RPM hunting with the cruise on

RPM hunting with the cruise on
I have noticed that my 08 RAM, with a HEMI w/MDS while cruising between 60 and 65 with the cruise on, the rpm will hunt between 1600 and 1900. It is like the converter is locking and unlocking. It does this on flat ground. Does this have something to do with the MDS? It drives me nuts and seems like it would be wasting fuel and lock-up clutch life.
The truck is stock and has about 1100 miles on it.
Thanks,
Jimmy

My Dad and I both have an '07 and they both do it. It doesn't have to be any certain speed, cruise or no cruise. The fella at the dealership said it was the MDS...dropping and/or adding cylinders as needed. I don't know if that's true or not. It sure doesn't seem like it shouldbe doing it, though. Oh well..........

RE: RPM hunting with the cruise on
Mine does the same thing. I had 000 miles on it when I got it and now it has 2000 miles on. it still does the RPM huntingas you call it. I set the cruze at 65 and the rpms bounce around constantly from 1800 to 2000. I just figuerd i was how the MDS system works. If the engine or trani die on me we'll then I guess iLL JUST HAVE TO PUT THE LIFETIME WARRENTY TO WORK.

Hi All,
I've recently purchased an '06 4dr. with HEMI w/mds. I noticed the rpm shift also when the mds went on and off. I don't think the tranny is the problem. I think it's an electrical load difference that effects the tach causing the rpm shift.
