I've owned my 2015 4x4 screw for 2 months and I love it. But I hate the lag when shifting from reverse to drive and I'm surprised no one else has mentioned it. It is so severe, it feels like the truck is going to stall. I've never had a truck do this. Has anyone else noticed?

The best thing to do is take it to the dealer.

ISSUE
Some 2011-2014 Expedition, Mustang, F-150 and Navigator vehicles may exhibit a delayed park to forward or reverse
transmission engagement only on initial vehicle start up after parking several hours or overnight. The vehicle functions
normally after the initial engagement has completed.

Replace transmission pump assembly

I just had this done on my 2013, got it back last night so still too early to tell if its resolved. Your description sounds very similar to mine and it's essentially the same powertrains so I'd assume it would apply to your 2015.

I thought it was just the way the truck was... I'll have to decide if I need he transmission pump replaced now

My truck does this also. There is a good 2-3 sec delay when shifting from reverse to drive. The trans can be warm or cold, same result. I back into my spot (slight decline). Got a little close to the wall so decide to pull forward a tad. Foot on brake, shift to drive, release brake, apply gas truck rolls back for a sec or two, then moves forward. Anyone been to the dealership yet? Fix?

Did you ever take your truck to the dealer? Did they fix this issue? Thanks.

Mine does this as well.

I mentioned it to the dealer twice now. It has been brought to my attention that there is nothing they can do for it, and this is normal function.

meanwhile, I am left with "stranded in the middle of the road as I back out of my driveway" shift situation.

This may seem like a stupid question but I'm just trying to help here.

Are your driveways on any kind of an angle? The reason I ask is that I only have this issue on my driveway and it's due to the hill assist brake feature.

I have a side-apron on my driveway on which my truck is parked. My drive is on an ever so slight uphill, as most driveways are. When I leave in the morning, I actually need to pull forward about 3 feet before Turning and backing off the apron. When I put the truck in drive, and let off the brake, there's a few second delay before the truck starts creeping forward on its own at idle. I first thought there a transmission delay but then figured out it was the hill assist. When I park at work and go into drive, there is no hesitation, as it is level. Also when I back into my driveway and go into drive to leave, there is no delay. I imagine if I back onto the driveway and then try and back again some more in reverse, I would get the same delay, as I think the hill assist is also supposed to work in reverse.

This may be a long shot, but hopefully it may be an explanation.

First day i had mine i was a bit confused as to what was going on when i had to stop on a steep hill.
I figured out that was why and actually it is a nice feature in many ways once you get used to it.
Considering how many people do not use their brakes to come to a complete stop before going from drive to reverse, or reverse to drive and make rhe transmission stop it and change direction....i would not blame all auto makers for building in a huge delay on purpose.

I've noticed this as well, kind of annoying. Trans ends up slipping bad if you get on the throttle too early. Hot, cold, flat, incline, doesn't seem to matter.
