Question

I have a code P0750 in my 2002 ford F150. Currently it want back up and the overdrive light stay on

Answer 1

the problem is inside the valve body of the transmission, if you have not replaced your transmission fluid in the last 30k miles you should start there or take it to a transmission specialist

Possible causes

- Low transmission fluid level

- Dirty transmission fluid

- Faulty shift solenoid 'A' valve

- Shift solenoid 'A' valve harness or connectors

- Shift solenoid 'A' valve circuit is open or shorted
