    Hi,
    Yes, he did install the clutch sensor. I came to the cat dealer and they found some wires disconnected. They run from the dash on/off switch to 120pin connector and from there to the ecm. He can't get a signal from the dash to the 120 pin but he has the signal from ecm to 120 connector.

    Yes, he installed the clutch sensor. I brought it at cat dealer and he found some interrupted wires between the on/off switch and the 120 pin connector. Hopefully they can fix it.

    Just an update,
    I fixed both trucks. Apparently there is a problem when you switch from automatic to manual where I had to bypass a wire from the 120pin connector, on the outside of the firewall. There is signal from the ecm to the firewall but it dies once it passes through. One truck I took to the Cat dealer and the other on I did based on the previous one. Still the computer had to be reprogrammed. The On/off switch couldn't be seen on the computer. Once I replaced the wire it works like a charm. To have the wire and ecm done they charged me $650. Hope this helps someone in the future since I've been looking everywhere for this info. Thank you all for your comments.
