That will get the trans and engine working together, shifting.
Then use the vss output wire from the PCM to the speedometer.

Ive had the truck running for almost 2 years now, and just dealt with the issue. But now Im ready to dig into it. I called a long time ago and I think I spoke with Ray about connecting your vss connector (new style) to my old transfercase. Since the 2 have different plugs, He said cut my OBS pigtail off and put it on the nelson harness. Was that correct? Thats what I did, but it never solved the problem, and I kind of just forgot about it.Originally Posted by farmtruc

Ya that should work. Should be the same type of sensor just different looking.
Any dtc's?
Like wrong gear ratio or input signal?

The only code I get is Vehicle Speed sensor circuit. Cant remember the number.
I plugged nelsons vss in the back of the tcase and it will shift by itself, but then my speedo doesnt work

Where do you have the speedo wire tied in? On my 1994 I originally hooked it in before the drac/buffer, and it wouldnt read correct. I bypassed it and went straight into the cluster bypassing the drac/buffer and it worked great ever since. I sold the truck to my friend or I would go get the wire color.
Speedo wire should come from the PCM. The VSS wires go to the PCM and the PCM processes that info and sends the signal directly to the speedo on another wire. Should be a dark green/white wire from pin 50 of C-2 connector(Red or Green,depending on year).
