DTC P1744 is "TCC - Excessive Slip
Detected During Full TCC Engagement". Which means that the Torque
Converter Clutch (TCC) is disengaged or the EPC pressure is at the
The most likely cause is a sticking or bad TCC solenoid inside the transmission. You can check the connector at the transmission to make sure it is clean and tight and that it is not damaged in any way.
If the TCC and wiring is okay, then pressure testing of the transmission will need to be done.
A new torque converter from Ford is about $265.00 and about 4 hours labor. Throw in a $40.00 TCC solenoid and I don't think it'll be more than $700.00 at worst.
If the pressure test is good then it's just going to be the $40.00 tcc solenoid and the cost of the transmission oil and filter changed which should be around $150.00
Good luck and hope it's just a loose wire harness to the solenoid which would cost $0.00 and just your time to locate the break in the wire. The other thing to, is to add a transmission fluid additive that would restore the clutch pack in the transmission and Torque Converter.

Testimonial: "thanks a lot very helpful and detailed explanation"
Yes this could be the problem, because you are having backpressure, which is usually the cat, or worst case scenario, you may have a bent or stuck exhaust valve...But what you can do, is disonnect the cat., or the exhaust, and let it run...Now its going to be loud, but if you dont have that back pressure then you know its just the cat., but if you still have it, then you know it maybe a bent or stuck exhaust valve....

Testimonial: "Thank you very much for your hasty response. I will disconnect the exhaust and run it. Let's hope this will prove to be a faulty cat conv. "
You may be on the right track, I've never heard of an EGR valve blowing apart and I've been doing this along time, but I suppose a plugged cat could cause it. Try blocking the pipe, if power goes down, you could be right. Do you, or did you have any codes prior to the valve blowing? A bad cat will usually set a p0420 code. How many miles on it?
