Code P0744 2009 Nissan Rogue Description

The P0744 diagnostic trouble code (DTC) for a 2009 Nissan Rogue indicates a problem with the Torque Converter Clutch (TCC) circuit that is intermittent. The torque converter is a critical component in an automatic transmission that transfers power from the engine to the transmission. The TCC is responsible for locking the torque converter when the vehicle reaches a certain speed to improve fuel efficiency and reduce heat buildup in the transmission.

Tech Notes for P0744 2009 Nissan Rogue

When a transmission solenoid is working intermittently, 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's 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 mechanical transmission failure, and that the transmission will need to be rebuilt or replaced.
