Resetting learned transmission algorithms?


Recommended Posts

Hey guys. I'm interesting in if there is a way to reset the transmission on my 2014 fusion such that it forgets the driving habits it has adapted to. I've noticed it tends to hold onto gears and is usually jerky before it warms up a bit (jerkiness is limited to a cold engine, but it still holds gears). It's almost like it's predicting I have a lead foot and shifts as though I were drag racing or something when I am very much not (not in today's world with gas prices LOL). Does anyone know of a way to reset the transmission computer so it can relearn my driving habits and run more smoothly? I'd be happy if I can do it without using an aftermarket tool or computer.

The Fusion transmission doesn't adapt to your driving habits.  It is designed to adapt to it's own internal tolerances, doesn't matter how you drive.  It's also designed to hold gears when warming up specifically so that it (and the engine) can warm up faster.  This helps emissions and also gets the climate control system warmer air sooner.

 

You can disconnect the battery and some of the settings will reset, or you can use the tools and reset even more things, but more than likely it's just going to learn itself back to the same place again.

I’ll take your word for it, but in my research, a lot of people mentioned the transmission adapts to driving habits. I’ll try disconnecting the battery and see what difference it makes.

A "lot of people" say a lot of things on the Internet about a vast array of topics.  I'm not going to give out personal information, but I'd strongly advise you listen to what Waldo is telling you.

And they’re all wrong,  it’s an urban myth.  drolds1 and I both know the guy whose team wrote the original software.  Waldo is correct.

FWIW, I'm not happy with my 2010 Sport's transmission's reactions either. As the OP observed, there's a low-speed stumble followed by a tendency to upshift too quickly (perhaps for fuel economy) which causes the car to almost bog. By comparison, the six-speed in my wife's 2015 Hyundai is much smoother across the board. For that reason, I'm tempted to get a tune to see if that results in better drivability.

Hi piratepress. First...How many miles on your Fusion and have you flushed/filled your transmission fluid? If yes, how may miles ago and have you checked it lately for color, odor, condition etc. lately? If not, you should start there, in order to rule out a transmission issue causing your shift issues.

 

Although I am not one to recommend "tunes", a tune that also reprograms the transmission shift tables may help, if there is not an underlying problem with the transmission in the first place.

 

As far as comparing a 2010 vehicle to a 2015 vehicle? You would get the same result if you compared your 2010 to a 2015 Fusion or a 2017 Fusion Sport.

 

Let us know what you decide and any results, and good luck.

I think the Sport used a different trans, but when I first got my 2011 Fusion (used), the 6F35 was horrible. When cold, it would sometime race and then slam into 2nd and (I think) 4th or 5th. It would then act weird for awhile until it settled down. A software update mostly fixed it. It would instead go into a 'power hold' and then do a firm shift and not get confused afterwards. And even then, it seemed to happen much less often.
