I have 2018 3500 with manual transmission / transfer case. I get a "4WD Shift in Process" message flash fairly often. If I "nudge" the stick it sometimes goes away. Or sometimes when I engage Cruise or Exhaust Brake the message doesn't come back. I'm thinking that there is a 4WD position sensor somewhere that has intermittent failure? Being a manual, I don't worry about it self-shifting, but it's pretty annoying. Any thoughts?

first thing i would do is make sure the linkage is adjusted correct and put dielectric grease on the harness going to the cad motor. if you still get shift in progress message then yes it may be the position sensor

I'm pretty sure this is prevalent in many 4WD Rams, especially the Power Wagon. I'm not a proponent of throwing parts at a problem, but in another board forum the solution was replace the Transfer Case Position Sensor (TCPS). It's in an awkward position on the Transfer Case (TC). I replaced it and the message has not reappeared. I assume your 3500 has the BW 44-47 TC, so the TCPS is located above the boss for the shift linkage lever, driver side of TC. MOPAR Part # 68211454AA. If it's a 44-46 then I cannot speak to it. The sensor must be in shift motor or the mode sensor.

Yep, like seppw stated and showed, that is your issue for sure. Pretty common. I just had mine replaced because I was getting the same message intermittently. Has not come back since.

pretty common ? going back 1year in the gen4 Hd section theres this thread and one other possible tcps related thread. i recall atleast 1 for sure , maybe 2 threads not long ago in the PW section. how does that even get close to equalling common ?
if you want to know what common is, death wobble on them new fords. there was over 60 threads as of 8months ago.

The part is under $60 i think. I frikin paid a $100 deductible to use my lifetime warranty for it to get fixed at the dealer ugh.

your dillusional without any doubt what so ever. maybe stick to something your familiar with like leveling spacers or something

Well mine does it from time to time... I just don't post every mundane detail of the truck on the interwebs... I'm sure many others don't post every little issue as well... Death wobble isn't a little issue, so I would expect more noise on the subject.
