Torque Converter Leak Check

Special Tools:






1. Clean the outside surface of the torque converter.





2. Install the Torque Converter Leak Check Tool and Gasket into the converter hub.

3. WARNING: Always follow proper safety procedures while using the press.





Install the torque converter with the installed leak check tool into the Arbor press.
- Secure the press. Apply enough force from the press to seal the tool into the torque converter.

4. Note: Use clean, dry shop air.





Apply air pressure to the valve on the leak check tool.





5. With air pressure applied to the valve, inspect for leaks at the converter hub, the seams and the studs. A soap bubble solution can be applied around those areas to aid in the diagnosis. If any leaks are present, replace the converter.





6. Remove the air hose. Release the pressure, and then slowly release the press. Remove the converter. Remove the tool.

Torque Converter Impeller to Pump Stator Interference Check

1. CAUTION: To carry out this check, do not use the pump stator support which will be installed in the transmission. Damage to the pump stator support, front pump seal or front pump stator seal may occur.

Note: Obtain a scrapped pump. Remove the stator support. This can be used as a permanent tool to carry out this check.

Position the stator support with the splines up.





2. Mount the (A) torque converter on the (B) stator support so that the splines on the one-way clutch inner race engage the mating splines of the stator support.

3. CAUTION: On diesel applications the torque converter with mult1 plate clutches may rattle and make some scraping noises. This is normal.





Hold the stator support stationary and rotate the torque converter counterclockwise.
- The torque converter should rotate freely, with no signs of scraping.
- If there are signs of scraping, replace the torque converter.
