SOURCE: trouble code P1744

Torque Converter Clutch System Stuck in Off Position. I would clear that one and see if it comes back. You would be ok to get a smog test done with this code. Its a transmission code. If it does come back I would take it to a transmission shop and have it checked out further. Thanks for using FixYa!

SOURCE: p1744 enginge code tcc solenoid circuit

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 minimum.

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: The Transmission has a little

The po455 is an evap code usually caused by the gas cap leaking or not tight enough.The p1744 is a torque converter clutch engagement issue.My just be a bad solenoid but that is unlikely.The most likely cause is a worn tcc bypass sleeve and valve in the valve body of the transmission and/or a worn pump shaft and /or pump shaft seal.These are internal parts and will require special tools and knowledge to indetify and repair.If your car was in my shop with this code I would probaly recomend an overhaul if it had more than 80 thousand miles on it due to wear that will be in other areas that have not turned into a problem YET.Good Luck!

P1744 - Torque Converter Clutch System Stuck in Off Position.

Either way the problem points to an internal transmission problem.
1. Drive it and see if the codes come back, and see if it is slipping in overdrive.

2. Check the transmission pressure in drive, with the overdrive on and the transmission slipping.

These transmissions have a high failure rate. Have seen internal transmission slippage that showed up in drive with the Overdrive (OD) switch on, but not with the OD switched off. It was related to the coasting clutch being on and off in that range. In that case, there was an internal mechanical transmission problem. We recommend a rebuilt transmission from the dealer and an external transmission cooler - the new rebuilt transmission will last longer.

Good luck (remember to rate this free answer).
