My cel is on the code is P1744. The code indicates that the torque converter clutch is stuck in the off position. what exactly does that mean? it doesn't happen all the time. what do you think i should replace first? the TSS.
I had the atf changed about 1 month ago.
This sounds bad, read three posts above. In addition, read the below post for a definition. If it were me, I would try changing the TSS ($25 at www.teamfordparts.com) and hope for the best(grasping straws but what can you do....).

Description:
Torque Converter Clutch (TCC) Solenoid:
The torque converter clutch (TCC) solenoid is a pulse width modulating style solenoid. The PWM solenoid is used to control the apply and release of the bypass clutch in the torque converter. By modulating the pulse width of the TCC solenoid the pressure in the S4 circuit varies modulating the apply and release of the bypass clutch in the torque converter.
Symptoms:
Failed ON - Engine stalls in manual 2nd. Engine lugging, poor performance at low engine speeds, harsh shifts.
Failed OFF - Poor fuel economy, overheating, TCC will not engage.
DTCs: P0741**, P7043*, P1741**, P1742**, P1743**, P1744**
Note:
*Output circuit check, generated only by an electrical condition.
Note:
**May also be generated by other NON-electronic related transmission hardware conditions.
Edit. Read this thread too.
