Sounds to me that if you don't hear anything, your solenoid isn't working. It's probably jammed. Unless you're not pulling the codes correctly, it seems probable that you have a mechanical problem with the valve body. Somebody mentioned that they had a problem that seemed to be a valve getting jammed shut by hydraulic pressure. When the engines starts, the solenoid is activated and the valve it controls is exposed to hydraulic pressure. If it's not activated when the hydraulic pressure is generated for the first time, it may not jam. (I realize this is not consistent with the noise test.) Perhaps if you cut the wire that controls the solenoid, it may suddenly begin functioning if it un-jams itself. This is kind of a long shot, but it's a place to begin.

You can also tap into the wiring harness and check for continuity of the solenoid, but if you have no codes, it's probably good. Doesn't hurt to check though.

UberRoo,
How would I "cut the wire"? I thought the wire for Solenoid C was actually inside the transfer case. Would flushing the trans possibly "unstick" the solenoid?
