Code P0741 2017 GMC Sierra Description

The P0741 diagnostic trouble code (DTC) for a 2017 GMC Sierra indicates a problem with the Torque Converter Clutch (TCC) system being stuck off or experiencing transmission hydraulic/mechanical performance issues. The torque converter is a critical component in an automatic transmission that transfers power from the engine to the transmission input shaft. The Torque Converter Clutch (TCC) is responsible for locking the torque converter to improve fuel efficiency and reduce heat generation within the transmission.

Tech Notes for P0741 2017 GMC Sierra

When a transmission solenoid is stuck off, in most cases the problem is not the electrical part of the solenoid; the problem is foreign material obstructing the mechanical function of the solenoid or the flow of the fluid through the transmission valve body. If the transmission fluid is very dirty, it is recommended to change the transmission fluid and if possible, remove the transmission pan for further diagnosis. Excessive debris or metal particles on the transmission pan could be an indication that there is a transmission mechanical failure, and that the transmission will need to be rebuilt or replaced.
