Well.... No. P1744 never has and probably never will "mean that the torque converter clutch is stuck in the off position". There simply is no such DTC. The first step in successful diagnostics is working with all the facts which you obviously choose not to do. Because of that, we don't have all of the pertinent information required to make an EWAG and we get to waste a post just getting you pointed in the right direction.
1. Are there any other DTC's stored or pending in the PCM? My guess is that someone, maybe you, is reading codes and then clearing the KAM so even if there was we wouldn't know what they are and therefore don't have the full story. Without at least one completed drive cycle for both the engine and transmission and all the codes (if there are any others, and experience tells me there will be) available, plus a proper KOEO and KOER self-diagnostic, we can't intelligently go further.
2. The actual verbiage for DTC P1744 is "TCC/Excessive Slip Detected". Notice it says nothing about "the torque converter clutch is stuck in the off position". At least I can't find it. Nowhere.
3. So what's the remedy? Well, the easiest one for everyone involved would be for you to drop your car off with a qualified tech and allow them to complete the diagnostic, isolate the malfunction and repair as required. Alternately you could purchase yourself a repair manual for your car, a scan tool, a 104 pin breakout box and a good DVOM, learn how to use them competently and follow the Ford CD4E diagnostic chart “C”. Or you could just throw parts at it until you accidentally fix the problem. The choice is yours.
Have a nice day.
