Having worked in multiple dealers as a service tech and a writer 9 times out of 10 a pcm will not fix a concern. I agree with ford that its not a pcm. Also sounds like your comparing apples to oranges with comparing it to your oddessey. The new f150 shifts very differnt due to there is six gears so the computer has so many options when your are driving along with hundreds of inputs. What this sounds like it's your driving habit. At that certant rpm and speed with throttle input the vehicle doesnt know what to do as it can't be in third grear and second it would bog down so it goes into first and takes away throttle to not allow the vehcile to rev really high and jerk like a manual trans.

Change your driving style and just drive the truck. This is a great case of where you pick up in something and dont let it go. It soumds normal espically that the other trucks did it and I find it really hard to believe yhat they would also have bad thrttle bofs or a bad pcm. Just drive the truck and enjoy it, its the best half ton out there to own.

TSB 13-8-10 might fix the problem. I've been doing some reading deep in the archives of the web. Look up this TSB. It will at least give you the latest transmission RPM calibration, as that might be the issue. As far as going from 3 to 2 good luck. I'm sure you'll likely have to do it manually.

How do you get your RPM's to 2000 while driving 3-5 Mph. I can only do this if I continue to press the manual downshift until it drops into 1st I'm certainly going faster and am on a steeper grade. I agree that there will be an increase in RPM but 2000 as Lee and the video have it. Seems abnormal.

did you do the battery disconnect, sets it back to factory defaults. for a better description my wifes tranny get what i call lazy shifts. about every 6 months a disconnect the battery clean the post and drain off the stored voltage. shifts like new again. her car is 2009 Flex w/6 spd and 99k miles, still runs great and uses no oil.

If the shifting gets lazy she is probably driving it like a granny.

I mentioned in the first paragraph of my OP the truck has done this since I got it at 33k miles. To go into more detail, when I picked up the truck I drove approximately 120 miles interstate hwy, got off drove about 4 miles to my subdivision, it did it at the at the first stop sign. This was the first place in the 124 miles where I had a slow & roll condition. Maybe it learned its bad habits from the previous owner. Maybe my driving is the same as the previous owner. Surely there in no clone of me?

My driving habits are basically conservative.When I drive I am fuel conscious, no jack-rabbit starts, never hard on the brakes. I rarely accelerate fast; maybe once or twice in every 5-6 times I have it out, just to clean it out a little. It's a truck-not a sports car-I have one of those and a couple of bikes to play with. My previous truck last me 17yrs/190k miles, I hope this one does. Should I change my driving habits by doing jack-rabbit starts, winding the engine out until it gets to 4th gear, do hard excessive braking, approach stop signs/traffic lights at a high rate of speed, then suddenly decelerate?

Back on 9/26, post#12, I mentioned that comparing the Odyssey and F150 was like comparing apples to oranges. I am well aware of the differences in what these vehicles/trannys were designed to do. The Odyssey has a 5-speed and is geared different - Gear Ratios: 1st: 2.697, 2nd: 1.606, 3rd: 1.071, the truck is 1st: 4.17, 2nd: 2.34, 3rd: 1.52. Just a simple look at the gear ratios would indicate a difference, all other things being equal. One of the things I don’t know about the Odyssey is whether or not it downshifts to 1st. There is no gear indicator-just the big “D”. I know it never revs up at the intersection I'm referring to in my thread. Notice that 1st in the OD is very close to 2nd in the truck.

On 10/1 post# 64 I pointed out the obvious - the question of 8 out of 8 trucks having bad throttle bodies – seems strange. The other trucks I have personally driven that have this issue aren't as prominent as mine, their rpm increase is about 70-80% of what mine is. Also, I only did a couple of test slow & rolls, I've done probably a 1000 with my truck. Only 2 trucks (my neighbors) have I tested at the same intersection as mine - the place where the videos where taken. As I remember both went from ~600rpm to approximately 1700-1800rpm. Without video I can't tell you much more about it.

It’s hard to just drive the truck and enjoy it when every time I leave my house within 300yds I have to deal with the high rpm issue – twice, then when I return home I’m reminded of it twice. Plus who knows how many times while I'm out "enjoying" my ride.

One would think that since the trucks are so smart and anticipative of what the driver is doing/going to do that it would know where the intersections are in my neighborhood - it would know that I rarely stop, it should know by now that 2000-2500 rpms isn't needed, that a nice downshift to 2nd would be just fine.

The new f150 shifts very different due to there are six gears so the computer has so many options when you are driving along with hundreds of inputs.

I guess that one of the options left out of the program code is the option to downshift to 2nd if not at a complete stop, while rolling on a slight downgrade with little/to no load. I have my reservations about the pcm preventing the engine from going into a stall condition as some have mentioned.

I'm doing it tonight, I disconnected the battery about 9pm, will re-connect it in the morning - go for a short test drive.

Lee 2012 F150 XLT

Bill, thanks I will be looking into this when I get time.

Lee 2012 F150 XLT

I see this all the time with mine, after it has shifted to 1st, slowly maneuvering around in a parking lot - it will go from 600 to 1000-1100. I think others have mentioned the pcm preventing a stall - I've never experienced an auto-tranny stalling the motor. ??? They simply quit pulling but the motor never stalls.

When considering some of the feedback, I have learned that I have bad driving habits, I fake videos, I lie and I have a perfectly normal truck. You guys really know how to treat a newbie.

I want everyone to know that I would not have joined this forum or started this thread without considering all the outside factors (other than the truck) as possibilities for causing the high rpm increase. I have had over a year and 13k miles to consider such factors as the slopes, downhill grades, engine braking, etc. where this is occurring and how often. It happens pulling off the road into a gas station area where there is a slope, I’ve almost stopped on the road, then ease into the gas station area with a downgrade, and the rpms go up just coasting to the pump. It seems that some choose to ignore the fact that this truck does this in level parking lots – with no slope – no downhill grades – when it downshifts from 3rd to 1st, at 3-4mph. WHY DOES IT NEED ENGINE BRAKING UNDER THIS CIRCUMSTANCE? It has happened literally thousands of times under similar circumstances, not just at my intersection.Why does it need 1st gear, when 2nd would do just fine?

Based upon my experience and after reviewing the videos several times, I believe the issue is with the downshift from 3rd to 1st, the video with the downshift from 2nd to 1st was as identical as I could make it, and the problem of the rev up was not there.

In my OP I mentioned that there was no sensation of the truck pulling forward or an increase in momentum during the rpm increase. I want to also add that when it downshifts from 3rd to 1st, it is smooth and there is no “head bobble” effect as when downshifting a standard to a lower gear and releasing the clutch. It simply downshifts smoothly, then after about a second the rpms go up. When cruising the parking lots at Wally World and the down shift happens, the only way to notice it is hearing/feeling the motor rev or seeing the tach.It is like the tranny goes into “limbo mode”, coasting or freewheeling. What is happening to my tranny while this is happening, in the past it was known as “slipping” and it wasn’t good for the tranny. What about the longevity of the tranny, not to mention all the gas that is wasted while the pcm is deciding what to do.

If you have one of these trucks with this tranny, look at the circumstances I have described, watch your own truck closely and get back to me with your findings – PLEASE.
