I have an '05 LJR with the 6 speed manual and the PCM started acted up while I was 6 hours or so from home in Moab. I think it had maybe 120K on it at the time. It was stalling and sometimes not restarting right away. The gauges were dropping out and coming back. I knew from posts on this forum that the symptoms were pointing to a PCM issue. After reseating the connectors, it started behaving but I figured I was on borrowed time and might not make it home.
While waiting for a group ahead of me on Top of the World, I called Mark at Wrangler Fix. He pretty much confirmed that my PCM was on its way out. So I talked to a guide with a commercial group on the trail and got the OK to have a PCM shipped to their address in Moab. After ordering a new PCM from Mark, I completed Top of the World where my profile pic was taken and also won ROTY!
Meanwhile, Mark took a PCM off the shelf, tested it in his Jeep, then overnight shipped it to me in Moab. I picked it up the next day at one of the local Moab businesses. I didn't need to install the new PCM on the trip and made it home OK. I think an extremely cold night in Moab might have triggered my PCM issues. Regardless, I installed the new WF PCM shortly after getting home and it's been working flawlessly for years since then.
I used to think only the PCMs in auto trans vehicles had issues. Not so.
If you need a PCM, get one from Mark.
