TORQUE CONVERTER

TORQUE CONVERTER ONE-WAY CLUTCH CHECK
1. Place the torque converter on a workbench with the impeller hub facing up.
2. Place a pick in a slot on the bottom of the stator.
3. While holding the bottom of the stator, rotate the inner race of the one-way clutch.
4. If the inner race rotates in both directions during this check, the stator one-way clutch is slipping.





TORQUE CONVERTER PUMP INSERT CHECK
1. Install the oil pump shaft into the torque converter.
2. Verify that the insert can hold 14 Nm (10 ft. lbs.) of torque.
3. If the insert cannot hold the specified torque, replace the torque converter.
4. Remove the oil pump shaft.





TURBINE TORQUE CHECK
1. Install the Special Service Tools (SSTs) into the turbine splines in the torque converter.
2. Attach a torque wrench and determine the torque required to turn the turbine.
3. If the torque exceeds 8 Nm (36 inch lbs.), replace the torque converter.





TORQUE CONVERTER END PLAY CHECK
1. Install the SSTs into the turbine splines in the torque converter.
2. Attach a dial indicator to the SSTs.
3. Zero the needle of the dial indicator.
4. Pull up on the SSTs and observe the dial indicator reading.
5. If the end play exceeds 1.27 mm (0.05 inch), replace the torque converter.
