4R100 Trans DTC code P1744 - HELP!
Anybody out there ever get this code from their tranny? If so, what causes it and what was the fix? Did a search on the web and found it described as "Torque Converter Clutch System Stuck in Off Possition". I got it yesterday when my overdrive light started flashing and the truck didn't hardly want to move. Any assistance would be appreciated.

p1744 code is the excessive slippage detected by pcm monitoring hydraluc pressures within the trans.What you need to understand is this is a code that can be caused by more than one problem!
A short list of what it could be!
Low fluid
high fluid temp
low pump output pres.
leaking torque converter seals (pressure within)
Bad tft (trans fluid temp sensor)
Bad torque converter clutch(TCC)
Loose valve body bolts within the trans pan
could also be a loose connection electrically at the transmision harness
I hate to say this but your going to be at the mercy of a trans shop or dealer!

What I was told was that the tranny was stuck in "overdrive" plus a variety of other things that I can't remember. Also, when the code was thrown it put the truck in limp mode by causing it to misfire which made me think I had something else going wrong.
Long story short, the reason why the truck didn't hardly want to move from a dead stop was because it was starting out in overdrive and the tranny shop told me that it was going to cost almost as much to fix as it was going to be to replace it. I didn't even hesitate, that's when I ordered the Factory Tech Monster Box.

4r100 Rip
Thanks for the reply.
Unfortunately...yesterday coming home, out of the blue, I get a check engine light on...and then a few seconds later the O/D light starts flashing. I make it home...as I was only about 3 miles away.
Before shutting down...thinking the "noise" I hear is coming from the engine compartment (power steering pump???)...I take a peak under towards the tranny. Sounds are whinning, growling, clanks, etc.
I pull the code with my Equus scan tool...and 1744 comes up. This is what my scanner lists for that code:
• Torque Converter
• Clutch Solenoid
• Circuit Performance
Well...guess I am a victim of the 4R100 tranny.
Although I have had my SD since 87,000 miles and just over 2yrs. My SD now has 101,600 miles. OBTW: When I purchased my SD...I did a complete fluid change. That includes the 4R100 tranny.

I've dealt with Ford remans in Explorers and I wasn't really impressed. They give you the same crappy stock transmission with little or no upgrades at a stealership price. You can get more for your money elsewhere.
