got this code,, cant find a single bit of info on this.
What is TCC, i've heard it somewhere before but never knew what it was.

Can anyone help me with this one?

thanks

 

Diagnostic Trouble Code P0744 indicates a problem with the Solenoid Valve Lock-up Function. This malfunction is detected when the A/T does not shift into fourth gear position or the torque converter clutch does not lock up as instructed by the Transmission Control Module. The electric circuit is good but the A/T failed to lock up. Possbile causes include...
- Torque converter clutch solenoid valve
- Each clutch
- Hydraulic control circuit.

DTC P0744 is entirely consistent with P0734. It's no surprise to find both codes set. They are both warning of the same problem, so whatever fixes one will most likely fix the other.
