U have a problem in the transmission torque converter clutch control circuit, most likely the solenoid switch that applies the lock up clutch of the torque converter is defective or a the torque converter itself is defective, the trans pan will need to be removed to check the problem further.

Why is my 1998 Ford Windstar 98 reading DTC P0743?

#1) Low or dirty transmission fluid #2) Wire/circuit issue shorted to power or ground #3) Failed torque converter clutch (TCC) solenoid #4) Failed TCC assembly in the torque converter.....

Since Transmission has been rebuilt I would strongly suspect the TCC solenoid and/or its wiring...When transmission was rebuilt did the TCC get replaced? If so, due to being intermittent, Check the TCC plug (both female and male) for bent or dirty contacts...also insure you have close to zero ohms of resistance from negative battery post to transmission case...A poor ground will cause a problem and be at times...saailer

02 explorer dtc p 0743 and p 0745 and od light flashes how to fix

Code 743 is for a problem with the torque converter clutch or circuit, and code 745 is for a problem with the pressure control solenoid.
Those two components are inside the transmission and would need to be tested by someone with the necessary tools and repair procedures.
