2015 m drive

[Bluebulldog]

Bought a 2015 with a m drive for fall help.  Has 360k miles    Hopefully will last a while.  Question is it has the fleet shift pad.  Has the m but no + or - key.   What would it take to switch to the one with performance mode?   Is it plug and play or need software update.   
 

if you push m should it just go to 1 to start out of a tuff spot with the key pad I have?

The fleet shift pad can be replaced with the performance shifter but a software update has to be done by the dealership. The dealership has to request a software change from corporate. After the software is turned on and installed in the truck, there is a parameter in the settings that needs to be changed as well. There are 3 options for this parameter. One is performance mode turned off , one is performance mode on but will return to economy mode after truck reaches a drop in engine load ( up to cruising speed), the last is performance mode on and will stay on till you turn it off on the shift pad or cycle the key switch. On your fleet shift pad if you hit the “M” manual mode button all this does is hold you in the gear you are in.

I haven’t even had a load on it yet.  But how do we get it to 1 gear to pull out of a tuff stop? Can’t with this shift pad???    It was originally part of the cvs fleet so it probably never seen anything it asphalt.   What’s the astric do nothing?

The * is for some kind of “ Limp Home” mode if you have certain transmission fault codes. I’ve never seen it used.
