I'd bet $5.00 it'll take some sort of programming, that's IF it can even be done at all (kind of like Sierra SLT LED headlights being 0% compatible with non all terrain SLE'S). I mean it probably CAN be done but not without some non OEM modifications.

I have noticed the same thing, or so I think. It's always out of the corner of my eye but I see the needle move slightly.

Your tha man. That's exactly what I was looking for. Since you mentioned it auto dim on the drivers side mirror would be a pretty nice addition.. Starting to regret not getting the slt but I HAD to have a center console... I'm an idiot.

I seem to remember on the gen 3 trucks this was possible but requiring all window switches to be replaced and possibly some BCM programming from the dealer. That was to get the power fold option to work though. Something I dont really care about. What im after is the turn signals in the mirrors for my own piece of mind. 5% tint on the back windows doesnt help when trying to change lanes in traffic and i believe the turn signals in the mirrors would at least let people right next to me (in blind spot usually) know what my intentions are.. Anyways thats why now i need to know how. Ive found replacemnets on Amazon (can't seem to post link) that have two plugs in em. I'm guessing it would take some minor modification but wiring the LED's up to the turn signals can't be that difficult right?

Go to another dealer

Yeah that. Totally agree. Maybe since it is a new truck/engine there will be some future software updates that address this, hopefully. Or a custom tune if all else fails.

Haha sorry Richard, I thought you were complaining about me complaining about my truck. I apologize for being a little kid resorting to name calling. And I see now where transmission replaced transition, thank you for bringing that to my attention. One bad thing about reading text, for me at least, (emails, actual text msg's, posts in forums, etc.) is that it's difficult to pick up on tones. I'll try and not jump to conclusions in the future.

The Cadillac weight thing was a joke by the way. And I came from a 2004 4 speed 5.3L and vowed never to do that equivalent combo again. I wanted a 6 spd 6.2L but found a deal on a new 5.3 that I'm happy with. I'm not complaining about the transmission from V4 to V8 you dick (seamonster) , I'm just curious why a car from 1997 would have a softer switch than a 2014 pickup and if my personal experience is normal. And the answer is apparently no, not everyone has this issue.

Well, seems like it's about half and who do and don't notice it. My grandparents have an older (97ish?) Cadillac that has cylinder deactivation in its "Northstar" V8 and it is absolutely seamless switching between the two. Of course it probably weighs more than these trucks and FWD but still, I would prefer "AFM" to feel more like that. I may take it in and see if there is any fix just because in my mind there shouldn't be any noticeable transition, and for some there isn't. Thanks for the replies guys.

How "seamless" is your AFM? Mine, not so much. Granted this is the first vehicle I've owned with cylinder deactivation, it just doesn't seem right to me. It's honestly like it's downshifting when it goes from V4 to V8 at a hill or gust of headwind. And V8 to V4 isn't much better. There is a very noticeable (but not huge) jerk exactly like the transmission is shifting up or down. Have not tried in manual mode yet but will next time I'm out and about.
