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.

Thanks!

Thanks Ivan! Is yours in the FRB? I just check mine and didn't see it. Wonder if it is under the dash somewhere.

Got it Thanks! And when you mention solenoid/relays are you talking about the small black cube relays in the same box as the fuses?

Just to wrap this topic up. I did find a shop in Chehalis, WA that could do the work. Great service, Transmission Unlimited. Owner volunteered to come out and do the work in my driveway. It is now fixed w/ a new oil level sensor, wiring harness, fluid change and new filters. Thanks everyone for the suggestions!

I'm sure I should know this but what is a FRB?

Everything helps! I do not know But doing a Web search, it doesn't sound like I should be hearing any clicks when I turn the ignition on or maybe just one. I hear 3-4 rapid clicks. They sound like they are coming from the dash somewhere.

Another wrinkle. I thought I saw this last night on the side of the road and saw it again today. If it is not working (dead) and I leave the ignition in the on position, the dash comes back to life after a couple of minutes and I can start the engine.

Last trip it was the Oil Level Sensor issue. Got that fixed. This time went to change sites at the campground. Turn the key on and nothing. Backup camera turned on but nothing else on the dash. Sat there for a few minutes staring off into space trying to come up with a good explanation, tried it again and everything worked. Upon leaving the campground to come home, same thing again. On the trip home after about 125 miles the coach shut itself off. Luckily, I was on a straight road and was able to coast to a stop, blocking traffic. After 5 minutes or so it started again. Drove 50 miles and I shut it off and it did it again but was able to get it going again. Another 35 miles and it shut itself off again. Was able to get to the shoulder out of the way this time. Arranged a tow from Coach Net. After about four hours it started again and drove the last 80 miles home. It has been suggested that it could be the batteries or a relay switch. Appreciate any thoughts or suggestions. Thanks!

Agreed I think I'll try cleaning contacts that someone suggested on IRV2 and see if that solves the problem. I would think, and maybe I'm all wet, that a sensor would go out and stay out where as a connector could fade in and out. It has shifted into gear without issues for the last three days sitting in my driveway.

Thanks for all the info. From all I've read, it appears to be mounted internally. I was looking for some recommendations for local service from personal experience. I have a couple in mind and will contact them today. I have tested putting it in gear since I got back and it works every other day. I think I'd rather have it not work at all than just sometimes. Thanks again
