I have an AW4 in a 97 XJ with a ODBII code of P0743.
1. I've searched the forums.
2. I know a P0743 = Torque Converter Clutch Solenoid / Trans Relay Circuits.
3. It clears itself every so often then comes back.
4. I've done a visual check of plugs and such (haven't tried cleaning connectors/plugs yet).
5. Currently there are no symptoms that I can tell.
6. Since the 3rd solenoid only engages and disengages the torque convertor switching in and out of all 4 gears work perfectly.
7. I just had the transmission flushed, filter changed and new gasket installed. No signs of metal shaving n such.
So my questions are:
1. Besides if the torque convertor is engaged coming to a stop and it filling like it is about to stall, how can one tell its engaging and disengaging ?
2. Could it be something other than a dirty connector/plug somewhere?
3. If in deed it is reading the solenoid about to go out or sticking is there a test I can do without poping the pan off? For example, using a VOM check for the resistance across the solenoid wires.
4. What would the exceptable resistance tolerances be?
Any other thoughts, comments or insight is greatly appreciated. Thanks!
