Has anyone ever used the Torque Ap to monitor torque converter slip (TC_Slip)? (or AE or Snap On)
Been battling a P0741 code with flashing overdrive light (torque converter not locking when commanded to), so far have swapped the oil pump drive shaft for the Sonnax one with fresh seals, and swapped the valve body+solenoids out (8 out of 14 reasons why the torque converter might not lock up lie there).
Just tried Lubegard Red and it seems like the TC Slip RPMs are reduced (went from mid hundreds to low hundreds) but have not had it to highway speeds yet. The Ford diesel truck folks note TC slip values in the low tens (< 40), but their converters have multiple clutch discs I think. Need to know what might be typical for a properly functioning Windstar, particularly a 1998, 1999, 2000 one.
