Cadillac Deville 2000- Engine check light code PO741-dealer checked, says transmission must be torn down-Declined service- car has run fine since and no transmission issues experienced for over one year since this happened-What could have caused this?? Bought new, car only has 54,000 miles on it and want to keep it as long as possible, Thanks,Jimbo
If you like go ahead and let someone sell and replace your transmission but here is my suggestion! Check around and see if you can find a minor vacuum leak! This can simply be the big round hose that goes from the fuel injection to the power brake hub! This is normally a push in connector which has about a 1/2 inch hose clamped on it! If there is any kink or the connector is not in correctly a leak will occur and the transmission will shift rough as though you will be thrown out of the vehicle! Try unplugging this connector and plug it back in hard and straight and maybe you will be lucky and fix your problem. If the vacuum is correct your transmission will shift better than you have ever experienced!
I was having the same problem took it to the dealer and they reset the fault. i have been riding good since. they initialy said it was the Torque Converter but turns out it rides fine, been driving that way for about 2 years.
P0741....Torque Converter Clutch Circuit Performance or Stuck Off
P1258 Engine Coolant Overtemperature - Protection Mode Active
the first code is a generic code the latter code is a GM code and if this is correct the engine shut down because it was overheating for whatever reason or the sensor is faulty
