I replaced my transmission and after putting it in and the transfer case I cannot shift out of first gear in my speedometer doesn't work. I don't think I have the connections on my transfer case right and I cannot find a color-coded diagram of where all the wires and connections go.

Hi,

Do you mean the gear indicator won't move from 1st gear (low)?

I attached the wiring schematic below for the transmission. Let me know if that is what you need or if there is something other.

Take care and let me know what I can do to help.

See pics below. Note: I had to cut the schematic in half to make it readable for you. I did overlap them so you can follow from one to the next.
