’s bell housing

After separating the engine from the transmission:

  • Measure the torque converter's depth into the transmission's bell housing.
  • Use this measurement to ensure that the torque converter is correctly aligned with the transmission oil pump when reinstalling. Use a straight edge and a tape measure or a ruler.
  • Improperly installing the torque converter's hub into the front of the transmission will damage the oil pump.

Torque Converter Inspection

Torque Converter Inspection

Perform a complete inspection of the torque converter after removal. Check the drive hub for burrs and scratches. Most of these are easily removed by polishing the hub with a piece of crocus cloth. If the hub has deep scratches or a significant groove, usually where the transmission pump seal was riding, it may leak transmission fluid into the bellhousing.

Seized Stator

Bench testing a torque converter.

Insert a few fingers into the stator spines and turn. A good stator clutch locks in one direction and spins freely in the other. Replace the torque converter if it has a bad one-way stator clutch. Check the studs and threaded mounts for stripping and wear and check the seams for leakage.
