Obd codes shows incorrect ratio for gears two and three. There is difficulty to get to gear two. I was told to change the neutral safety switch. I got a used one. Still gives problems unable to pass inspection. Help.

Hello,

There is a transmission speed sensor that goes out on these cars, here is a wiring diagram to show you which wires are going to it. I would try replacing the sensor and then clearing the codes. Check out the diagrams (Below). Please let us know what happens.
