Bench Test
- With converter removed from vehicle, insert fingers into splined inner race of roller clutch, and ensure stator turns freely clockwise, but does not turn or is very difficult to turn counterclockwise. DO NOT
use driven sprocket support or shafts to turn race, as result may not be correct.
- Using Torque Converter End Play Checker (J-35138), measure torque converter end play. See Fig 1. End play for 245-mm torque converter is 0-.020" (0-.5 mm). End play for 298-mm torque converter is 0-.024" (0-.6 mm). Converter must be replaced if it leaks, is imbalanced or is contaminated with antifreeze.
- Check torque converter bushing-to-stator support clearance by cutting a narrow strip of paper about .003" (.07 mm) thick. Lay paper against the inside diameter of torque converter bushing. Install stator support into torque converter. No clearance should be present.
