Question Transmission Learning Algorithm

Would anyone with the knowledge mind explaining the "learning function" of the transmission? With a new truck or a new driver, the computer that controls the transmission should be reset to allow the computer to "learn" the new driver's driving style. That's about as much as I know. What exactly is the computer learning? Once it has "learned" your driving style what exactly does it do? Any help much appreciated.

It's more than just the transmission, it's also the engine control system. I've looked thru the Ford shop manual in description and operation and it only gives a rudimentary explanation focusing only on system diagnostics, sensor values etc....

You would have to get a Ford engineer to discuss anything more detailed which is probably a well kept secret. Just know the system learns the drivers style of operation and adjusts for optimal performance using a variety of input/outputs.

I'm sure that the "learning" isn't a once-and-done process. It may adapt to an owner's driving style and change the initial programing parameters from new, but I'm sure that the adaptation is an ongoing process, where whatever data is captured minute to minute is input and stored to some finite data base. As time and miles progress, the latest data will overwrite the earlier data, so essentially, the learning is an on-going process for the life of the truck. In theory, the transmission program parameters would change--gradually over time--for terrain, seasonal conditions, driving style, road conditions, etc. If you think about how much data would have to be stored from such inputs as throttle position, gear position, torque, acceleration, load, engine coolant/oil/trans temps....you'd need the Cray Supercomputer to store and analyze even a few week's worth of data.

Yes but do you change your driving habits like a new driver would when they get behind the wheel? Not likely.

Or..... disconnect the battery negative cable for 15 minutes to clear the KAM. Does the same thing with less effort.

I've never understood the need for a vehicle to learn my driving style and would prefer that it never did.

Agree, but I was really responding to the OP's question as to whether the trans parameters should be "reset" for a new owner/driver. It could be done, but my point is that the same thing will occur over time, with new data over-writing the older data.

Again, I'm not a Ford guru with respect to the E-modules, but merely guessing based on what makes sense from a data input/storage POV.

Yes it will adapt eventually. Why wait is my point, disconnect the battery for 15 minutes and it goes into learning mode immediately.

Thanks, I will keep those things in my mind. I am new here and I came here to learn. I found this website mistakenly. I was actually searching for this https://edubirdie.org/edubirdie-revi...-and-reliable/ website online because I am searching for the most honest and reliable review online for Edubirdie service and when I was searching for it online, I also found link to your post as well.
