MDS?

[McBroom]

Seconded. I have a '13 6 speed and It's only come on a few times when towing (with tow/haul on) but it definitely does.

Happens mostly going down hill though

Correct. I stand corrected.

After 2012, if the transmission is list as a 645FRE and the vehicle manufacturing date is after Oct 2012, the MDS will not be defeatured in Tow/Haul Mode.

My apologies.

Best regards,
