Alright so swapped transmission, I swapped with an older model transfer case and transmission, it worked fine the stopped . So I took it out and had both my old one and the one other, had both pans off and swapped shift solenoids, neutral safety switch swapped shift linkage holder. Okay, then I put my old back in with these swapped components. I put in fluid, crank it then add until it's at the spot it's supposed to be. Okay, so now I attempt to drive my 4wd button setup won't change from neutral, and the truck won't move, I can hear the clicks when j switch gears but no movement. What do I do?

It sounds like something got stuck in the pressure control solenoid. here is a guide to help see what to look for. We should run the codes as well.

I called just got a bunch of static? The diagrams are the same for 4 or 2wd btw. It could be the transfer case encoder not moving the shifter fork. Here are diagrams showing you what to look for. Check out the diagrams (below). Please let us know what you find.

One more question, inside the encoder is a solenoid with four connectors inside the black plastic housing, can you give me a diagram of that?
