I've done some searching and found alot of threads for older model trucks having this problem but only found 1 or 2 for the new aluminum body trucks. My truck is a 2017 5.0 with 6 speed and 4x4.

The other day I was moving some pieces of tree limbs to burn and I noticed that shifting to drive felt like it took a while to feel it engage but I was on an incline so I didn't sweat it much.

This morning I was running a couple minutes later than i like to leave for work so I put it in reverse and it felt fine backed up, came to a complete stop and swapped to drive a little faster than normal, mine has a column shifter so it's not like I was speed shifting, and gave it some gas. It revved for a second or two and then wham dropped into gear. I'm pretty sure that's bad for the transmission it drove fine all the way to work but I wouldn't expect that much delay from a truck with 4k miles in shifting.....

I read some people say the dealer told them this is normal but other people respond saying it isnt. I saw a tsb about fluid pumps but I don't think it applied to the brand new trucks. Ive got 100k mile warranty but i would prefer to not break down....

My truck is a 4wd and I haven't noticed it until the other day when I moved those tree limbs I didn't want to tear any grass up so I put it in 4wd so if it did sink it wouldn't spin in 2wd and leave ruts.

 

That does not sound normal to me. Such a long delay before gear engagement is a problem.

 

So how much time are we talking? Perhaps take a stop watch and see. Then go to dealer with that info. Is this just a cold start thing as well?
I would say mine is slower than I would prefer but all my vehcles have been that way since being electr controlled.

 

Long enough for me to hit the gas and not move then feel it drop into gear. I'll try and time it. When I was moving the tree it was cold I only pulled the truck from the front yard to the back yard and killed it when I got to either location. This morning it was cold for sure hasn't moved it since yesterday afternoon. When I made it to work I tried to shift again and I didn't feel the delay but I wasn't pushing the gas for fear of damaging the transmission dropping it into gear under rpms.

I got rid of a 2002 f250 and a 2009 Ford ranger so maybe they were mechanical linkage and I'm just not used to electronic delay either?

 

On a cold start mine will take a second or 2 to shift into gear. I've just learned to wait. It's electronically controlled so certain conditions need to be met before the computer sends the signal to the actuators and then they have to do their job. I've shifted then immediately hit the gas and experienced the same thing. Not just in my truck but also my ex-wife's 4Runner and my old Xterra. Let it shift.

 

Was this very first thing in the morning on a cold start? I've experienced the same thing when I've been in a hurry and failed to remote start the truck.

I'd probably monitor it for awhile and see what happens. The transmission is adaptive and there's lots of computer smarts going on. These transmissions are also "quirky" so to speak... the old 4R70W/E4OD/4R100 slushboxes didn't have much character because they were so sloppy (but reliable). The 5Rs and 6Rs are much tighter, but this tends to reveal more odd behavior. For instance, despite multiple dealership trips, I still have a fairly hard (though less so now) 5-4 downshift... which seems to be commonplace.
