If the converter clutch does not lock at all it may be a problem with the ECM, or some problem with the emissions or sensors have the ECM "out of loop". (in which case the "Check Engine" appears) If the converter clutch is hanging engaged, killing the engine at stops, that is more likely a problem with a solenoid valve in the transaxle. You will need to consult a manual covering the transaxle for the location of the solenoid.
