About every 200 miles, check engine lite comes on with code P0741, tourqe converter clutch circute per. or stuck off. Also, min oil indicater comes on, we check the oil and it is at proper level

Code P0741 is a diagnostic trouble code (DTC) that indicates a problem with the torque converter clutch (TCC) circuit in a vehicle's automatic transmission system. The TCC is a hydraulic clutch that allows the engine to continue running while the vehicle is stopped, and it also helps to improve fuel efficiency when driving at highway speeds.
There are several potential causes for a P0741 code, including:

• Failed torque converter clutch solenoid
• Wiring issues, such as damaged or corroded wires
• Failed torque converter clutch
• Failed transmission control module (TCM)

To fix a P0741 code, it will be necessary to diagnose the specific cause of the problem and then perform the appropriate repair. This will typically require the expertise of a trained mechanic, as working on a vehicle's transmission system can be complex and requires specialized tools and knowledge.
If you are experiencing a P0741 code on your vehicle and are unsure how to proceed, it is recommended to take your vehicle to a mechanic or dealership for diagnosis and repair. They will be able to identify the specific cause of the problem and provide the necessary repairs to fix the issue.

Does it die at stops or with foot off throttle and coasting? The overdrive light coming on like that is the transmissions equivalent of the engine check engine light. Fault has been detected and code stored. Would suspect with information provided that the torque converter clutch is locking up but not releasing. You may be able to have this code retrieved with an OBD2 scan tool or at local parts store. You are looking for codes in the 700 range as these are all transmission related codes. ie P0741 or P0742. The P0742 is for torque converter clutch stuck on. P0741 is TCC stuck off

is a faulty transmission solenoid
pan off to replace it
Torque Converter Clutch Circuit Performance or Stuck Off

The Powertrain Control Module (PCM) will set the P0741 diagnostic trouble code when it notices a difference between the rotational speed of the torque converter and the transmission input shaft that is greater than 200 revolutions per minute (RPM).

The transmission oil pan must be removed and the TC solenoid tested, if it works you will need to remove the transmission replace the Torque Converter.

Possible causes - Low transmission fluid level
- Dirty transmission fluid
- Faulty torque converter clutch solenoid valve
- Torque converter clutch solenoid valve harness or connectors
- Torque converter clutch solenoid valve circuit is open or shorted
- Transmission internal mechanical problem

CODE PO741 - TORQUE CONVERTER CLUTCH SYSTEM STUCK OFF WHEN THIS CODE COMES UP YOUR TRANSMISION FLUID TOO LOW OR FLUID + FILTER NEED CHANGING YOU HAVE A RESTRICTION IN TRANSMISSION LINES TO RADIATOR CHECK TO MAKE SURE LINES NOT BENT IN ANY WAY.TCC FEED VALVE OR TCC REGULATOR VALVE IS STUCK OFF DUE TO SEDIMENT OR BINDING.THE OIL PRESSURE SCREEN IS CLOGGED OR DEBRIS IN THE OIL PAN.TAKE CAR TO A TRANSMISSION SHOP GOING TO COST YOU.YOU NEED TRANSMISSION FLUSH AND YOU NEED A FILTER AND FLUID CHANGE.ITS NOT CHEAP FIX BUT YOU CAN CHANGE FLUID + FILTER YOUR SELF TO SEE IF IT HELPS BUT BEST TO HAVE SHOP TO FLUSH OUT TORQUE CONVERTER. PUT NEW TRANSMISSION FLUID IN THE ENTIRE SYSTEM SOUND LIKE OLD FLUID CONTAMINATED WITH SEDIMENT NEED TO GET IT ALL OUT TRANSMISSION.

Replace the solenoid group on the transmission

Audi code P0741 Torque Converter Clutch Circuit Performance or Stuck Off, THIS IS IN MOST CASES A STUCK TORQUE CONVERTER LOCK UP CLUTCH, U MAY NOT EVEN NOTICE THIS AS ALL GEARS WILL WORK JUST NO TORQUE CONVERTER LOCK UP, U WILL NEED TO VERIFY THE TORQUE CONVERTER CLUTCH CIRCUIT IS OK AND IF SO REPLACE THE TRANSMISSION TORQUE CONVERTER.
