I HAVE A CONTINUIG PROBLEM WITH THE CHECK ENGINE LIGHT COMING ON AFTER DRIVING ON THE HIGHWAY----THE CODE IS P0741 (TORQUE CONVERTER CLUTCH SLOENOID VALE STUCK OFF) THE TRANSMISSION WAS REBUILT APPROX 6 MONTHS AGO

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
