P0741 Torque Converter Clutch Circuit Performance or Stuck Off

Your car actually has a viscous converter clutch inside the torque converter instead of a (mechanical) torque converter clutch to lock up the torque converter for fuel economy improvement. You will see it referred to as the VCC and/or TCC.....

The TCC/VCC has a variety of components in the system including an electrical circuit supplying the transmission, the apply solenoid inside the trans, the torque converter itself, the PCM that controls the apply, etc. It is impossible to diagnose from afar. Unlikely that it is a "sensor" inside the trans as the PCM controls the VCC apply and uses engine and trans data that it receives from a variety of sources. If a "sensor" had failed the trouble code for that sensor would be setting......

Something as simple as the brake switch can cause the VCC to not apply correctly. There is a safety switch on the brake pedal that activates the brake lights and disconnects the VCC circuit. If it is misadjusted then the trans cannot apply the VCC. Lots of other trouble shooting items on the VCC system. If you don't have a service manual and cannot trouble shoot the system, I would recommend a Cadillac dealer as they have the trouble shooting information for the specific VCC that the Cadillac 4T80E trans has that a trans shop is simply not familiar with. No sense working on the trans until you actually know what is wrong.

P0741 Torque Converter Clutch Circuit Performance or Stuck Off

This means that the lock up Torque Converter is not locking up as it should at highway speed or 35 mph and up (I learned that figure in school for Oldsmobile automobiles).

It can lead to less fuel efficiency.

Hope this helps.

Typically - a Transmission flush and filter replacement, along with removing the TCC and cleaning and bench testing it will cure your issue.

If there is that much material floating around in the transmission to plug things up, you might want to consider selling it, or paying for a transmission rebuild down the road.

How many miles on it? has the transmission been serviced at the recommended intervals?

Take Care
