Question about 1998 Ford Escort
P1744 enginge code tcc solenoid circuit range/perf is this a sensor inside the transmission that needs to be replaced or trans rebuild?
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"
You may need a torque converter lockup solenoid or it could be as simple as a loose, corroded or cut wire going to the tranmission

Check your transmission fluid before spending money at a garage. Low transmission fluid will set off code P1744. That is what triggered it in my 03 Ford Escort ZX2.
