Feels like a tuning thing.

That was self evident years ago.

I cleared the tables and halted the learning. It’s been driving more “normal” for the past few hundred miles. Still not great, it‘s more like my f150 now, clunky, but works.

Have just made the changes, reset the transmission settings and halted Adaptive Learning, wont have a chance to drive the car for a while, will post up the results in a week or so.

Did the disabling help your 3/2/1 issues? Other than that this is a very fun car to drive.

No unfortunately not.

No unfortunately not.

other than the 3/2/1 I live the drivetrain in my car. Unfortunately I have zero confidence in any of my local Ford Service Departments. I was gonna pay a transmission shop $100 to check my fluid but if I need the TCM update they cannot help. I was hoping more miles would help but it’s still there. All other upshifts and downshifts are good and 90% of the time 3/2/1 is smooth regardless of temperature so I doubt its the fluid level. So frustrating

 

[MLO 351]

Yes, I topped up the transmission with 1 quart of oil time ago with no noticeable change, to the 3,2, 1 downshifts.
Only options now are an aftermarket tune or as a long shot hold out a while longer and see if the S650 factory transmission tunning has improved and hope that Ford release a software update with similar tunning for S550 owners.

At the very least if S650 10R80 tuning is improved the aftermarket tuners may be able to copy some of the tuning parameters to the S550 in the coming months.

This video from 18.20 onwards provides some hope for better 10R80 tuning options in the future.

Just an a quick update a few hundred miles later… absolutely no changes.
No more adaptive learning bs. Sports mode is a beast and is how a sports mode should be. Before my sports mode was super harsh on every single upshift pretty much no matter what and would be desperate to upshift early. Now it’s way smoother with less “aggressive” driving and a complete monster and very rev happy when you give it gas.

Normal mode is more responsive, before it was an absolute joke how I could apply throttle and nothing would happen. But I will say normal mode shifts a little harder than it did before overall. There’s way less skip shifting on lower gears and doesn’t feel like it’s gear hunting 24/7 anymore

I’m gonna take my A10 in to try and rule out mechanical issues again, but if there’s nothing mechanically wrong, I’m doing what you did. I’m sick of this thing “learning” to chew itself up and drive like a clunker.

I hate the inconsistency and harshness of the skip shifts. 3-5 is still too harsh, and I can pretty much feel whenever my car shifts into 8th as well. I’ve seen people say a tune and disabling skip shift made their car much smoother and I believe it. When it goes from 3-4-5 it’s way smoother than 3-5 skip shift

Wengerd turned that off on mine and it shifts through the gears smooth as glass. Love it now without the skip shift.

will this work with the 6 speed autos as well?

Yes

I've got a 6R80 and I turned off adaptives. I have logged before and after I see nothing in the logs that show anything detrimental. The upside is it shifts the same way everytime. Line and shift pressures have not changed.

So I just discovered this thread the other day I have a 22 GT 10r80, so far so good I am tuned by Lund and I sent a log in after halting adaptive learning and I can say that it absolutely cleaned up most wonky shifting I had after re learns. Lund confirmed that in the log the trans was still shifting at all their commanded shift points and pressures set in the tune. I’ve put about 400 miles on it I’m gonna log again in 500 or so more miles and send it in see if everything is still good. But so far no issues

So there’s has only been one documented (posted) instance of a 10R80 failing after the Forscan changes - but that is entirely coincidental and didn’t have anything to do with the Forscan changes - correct?

For those who have made the changes in Forscan, how long (weeks/months) and how many miles have you logged with the changes?

 

[K4fxd]

I've got about 2K since turning it off, but I'm running a 6R80. No problems

 

[razor19]

I just did this. Runs great now. Any other suggestions?
