Transmission not engaging. The truck does not move. I have replaced the output speed sensor. No difference. I am looking for the input speed sensor so I may replace it.

I don't think the input shaft sensor will help but you never know, is the transmission full? This guide can help, and I have included the location for the input shaft speed sensor as well.

You will need to lower the transmission to access the sensor. I included both output and input sensors. Check out the images (below). Please let us know what happens.
