I hate my Powerboost

[jesaf00]

Just an update, I took my PowerBoost to the dealer 3 weeks ago and was just informed they ordered parts for a "valve body overhaul". At this point the fact that they are doing anything feels positive.

I actually called 3 dealerships to see about getting the transmission checked and they all said would be 2-3 weeks before it could be looked at and no loaners available. I work from home most of the time but how the heck are regular people supposed to be without their vehicle for weeks without a loaner? Why can't there be a scheduling aspect where they say what day it can be looked at and you bring it in that day?

Anyway, I complained and was eventually able to get a loaner and dropped mine off for the transmission issues, power mirrors, and 20k maintenance (even though I am only at 17.5 but I just don't want to go back in a couple months). They gave me a brand new v8 f-150 sxt and I almost immediately felt the characteristics of the 10r80 which proves that I just hate this transmission. Mine has some extreme issues beyond the normal, it seems, so at least they are doing something.

I will be selling or trading this thing soon. if I could get a lightning without a 20k market adjustment I would do that because we love our Mach-E but I will not buy another ford or gm with this 10 speed.

Man, as a hyper-observant engineer myself, I feel your pain in noticing operational quirks of a powertrain that can drive you nuts. I really do.

But sometimes you gotta just meditate a bit, and realize it is really not that bad. I mean, if you actually think about the incredible engineering of complex physics that enables you to control this 3 ton rocketship on land, performing incredible work off of some basic liquid fuel that you could carry around by hand... I mean, it's absolutely incredible. What a time to be alive, and what a privilege you have to be able to own this incredible feat of engineering.

So your transmission is a little jerky? There's bigger problems to worry about.
We all have the 10R80 also, oh and by the way so do all the Silverado/sierra owners now. It clunks a bit but also delivers an exceptionally wide gearing range with tremendous efficiency and what appears to be excellent reliability overall. I'm new to mine as well, and learning to tolerate its quirks.

Since this thread is 10 pages long now and I'm outta time, did you ever clear the learning out and let the trans start over, perhaps keeping it in sport mode?

I've had 3 10r80's of my own, and 3 more in the family fleet that I have been behind the wheel.
They are not all the same, so I have come to the conclusion that whatever the variances in manufacturing are, it's unlikely a single software strategy can suffice for multiple samples.

Or to put it another way, 3 of the trucks were 2018 F150 3.5 Ecoboosts. So literally identical drivetrains and the same exact version of software. (calibration)
Yet one of them was so nice that it amplified the differences between them.
I then had GearHead Tuning (Matt) tune my personal truck and he's got a great reputation for his shift tuning, and as a result my 10r80 was even better than the one that was previously the best.

My current Powerboost is NOT as refined as either my tuned one was or the best of the 3 oem 2018. But it's not bad. It's actually pretty slick.

Picked up the truck today after almost a month. Drive home still felt familiar and I had 2 weird jerks when pulling into my neighborhood. Too early to tell but here is the info from the work order.

verified customer concern of harsh shifting, no updates available, no dcs. cleared adaptive tables, road test, concern still present, isolated clutches to be the issue and performed trans accel main control break in procedure for solenoids controlling clutches, conn still present. moving forward to Overhaul The Main Control Valve Body.

Glad to hear Ford is making such an effort to help you. Hope It meets your approval after it relearns the adaptive.

Ooooookaaaayyy...
Well I just read this entire 10 page thread over the last hour and two things come to mind...
1. I guess I'm lucky, my '22 PB with 9k miles is actually running pretty smooth. So am I lucky or....?
2. Am I headed towards this issue in my truck and it's inevitable?

Setting all of the house charging this and that aside, I bought the truck cuz it was Blue, 157" and Platinum... I know, I'm shallow.
I didn't need the PB, Blue cruise or other crap, would have been happy with a V8, Blue, 157", Plat.

I feel for OP and based on his last post sounds like he might be qualified for a Lemon Law buyback\replacement?

If Ford is confirming his issue and had it for a month and still can't fix it, then it might be time to sit down with the General Manager and if he plays games, call Ford national and file a complaint.

