SOURCE: tcc solenoid code
This is a transmission issue, TCC is Torque Converter Control, the solenoid is inside the trans, unless you are a well versed technician I would leave this to the transmission experts, you might try premium assistance for someone that can provide more detailed step by step repair procedures if you are determined to do the repair yourself.

hi..the transaxle converter clutch . tcc. uses a solenoid -operated valve located in the automatic transaxle to mechanically couple the engine flywheel to the output shaft of the transmission through the torque converter.that reduces the slippage loss in the converter.reducing emissions.but check the vss first.which is called the vehicle speed sensor.they both work together .if the vss is not working right it wont call on the tcc.
check this out..

check the vacuum line on the right side of the engine. There should be an elbow connector connecting the line to the engine. Does interior fan only come out of the defroster vents by chance?

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.

Trouble Code: P0742 This should be looked at by a trusted transmission shop in your area to address this problem. This sometimes does require the replacement of the torque converter itself.
