ACD Shifter Lost CO2 Instantaneously

[David Daulton]

My ACD three speed shifter did the exact same thing once and it ended up being the push in hose connector at the 2-3 solenoid. The sealing ring inside it cracked/blew apart. I replaced all of them with some higher quality ones.

Thanks again to all of you, guys. I think David got me onto something. This past weekend, after disconnecting my harnesses, I for some reason started laying the right-side lap belt across the top of the nylon lines that feed air to the shift solenoids. Before one run, the latch mechanism kinda caught on one of the lines, and I'll bet when I pulled on it a little to free it, I displaced or cracked something. It's really cool how this forum can help a guy solve a problem; the experiences of others stimulate a person's mind.