I hope this doesn't chase you away from Ford's altogether I'm kinda with Snake... Same truck doesn't mean "same truck". I'm in IT and will buy 50 exact same laptops and 46 will be great and 4 will run slow, ideally the same laptop, but they will have different chips, memory, hard drives\SSDs, etc... And maybe that's what OP has... Different chips, different something internal, supposedly same truck.
How many times have you ordered, more tile, shingles, flooring? Same name, different LOT numbers and in turn different product?

Keep us posted brother, we are trying as best possible to support you... Maybe someone with Lemon return experience can offer suggestions?

? agree on the rough shifting. My wife's Durango with the 8 speed auto was worlds smoother.

Took my truck in 6k miles ago to get the tsb done on the transmission and it's been night and day difference. While still not quite as smooth as the Mopar, it isn't far off now. Sooooo much better. Used to be light driving in eco mode was the worst on the 1-3 shift. Haven't noticed a single clunked shift since.

The rough shifting on my 22 PB is in gears 1, 2, & 3, and when it's deciding between battery and engine.

Tonight I was in stop and go traffic. It was not shifting smoothly because of the above. I switched it to Tow/Haul mode, which locks out the electric motor. The engine runs continuously. Shifted smooth as butter after that.

I agree with the OP. I hate his Powerboost, too.

Just to be clear, I want it on the record that I still hate the OP's Powerboost. Not Snakebitten's though. His truck is cool AF.

 

[jesaf00]

OK, truck is back in the shop as of last week. Those 2 jerks I mentioned above manifested into clunks that was happening when accelerating or even decelerating like something was shifting back and forth. I will include a video which was taken the day after I picked it up. Over a couple of weeks it would get louder and on days it did it, it was very consistent. Then, some days it just wouldn't. Maybe rain/humidity?

--Also, sometimes if would do it when pulling into my garage when the front wheels would hit the lip on the floor.

I drove it with the master tech and of course on a rainy day but it did make the clunk lightly by the end of the test drive. So after dropping it off last week I have received one communication that so far they are not hearing it again on a test drive so I sent them the video.

My best guess after looking around is that maybe the drive shaft needs lubricated? I am not sure how it could be related to the valve body overhaul, but IDK.

On the plus side, the main jerkiness, beyond the normal for the 10 speed, seemed to be mostly resolved. Hopefully they can get this clunk fixed.

The video has the clunks but was pretty light compared to what it turned into. The clunk is coming from the rear or mid to rear and you can definitely feel it.

Any thoughts?



Oh, and they gave me a $90k Lariate lightning as a loaner for 6 days! They ruined me and no regular truck will ever be as smooth as that.

 

[Snakebitten]

Yea, it's tough to expect that 10r80 to shift as nicely as the no-shift Lightning.

 

[F150Flyer]

So first time long time here. I have a 21', 53k miles on it, and I have had no issues. The one thing that I can't stand is the high pitched whine that comes and goes when accelerating. No answers from the dealer on that, and have been watching this board somewhat religiously for solutions. With all the other stuff you all have been through, I know I'm lucky. Love this truck.

@jesaf00 Post your VIN and we can see if you have updates (willing to bet you do). I live in Houston and wouldn't mind helping you update if you do and see if the ride gets better.

Way to step up Speed! Class move sir. I feel bad for almost going with the "Try taking it out of sport mode and see if you like it better" wisecrack. I'm thankful I never started typing.

I've trained my right foot muscle memory to smooth out the 1st to third nose dive. It's very similar to my 2022 Subaru Outback XT with the 2.4L turbo boxer and a stout little simulated shifting CVT. It jumps and then nose dives prompting you to overcompensate and blast off until you learn to just hold your foot position steady right at the start. Feels unnatural at first but it works. I'm describing normal mode which I prefer for daily driving chores. I find the electric only to hybrid transition in normal mode to be wonderful when compared to auto start/stop vehicles.

 

[JExpedition07]

The only thing I don’t like about the 10R80 behind my 5.0L is the 1-3 skipshift at low speeds. It sort of jumps/lurches at times, my one buddy says his 2021 XLT with the regular 3.5 Eco exhibits the same problem at low throttle.
