Well it means many look at the side of the shifter do you see a pluss and a negative there yes put it in m then auto shift with the pluss and negative use the gas like you are ramping up it will move way faster quicker too have fun with it

M mode is kind of like locking out gears but worse IMO. Say you start from a stop so you're in 1. You have to manually increment the gears else you will rev really really high before the truck does it for you. Now say you're towing up a hill and want to stay in 4th, it will do this but if your RPMs drops below the threshold where your truck would normally shift to 3 then this will happen and the M setting will drop to 3. Now you have to manually increment it to 4 again once you have enough RPMs
Better to just lock out 10-5 to target 4, and should your RPMs dictate you fall to 3 then let the truck shift back to 4th instead of having to manually do it. That's the only real difference.

Most folks that have never driven a manual transmission do not realize that the computer is reacting to changes in the environment, direction , speed and grade. It is a delayed reaction. The computer can not anticipate and prepare for a 6% grade, or downshift prior to a 15 mph hair pin turn. It's why drivers get frustrated with the throttle lag and required input to the throttle to get the needed downshift after making a sharp turn. By taking control of the shifter you eliminate much of the complaints about modern transmission protocol.

M mode means Manual, which means you have to manually shift. Only difference is, since it's not real manual transmission, it'll auto upshift so you don't bounce off the rev limiter or downshift so you don't stall if you don't do it manually before that happens.
