Chrysler put the MDS feature on the Challenger, just like autostick is a feature. I'm not going to "disarm" a feature because of a potential failure.
This makes no sense 19john. I own a 2011 rt auto and if there's something I can do to prevent this I will. My luck the car will blow 1 mile over warranty then I'm screwed.
I understand what you're saying racindemon, but not using the MDS has no "guarantee" of how many more miles I'll get out of the timing chain system.
My PCM is a virgin, no updates, canned tunes, etc. In town/cruising around, autostick does what it does well. On the road, the MDS does what it does well. I've figured that I get 2-3 mpg more with the MDS "on".
I feel that "disabling" the MDS is just giving Chrysler a "pass" on this issue, and I'm not going to have them say that because I tuned the PCM with whatever, their failure is MY PROBLEM. Ain't going to happen.
If we knew that the tranny would fail by using the autostick mode, would you disable or not use that feature??? Not me..................it's a feature on the Challenger that was designed into the drivetrain, just like the MDS is, and just like the timing chain components are.
It's part of the design/marketing/sales pitch of Chrysler, and many 5.7 auto owners are having failures that deem the car "inoperable" for some lengthy periods of time.
This is NOT ACCEPTABLE Chysler.
Like I posted earlier, if Chysler would come out and say that MDS+Challengers don't mix, then put the "six speed" motor in. I wouldn't have a problem with that. If they issued new components that were tested not to fail, and installed them through a recall, I wouldn't have a problem with that.
Playing the "legal eagle" stand of "say nothing, admit nothing, and fix what fails".....................I have a PROBLEM with that.
