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. That "miss" you felt was the TCC disengaging.

If the TCC and wiring is okay, then pressure testing of the transmission will need to be done
