It does disable it as long as you are not in drive. So if you mean it does not permanently you are right, but in order for the mds to work the transmission must be in drive. It will not work in any other position as per owners manual. also if you put it into 6 gear you get all the slipping in and out of different gears but if in 5 gear it will give you full power and and stiff shifts.
