Check engine light/torque converter

I have a 2000 Cadillac DTS, and the check engine light came on. I went and got it inspected and they told me the torque converter wasn't opening properly. Is a way to fix this besides have the part replaced? It won't pass the emissions inspection with the check engine light on.

Blades inside a torque converter do "open and close" based on engine rpm, and they may not be working correctly. However, they should have given you the error code (DTC) which would tell you exactly what was going on. In any case, if you have a torque converter internal problem, it is almost always necessary to replace it as it does not contain any serviceable parts. If it has been a very long time since the transmission fluid was replaced, I would try that first because if you don't, a serious transmission failure is on the horizon.

SOURCE: service emissions system

That will not pass a PA state emission inspection. Don't know what state your in. Take the car to Auto Zone and they will read the trouble code for free. They will let you know what part probably needs to be replaced. You can then buy the part and do-it-yourself or take it to a mechanic knowing what is most likely wrong with it.

SOURCE: when should the timing belt be inspected/replaced

There are no timing belts.
The cams are driven internally via chains that are designed to last the life of the engine.So don't worry about it.
Enjoy your car.

It shouldn't have. You may have a bad transmission. Check your fluids.

I have 2000 cadillac deville and its overheating

P0741 - Torque converter clutch slip speed is exceeding limit; P1258 - High engine metal temperature. Sounds like you have transmission problems - torque converter problems can cause engine overloading, which in turn can cause the overheating. I would start with a complete transmission check before the engine is seriously damage the engine.

My 2000 Cadillac Deville engine light on. Engine code PO420

Catalyst System Efficiency Below Threshold (Bank 1)

A code PO420 may mean that one or more of the following has happened:
  • Leaded fuel was used where unleaded was called for
  • An oxygen sensor is not reading (functioning) properly
  • The engine coolant temperature sensor is not working properly
  • Damaged or leaking exhaust manifold / catalytic converter / exhaust pipe
  • Retarded spark timing
  • The oxygen sensors in front and behind the converter are reporting too similar of reading

  • Check for exhaust leaks at the manifold, pipes, catalytic converter. Repair as required.
  • Use a scope to diagnose the oxygen sensor operation (Tip: The oxygen sensor in front of the catalytic converter normally has a fluctuating waveform. The waveform of the sensor behind the converter should be more steady).
  • Inspect the downstream heated oxygen sensor (HO2), replace if necessary
  • Replace the catalytic converter

No problem the service engine light is on and I am told it reads torque converter

Sounds like P0741 code. Run a self diagnostic. If this is your code, it will likely trigger the check engine light when you're driving at around 80 km/h (overdrive fails). If you're still running, your torque converter clutch is probably stuck on. The fix require the tranny to be opened up and a solenoid changed (14 - 20hrs labour). If you can live with the light coming on and slightly worse fuel economy, then let it be. Make sure you check the codes yourself to be sure. And get it serviced if you notice any change in the way she drives.

Code p0741

Torque Converter Clutch (TCC) Stuck Off.

You may have a faulty TCC solenoid valve.

Simply means the clutch in the torque converter does not engage when you reach cruising speed and will effect overall fuel economy.
Requires workshop/dealer repair.
