Converter Clutch Test
NOTE:
Due to the difficulty of feeling converter clutch shift, a tachometer and/or vacuum gauge MUST BE connected to engine.
- To check converter for engagement and disengagement, drive vehicle at approximately 50 MPH and lightly tap brake pedal. Engine RPM and vacuum should increase when clutch disengages.
- Engine RPM will increase when brake pedal is tapped and about 5 seconds after pedal is released. If this does not occur, see AUTO TRANS DIAGNOSIS - FORD E4OD article.
