It's an exhaust valve inside the transmission, when the solenoid isn't working right, the pressurized fluid can't exhaust through the passages, which can cause rough shifting. It has to be taken to a transmission shop, the transmission pan has to be dropped and possibly the valve body to get at the solenoid. Hope this helped.

Testimonial: "This points me in the right direction. Still need to find out which specific solenoid is affected. Thanks!"
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.

SOURCE: I HAVE CODE P0075 P0026
the most likely cause of this code is the MAF sensor or air mass sensor "same thing" this regulates the air to fuel mixture, worth a mention you can try and clean this sensor with carb cleaner and this often cures the fault.
