Electric motor sound when first put into drive

What is that sound? It only does it when I put the truck is put into drive and start to pull out.

Ever been on an airplane and hear the motors working in the wings to adjust the air flaps? That is what it sounds like but only for 1 second.

 

I don't remember what it is, but it's normal.

 

I have a similar thing on an 09 6spd. It sounds very much like the auto door locks on some vehicles. On mine it sounds like it is above and behind me - Something in the seat belt mechs. maybe ?

 

I figured it was normal. I think it sounds pretty cool, actually. Like a jet preparing for lift off


Curiosity is asking what the truck is actually doing.

 

If I remember correctly its your ABS system doing a self check.

Thanks, that answers the same question that I had, but was not going to ask....
