The Chevy Silverado's P0741 error code indicates a problem with the powertrain control module that involves the timing of the torque converter in relation to the transmission's input shaft. Both rotations need to be synchronized for the engine to work properly. If there is a discrepancy in RPMs, the P0741 code will appear, leading the mechanic to suspect issues with the TCC or torque converter clutch, a malfunctioning solenoid, a faulty transmission control module, engine coolant temperature sensor, low-quality transmission fluid, or damaged wiring in the transmission area. As a vehicle owner, you may notice symptoms such as the "check engine" light turning on, increased fuel consumption, misfires, stalling, and difficulty shifting into high gear at high speeds.
In a Chevy Silverado, when this code pops up, it's usually a problem with the torque converter clutch solenoid.
Are you implying that the solenoid responsible for shifting needs to be replaced, or should I consider replacing the torque converter instead?
