FORscan adaptive learning reset (2021 Ford F150

[portlandsonics]

Does FORscan have options to reset adaptive tables for 10 speed transmission? Also I heard there may be an option to turn off adaptive learning for 10 speed?

I have a brand new 2021 F150 and the transmission is not smooth and jerky. Not happy with it at all. I have my cable coming in tomorrow so hoping FORscan can fix it.

I'm very curious if other people had luck with FORscan to fix any 10 speed issues with the 2021.

Ive owned my 2021 XLT 5.0L V8 for about a year and have been struggling with the dealership to admit the truck just plain sucks. Finally they admitted (not in writing) the tranny is what it is and is built for a heavy foot driver. Pretty much go kick rocks. I asked if they can turn it off and they said they cant turn off the adaptive learning in my "truck version". I honestly think they didn't know how. I saw some you tubes on different year models. Im buying the OBD connector and going to try it my self. I will reply here after I destroy my truck to tell you how NOT to do it.

You can clear the adaptive shift tables with FORScan. I'm not sure if other engines got PCM updates or not, but the PCM update on the Powerboost made a big difference in how smoothly the truck shifts for me.

Ive seen a video of another person stoping or freezing the learning. Do you know if FORScan can do that for my truck?

Just as a note, resetting adaptive shift probably alone won’t help your issue.

I was one of the people who had a *lot* of issues with the 6F35 transmission early in its life, and I had occasion to talk (via email) a bit with engineering in how the adaptive shift programming works, in trying to sort out longstanding issues with the 6F35 in my Fusion. It works similarly in the 10R80. Basically, it doesn’t adapt you *your* driving style at all. It allows for less calibration of parts at the factory. In essence, the vehicle learns how hard to apply each clutch in the transmission for optimum performance, allowing for manufacturing tolerances to be compensated for automatically by the transmission. When you reset it, the vehicle defaults to its basic program, which applies the clutches fairly aggressively. Over time, it “learns” how much force each clutch needs for what it considers an optimal shift. Ford tends to default on the fairly harsh side, as this provides less slip, and therefore better fuel economy, so generally there isn’t a *huge* difference between the fairly aggressive default program and what it learns. As the clutches wear, it learns to compensate how much force they require, too. There’s no reason to want it off, since it doesn’t learn from your behavior.

My one 6F35 had repeated issues AFTER a rebuild getting the shifts right. On the 6F35, 1-2 is a dog clutch, then 2-6 are all clutch to clutch shifts. 1-2 would perform fine, naturally, but particularly 2-3 and 3-4 kept having slow shifts with RPM flares on the tach as the transmission slipped once the transmission finished the initial adaptive learning sequence, but performed normally in default program before it learned. We would reset the adaptive program and I’d be happy for a few weeks, then it would start slipping again, ad naseum. Resetting the program never solved the issue, it just masked it for a few weeks. What finally solved the issue was a PCM update that corrected an issue that was causing low pressure issues on certain valve body revisions. Most people didn’t notice it, and many vehicles weren’t impacted, but because my vehicle had recently blown all 5 clutch packs, I was attuned to the slipping.

Looking at that SSM, it looks like solving the actual problem requires completing that process to clear the contamination, and that resetting adaptive alone won’t solve it.

Is this a widespread issue? I have experienced ZERO issues with my '22 10 speed (admittedly only 1,500 miles)

Did you find a manual tuning helped the issue?

Never tried, vehicle was still under B2B warranty throughout the whole time we were troubleshooting, and I didn’t want to give them a weasel out point because the dealer and I had already sparred over the vehicle because it was 2 days shy of lemon law on the rebuild alone (Ford corporate was actually great, but this was back when you could actually *talk* to a regional CS person directly, but the dealer service manager was mad because my sale had included a loaner promise and it cost his department a fortune).

In the end, it was a different dealer who figured out the reason the issue persisted after the rebuild. They had it to do a pressure test and he realized the vehicle still had the calibration version for the original valve body, not the new one installed during the rebuild, and needed a PCM update, or something similar to that, it’s been a while. Vehicle drove 50k miles without issue after that before trade in.

Come to find out my Dealership never tried ANY troubleshooting other than check for DTCs. Just topped of fluid and reset the tables then told me they didn't notice any issues. Here are the TSB's related to this issue:
FORD TSB #SSM 50529
FORD TSB #SSM 50329
FORD TSB #SSM 50184
FORD TSB #SSM 49582
FORD TSB #SSM 49507
FORD TSB #SSM 50184

All say no DTCs may be present and contaminated valves could stick causing delayed engagement. I have to find a more competent dealer in m area and update this thread after.

Casco Bay Ford is a joke

Having been through this with a previous vehicle and transmission, changing dealers absolutely can make a huge difference. The transmission tech at the dealer I bought my Fusion from way back when was out of his depth on the 6F35. I’m sure he was great with older, banded transmissions like the AOD, but he was struggling to test and diagnose the clutch-to-clutch 6F35. When I went to a different dealer the difference was night-and-day.

Took the truck to a different dealer and they took apart the tranny according to the 50529 TSM and found a spring on the valve was damaged and they replaced. it. I have not drove it yet but I am hopeful that it is fixed. I will update when I know more.

 

[Zar7926]

Holy Sh*t Its fixed! I couldn't feel a single gear shift from 1 to 10 after they replaced the Control Valve Spring.
