Weird moan/groan/vibration/friction

Well I've only put about 500 miles on my SRT thus far but have to share a weird symptom (just as the title reads). It seems to occur while at speed, and it comes and goes literally every 20-30 seconds. It seems from the rear of the truck, starts quiet, grows louder, and finally releases and goes away. It almost feels like it's resisting the drive train before it 'let's go'

Anyone else experience anything similar?

The only thing that i can fathom at this point would be if you are referring to the MDS system. Just for kicks, drive it in sport mode and see if you can still reproduce this phenomenon.

Switching to sport seemed to make it stop. So is this normal? Seems odd and quite annoying to me.

This is normal and I think the poster above is right. using paddle shifters will also disable MDS.

Do a search on "MDS drone" to learn all about this wondrous doodad of a function. There is a good chance that these new tuning units (i.e. Trinity) will be able to defeat this IMO annoying feature. Anybody care to toe in on this?

Re: Weird moan/groan/vibration/friction

It is loud on the srt. I was already used to it from a 5.7 commander but the 6.4 will run four cylinder mode even at 80 on the interstate so it's constantly off and on depending
on the needed horsepower or load. With the eco turned on it runs four banger mode even more often. Nice feature if i could keep mine out of sport mode. lol
