Now let ME correct YOU.

Cbvet had a Lariat with the 4A, and he knows of several other Platinum models with the 4A that can do it too.

Mine is one of them. Cbvet and I have pretty much determined that only the '11 and '12 models with the Auto4wd will shift out of 4wd under a load. The newer trucks, even with the auto 4wd will not shift out. Mine will do it stock and tuned, no difference.

I thought mine did too (shift to 2 under load). The indicator on dash says it does. But in fact it doesn't. The actual disengage happens when you let off the throttle.

Default Stop wasting our time.

Stop all your ignorant arguements on a thread they aren't meant for. Go make your own thread like the others for this bickering that the rest of us that don't care won't have to see. This is very annoying to keep getting alerted for your bickering. Put up a new Timeslip or shut up.

Mine actually does, you can feel it shift out. And I get almost 3 mph higher trap speed when I do versus leaving it in.

Lmao, your a piece of work, don't say you know for a fact because you don't, I raced my truck too, check the times, so that has nothing to do with it. Yes it did shift out of 4wd under a load at any given time, you can physically feel it shift out every time. It's not my first rodeo with a vehicle and I know when a truck is doing it, my 13 fx4 wouldn't do it and I was so pissed after I bought it. Here is a video of me doing a boost launch in 4wd (watch the rpms on the torque app) also it's not barking the tires in 4wd.

Nothing ignorant. And far from bickering. Were helping each other understand something that's relevant to quarter mile times. So, why don't YOU shut up and read on.

4wd to 2wd under load - YouTube

Re-read my comments. I said I am speaking for my truck. At first I said none will because mine won't, And doesn't shift under WOT into 2wd. I have sct tuning. Maybe something about that prevents it? I wish it would. But my truck won't
