Answer 1

P0740 Torque convertor clutch (TCC) no RPM drop at lock up

This condition if you have to shut down and do a restart and resume , this is more of a hydraulic internal transmission problem than a solenoid or sensor .You can change the transmission filter and add a transmission additive that will help thicken the the transmission oil , see if that helps.
