Hi everyone, I just wanted to share the way I disable my MDS,it doesn't disable it permanently, u have to do the same procedure everytime you put it in drive but it's not to much of a issue. When I put my truck in drive I hit the gear '- button then you will see your gear selection show up by the D in your instrument cluster,then I hit the gear + button until my gear selection number reaches 8 and that's it. Your transmission shifts just like normal but the MDS does not operate. I have also noticed that since I've been doing this I haven't heard my lifters clatter in the morning when I first start my truck, whether it has anything to do with that I'm not sure,just sharing my experience.

 

or press the tow/haul button.

 

I tried that but my eco light will still come on.

 

what trans do you have?
