Stator to Impeller Interference Check
1. Install the fluid pump support into torque converter. Engage the splines of the one-way clutch inner race with the mating splines of the stator
support.
2. Rotate the torque converter both clockwise and counterclockwise. The fluid pump support should rotate freely without any signs of interference or
scraping within the torque converter.
If there is an indication of scraping, the trailing edges of the stator blades may be interfering with the leading edges of the impeller blades. In such
cases, replace the torque converter.
Torque Converter Operation Test
This test verifies that the torque converter clutch control system and the torque converter are operating properly.
1. Connect tachometer to engine.
2. Bring engine to normal operating temperature by driving vehicle at highway speeds for approximately 15 minutes in overdrive range.
3. After normal operating temperature is reached, maintain constant vehicle speed of about 80 km/h (50 mph). Release throttle for about two seconds
then reapply throttle to previous setting.
