Paddle Shifters & the L99- Help

Ok so i was wondering if some one could elaberate and or answer a few what maybe stupid questions I had in reguards to the paddle shifting for the 2010 L99.

1) I have heard there will be a "mode" you have to be in such as "m" on the shifter. Can you go in and out of this while driving or only while stopped?

EXAMPLE: for instance... if you where driving... say 30mph and you wanted to activate this "mode" how would you go about shifting up to third while in motion? My thought is if you must shift up to third through the paddles... wouldnt the car enage into first and second (while your driving) as you make your shifts?

2) Will there be a paddle to downshift or will the car auto down shift for you (as I heard some cars do)?

Also i have a general "?" about the L99 system and its AFM system
I heard that this entitles the car using less cylinders when not needed? and if true wouldnt this promote uneven engine wear?

Yes. And to get out of manual mode, you shift back to 'D'.
It sort of works along the same lines as shifting into 3,2, or 1. ('I', and 'L' on some) on a conventional Auto. Except there's no gear changes when you click the shifter down on this one. It just turns on alternate programming: The 'sport' mode.

the afm shuts down 4 cylinders, then after 9 min(i think) it fires them back up then alternates which cylinders are shut down

Really? Wow thats really interesting. My dads impala ss has this feature and i always wondered if its the same cylinders that deactivate. I thought to myself wouldnt those cylinders wear more than the others. This makes much more sense.

wrong, it is always the same cylinders that are shut down when afm/dod kicks in:

straight from the gm service manual:

To provide maximum fuel economy under light load driving conditions, the engine control module (ECM) will command the cylinder deactivation system ON to deactivate engine cylinders 1, 7, 6, and 4, switching to a V4 mode. The engine will operate on 8 cylinders or V8 mode, during engine starting, engine idling, and medium to heavy throttle applications

Is this the case with all AFM engines? Does GM do anything to add protection to those cylinders?

What protection would be needed?

I figured there would be some sort of warranty or physical protection of the cylinders. I guess they aren't really likely to shoot out of the hood because they'll be hitting at substantially less RPM than usual. I was just wondering if GM designed AFM in such a way that it would need no maintenance of shop support.

They did...that's how it works...I guess I'm not following you...

When AFM is on -- the valvetrain, spark, and fuel for the dedicated cylinders are shut down. But the pistons themselves still move up and down like normal. There's no increased load, or extra wear that would require an extra warranty, or some sort of protection.
