Transmission re-learning? (Start fresh?)

[FirstFord]

Forgive my ignorance on this subject, and I may not be using the correct verbiage and/or terminology (I know just enough the be dangerous….)

It is my understanding that when brand new, the 10R80 “learns” the driving style/habits of its new owner, and programs itself accordingly. It is from this learning that the transmission develops its shifting characteristics, logic, and strategy. I was pretty gentle with my truck when it was brand new, as I was mindful of “break-in”, but this was also the time period when the transmission was “learning”, so what the transmission “learned” does not necessarily reflect how I typically use the truck. Currently, I am not dissatisfied with the how the transmission behaves, but I think there is a lot of room for improvement. This leads me to a number of questions:

• Can the module that controls shifting be “flashed” (if that is the correct term), allowing the transmission to begin at a new “Day 0” and start relearning all over again?
• If so, can this be done by the owner, or does it have to be done by a dealer?
• If “flashed”, will it remove any OTA updates specific to the transmission?
• Is there a down-side to flashing the transmission module?
• If flashed to start the “relearning” process, and you then “lock-out” gears while driving to try to control the shifting points more, will this influence the transmission’s “learning”?
• I’ve also read on this forum (and others) that driving in “Sport Mode” is the recommended mode to be driving in when the transmission is learning. I assume that Sport Mode teaches the transmission to wind out the gears a little more before shifting?

As I've mentioned, I'm not dissatisfied with things as they currently are, so if "flashing" is not really an option (or a bigger hassle than what I want to take on), then I could very well live with it. But if it can be done, I think I would favor the improvements.

Looking forward to seeing the answers to my questions as well as additional comments.

Yes it can be done by anyone that has a scan tool capable of resetting the transmission adaptive tables. No updates will be removed but you should follow the steps outlined in the service manual.

On the other questions I dont think there is a downside. Also the transmission is always adjusting and adapting it just takes longer unless its reset. On locking out gears I dont know and sport mode at least for a powerboost seems to be the thing to do.

Forscan / forscan lite and a bluetooth obd2 adapter can reset the transmission learning tables.

I'm a little surprised that the transmission memory can be cleared through ForScan (not questing you, mid you - just surprised). I have an OBDII scan tool and have made a few changes using ForScan. Can you be more specific as to which module I need to access the values that need to be used?

 

[RcFlyer330]

Its under service functions / pcm / clear adaptive transmission tables in forscan on windows and similar in forscan lite.

I don't know why you would be surprised that Forscan can clear the tables. Forscan is a very sophisticated tool.

It even allows you to disable "learning", if you so choose.

I'm easily surprised - I'm surprised when I wake up in the morning!

I am far from being any kind of Forscan aficionado - I've made a handful of changes to make the truck more to my liking, and that's about it. I've never done any kind of a deep dive into it, but I've done just enough that I became comfortable with the process and thought that I was getting a handle on the logic that was being employed.

Interesting! So, if one was to clear/erase the "learning" memory, and then turn off learning as you say can be done, what are you left with? I assume there is some kind of baseline shifting strategy that it defaults to?

I suspect that if you clear the "Adaptive Tables" values, and you like the way the transmission behaves immediately thereafter, then disabling Adaptive Learning would simply leave the transmission behaving like it does with empty tables.

Oh, and thanks for being a good sport and not translating my post as any kind of shot at you. I assure you it wasn't. I too barely use Forscan beyond it's simplest features. Reading codes (it's incredibly thorough) and editing Asbuilt values. But it has some really good ICE troubleshooting tools, as well as the ability to flash firmware to computer modules.

Bruce ya got my attention here also... I have been reading for a few years about the shifting complaints and just always considered myself lucky but recently, it has gotten so bad it sometimes scares me. Rolling out of the driveway and accelerating from battery to combustion just jumps the truck like crazy or creeping a right hand turn, etc. Just lastnight I was turning a corner and after a huge lunge\lurch I actually apologized to Becky cuz it gave both us a whiplash affect. I am going to clear these, mabye today and probably not 'learn' again'. Do you have the specific 'do not learn' path also?
Thanks again as always for your input.

JJSnell, in Forscan, the same place the choice the Clear-Adaptive-Tables button is found, there is also a Disable-Adaptive-Learning choice?

I've seen the screen shot around here somewhere, but don't recall which thread.

I'm at the office and away from my personal laptops with Forscan/FDRS. But I'll look it up later.

Thanks man, Ill sniff around today.

Click the wrench icon (service functions page) in Forscan and here is what shows up. The second procedure is stop use of transmission adaptive and the third is halt use of adaptive learning at least on my '22

Outstanding! Mucho thanks!

No offense was taken. I know you better than that. Actually, I don't know you at all, but we have had forum communication exchanges enough times in the past - and you have enough of a forum presence that I kind-of "know" you.....

You, Snakebitten, couldn't possibly be offensive even if you wanted to be, I beleive (my opinion)! I follow a lot of the posts in the shadows, and you're more a teacher than an instigator.

Conversations with a couple of the techs at my dealership in Tacoma have said it really isn't the transmission, it's 'learning' capability, owner or manufacturer - it's training the manual lacks, or more importantly, doesn't emphasize about drive modes. As the owner/operator the techs state to know how you are about to drive and select the mode accordingly, always. Towing in 'eco' mode, pampering the truck in 'sport' mode, 'banging' on the truck in 'normal', these things contaminate the adaptive table parameters. Many of the problems reported by the customer (hard shifts, clunks, mushy behaviors, erratic shifting) have been 'corrected' by clearing the tables and teaching the customer 'choose the drive mode based on how you're about to drive it" (think ahead), and drive it sccordingly. I chose to see how the vehicle acted in sport mode and chose to 'push it' a bit. Scared the holy snapple out of me! As an older guy I questioned 'why would anybody that much rush driving the truck in sport', only to realize perhaps I'm just getting old . I tow, haul, and carry some big and heavy stuff, mostly in trailers - so a 'sport truck' is a whole new concept to me except when talking to my son about the anticts his Raptor group pulls. Yikes! I understand the F150 enthusiast is just about as varied as the population is, therefore the ability to 'train your truck' is just as important to the customer as modifying its looks or 'tuning' for power output. I love driving my F150 XL as much as I do my Solterra, both for different reasons.

Thanks RC and Snake... got em cleared and not learning as of now... will check drivability tonight when we goto dinner...
