I did a quick search and came up empty-handed so I'll let someone else address this, but we're going round and round as it's come up before. People have asked their dealers, have been turned down, and MDS has been deemed part of the whole CAFE-compliance thing that's too hard to turn back, however you put it. I have little interest in the specifics but some here are on top of it and will certainly chime in. You're right that AutoStick shuts it down (although I'm not sure it's 100%), and I never understood how they let us have that, but driving pedal to the metal is also a MDS-disabling technique that they can't take away.

ETA: my post was in response to sean65 as StoneCold pulled the trigger faster!

MDS has nothing to do with CAFE standards or emissions. If it did, the 6 speeds would have it to. MDS is there for the fuel savings only, as the automatics have a terrible final drive gear ratio. What would have been a nice feature is just having a push button for "eco" mode or not.

By the way, MDS is either enabled or it's not, there is no in between when using auto-stick. If people are that freaked out, pull the solenoid wiring connector. You'll probably get the CEL though when MDS tries to kick in.

My bad: all the green stuff makes me see red and I can't pay attention so I lump it all together. And yes, people have pulled the plug themselves here and gotten several codes, if I'm not mistaken, which few of us want to deal with. These asides distract from the discussion that dealers don't disable that stuff, though. AutoStick, Trinity, Predator... it's a free country. I just find it annoying that at this point, although there is no hard evidence one way or another, some (in general) post absolute statements about the TC risks.

I know it is early still... but have any of the new '13's had any issues yet? Perhaps some mods were addressed for this model year? I am curious since I just got my RTC about 5 weeks ago.

The timing chain on my 2010 Auto RT broke last Friday, ~40,000 miles. I was traveling on the highway in the left lane, the car slowly started shutting down and completely died once I got to the shoulder.

It was enabled, but I'm not positive if it was on at the time or not. I had been at a cruising highway speed so it probably was though.
