Normal, 3 to 1 shift. When you downshift, of course the rpms have to go up to match the speed.

Skips 2nd to reduce transmission slam since there's more gears to downshift in such a little time. The reason is the way the one way clutch works. 2009/2010 shifted to 2nd when slowing down, and produced terrible shift slams that felt like you were rear ended.

I had a Mazda B4000 for 17yrs, automatic, it never did what this one is doing. I know there is a world of difference in the 2 trannies. I also had a 91 F150, it was a stick. I have a 2009 Odyssey it is very smooth. I know - again a completely different tranny - Can't compare apples to oranges. My neighborhood has a couple of hills and stops signs, I usually do a rolling stop at these because there is little traffic in the area, the truck almost always does the downshift - then high rev. Based upon your feedback and others I now understand the downshift from 3rd to 1st better - skipping 2nd, although I'm not doing a complete stop. It is the rev back to high rpms without the feeling of forward acceleration - it is just floating. Please review my earlier posts, after reviewing my videos several times I have adjusted the rpms and mph downward for the shift from 3rd to 1st. Thanks again for all the feedback. I'm wanting to learn about this truck and tranny.

I'd suggest that you stop at stop signs since stop signs indicate that the vehicle should stop and not simply slide through. Stopping at a stop sign will stop the transmission symptoms that you are describing. Seems like driver error to me.

I'm trying to be green, save gas, unnecessary tire wear, reduce brake dust and save the planet. As stated in my OP, the issue happens at speed bumps and also rolling up to a traffic light that is red - then turns green b4 I make a complete stop.

It's in 1st gear. Not really seeing the issue here. When in gear the engine is directly connected to the transmission which is in turn connected to the rear end. You can't just change the RPMs the motor is at at a given speed in a given gear.

After reviewing one of my videos several times this is the sequence of events. This is on a slight downhill grade in my neighborhood. The downhill grade is not enough to cause the rpm/mph increase I’m seeing.
My speedo and tack are analog – so there is a little difference in the exact readings/shift points.
At ~ 18-19 mph- 3rd gear ~950 rpm idling along - slight downhill grade
Pressing the brake to slow down (NOT STOP)
As the speed drops below 5 mph – almost to 3, rpm dropping to ~600 it down shifts to 1st,
(I'm fine with that based on feedback - thanks for that info, the tranny skipping 2nd in the downshift is fine.)
Once in 1st gear it immediately starts to rev up, the mph is below 5, closer to 3
The rpms go to 2100, speed goes to 17-18 mph before it shifts to 2nd. (I am not on the gas at this time)
From 600 RPM to 2100 RPM and from 3-4 MPH to 17-18 MPH without me stepping on the gas is where my issue is. I know this is on a slight downhill grade, but it not enough to cause this issue, the downhill grade will cause an increase but with the engine/tranny being under No-load (heavy acceleration) it should shift up to 2nd at around 1000 rpm/10mph
When I do a normal pull out from STOP it shifts fine at around 1k/10mph.

The trucks shift strategy is to use engine compression to assist in slowing down. It does this even more so with tow/haul mode engaged.

have you done the battery discconnect, that will set transmission back to factory default shifts. your truck has an adaptive learning tranny. look at a You Tube video how to correctly drain off the voltage. sounds like the way my wifes Flex acts when i use the hill assist, stays in lower gears and rpms rev up. i do the battery disconnect to my wifes car every 6 months or so and shifts great. seems the way she drives it shifts lazy is the only way to describe it. our 6 speeds are geared really low in first gear, that an drive by wire the trann ymaybe getting confused. while you got battery down, clean the posts and put some no ox on the posts.

Thanks white08gt, this is the type of feedback I'm looking for. It is hard to explain to someone the symptoms via text, it was hard to explain it to my neighbors talking face-2-face, but when I used their vehicle and demonstrated the issue to them they were shocked - they had never noticed. There is some comfort in knowing that 4 other F150's do it, but it just doesn't feel right to me. That is why I joined this forum - to get info, etc about this truck, etc. Thanks again.

if you or your neighbours have an iPhone download the App called Auto MD. I find it's a great app that I have used at the dealership when they give me a song and dance of. " we don't know what is going on". This forum is also a great place as well. Best of luck.
