Thanks all. I decided to go the easy route that Bob suggested. I unplugged the communication wire from the monitor and that did it. If it comes up again I'll try Tom's suggestion. And thanks Frank for the link to the manuals. My manual only goes to page 9. :-)

I had the coach in for some repairs on the cabin a/c and investigating why the generator would not start. They fixed the a/c was and determined that the generator needed a propane regulator replacement. When I got the coach back, the monitor seems to be a little confused, as shown in the attached picture. Any thoughts what may be causing this? It is currently plugged into 120v.

The one inside of the transmission. It sits in the transmission fluid pan. It has a wiring harness that travels out of the pan and into a control board. I had the sensor and wiring harness replaced.

Had a similar problem a couple of years ago with my 99 Diplomat. It turned out to be the fluid level sensor died. Had it replaced and no more issues.

Had a similar issue two years ago. Mine would also stop while driving and everything shut off. That was exciting. I replaced the ignition switch, ignition solenoid and fuses. Don't know for sure what the issue was, but one of these items fixed it and they were cheap. I strongly suspect it was the ignition switch and it was pretty simply to swap out.

Just returned from a 500 mile trip without any issues with the coach dying. I replaced the ignition switch, ignition solenoid and fuses. Don't know for sure what the issue was, but one of these items fixed it and they were cheap. Thanks for everyone's input and advise. Bill

I had the same problem when I switch out my couch with recliners. I bolted office chair roller to the front of the frame of the recliners. I'm going to redo the floors this year so may extend the platform for the chairs then.

Thanks Pat Sorry I picked the wrong name for that question I think I'll replace the solenoid and the ignition since they are both relativity inexpensive vs having a shop troubleshoot and correct. I may still wind up there but it's worth a shot.

dl_racing427 I think I'll just replace it, since it is a intermittent issue. I can only find 120-150851 part number vs. 120-105851-6. Do you know if there is any difference? Thanks

That makes sense. Thanks

Bingo! Found them. Thanks Pat C Next question How do I determine which one is for the ignition? Here's a picture of the setup. Unfortunately I can not remove the covering all the way at this point since they decided to run a ground wire through the plastic cover. I need to figure our where it's attached or cut it and put a wire nut on it.

I've been looking for the solenoid for the ignition switch but haven't located it. Does anyone happen to know where it is on a 99 Diplomat? Thanks

No bypass to the issue that I found As far a I know it lasted 22 years. It is convenient vs having to unload everything from under the bed to get to the dip stick.

Thank for the suggestion Also trying to find the solenoid for the ignition switch but not successful so far.

I have the Allison MD3060 transmission. He drained the fluid, removed the filters, unbolted the bottom of the transmission, dropped the bottom out, removed the oil level sensor, compared the old one with the new one and determined the new one was not correct and order another new one. Once he had the replacement, replaced the oil level sensor and wiring harness, bolted the bottom of the transmission back into place, insert the filters and filled it up. It appeared to be a fairly straight forward process, as long as you have the right parts. Below is a picture of the bottom of the transmission sitting on my garage floor waiting for the right part. Cost to replace, with two trips out to my place, was $1,403, which includes $880 of parts.
