The SES light is on for my Taurus and I got P1744 from the code scan. I can see that P1744 is pointing to the torque converter clutch, but one strange thing is that I have not noticed any strange behavior from my tranny yet. What kind of typical failure symptoms are for the P1744 code?
I've been having this code for 8000+ miles. Took it to the tranny shop they quote me 2400 for new ford reman tranny so I'd start looking for a new tranny if i were you. It really sucks on the gas milage though, but I'm $2400 short so i'll just drive it til it dies.
The tranny shop checked it told me that "it's internal" and i would need a new ford reman. What's funny is that they originally quoted me 1900 over the phone, but afterward they said oh it's going to be 2400 since it's a SHO. Damn money pit.
Had a test at a local AAMCO shop. They said that it can be either TCC solenoid and/or the torque converter but kept on telling me that they cannot know exactly before opening up the transmission housing. I was asking about the possibility of only the solenoid being in failure and they replied that the pressure from some parts(?) in the torque converter is low, which means that the torque converter needs to be replaced.
I got an impression that they just want me to place a rebuild order for the transmission. I am going to have another testing at another shop on Friday.
I have been to a tranny repair shop today. The mechanic told me that he could not find anything problematic with the transmission and suggested me to keep driving on. However, he recommended me to check the negative battery terminal connector from the wire because it was a little loose. He was suspecting that the code was wrongly set by the PCM from any possible voltage change.
