Went to roadtest the F150 and experienced a shudder and lack of power. Transmission Fault at dash and CEL. Codes recovered: PO731, PO750 and PO753. Traced to a failed Shift Solenoid A. Showed 20 megaohms instead of between 20-30 ohms. Shift Solenoid B was supposed to be same ohms and read at 27 ohms. Torque Converter Clutch solenoid spec is between 10-16 ohms and measured at 15 ohms. Talked to transmission rebuilder and explained that if going to reuse electrical component, should test it. They did not. Gonna go ahead and install all 3 solenoids on Monday and roadtest again. Everything else shows fine with no leaks. My neighbor/customer is all good.
