10 Speed Owners... please talk to me...

[The Spider House]

I recommend resetting the transmission learning process, and then drive it very gently and consistently for a few thousand miles (maybe as many as 5K) to allow it to re-learn. I suspect that aggressive and inconsistent driving during the initial learning process (aka beating or tracking the car) causes the baseline behavior model to be incorrect. I had a terribly behaving transmission when my 2023 10R80 GT was new, and with gentle, consistent driving and patience, it settled down to the smoothest transmission that I've ever had in a car without any repairs or tuning tweaks, in all modes. Good luck!

Is the resetting only something that can be done with Forscan? If not can you please explain the process to me please for the reset ehere no tuning or intervention required? Thank you in advance.

It is VERY easy to copy the Sport downshift, coastdownshift, and upshift into the base tables using something like PCMTec. You can get rid of skip shifts and stop/start while you're in there. It is odd, though, that you report harsher shifts in sport because the stock calibration uses the same shift firmness for everything except 4x4L.

That's interesting. I had not thought of doing it myself. I already defeated stop/start with the trick of disconnecting the trailer lighting plug under the dash, which forces start/stop to disable all the time.

As for the harsh shifting, I would say that in normal you don't really feel the shifts but in sport it feels like "popping the clutch" with an audible "chung" and small kick in the seat.

My experience with this 10-sp is in my 2020 F150 Platinum with the V8, so functionally very similar. Normal programming is aimed at maximizing gas mileage and completely neuters the performance. It is never in the right gear, never downshifts when it should, is downright "doggy", and is devoid of anything approaching "smoothness" .

I had a rental Expedition for a month and that thing was retarded unless you had it in sport mode.

I finely figured out how my car wants to be driven when in any mode other than normal. Normal mode in my car shifts nicely.

In any sport mode the trick for me was first, reset the BMS, that seems to reset the learned shifting as well. Then don't leave from a traffic light right behind the car in front of you. Wait for about 3 car lengths between it and you which will allow the transmission to shift normally as you speed up. If you are too close to the car ahead of you and you need to lift off the gas the rpm will hang for a bit and then slam into the next gear. That becomes what the tranny "learns". Since I did that mine isn't anywhere near as bad as before I did this.

'19 GT Premium bought new. We got a good one. 30K+ on it now. Had a period when it came out of storage once when it seemed to take a few seconds to go into drive. The issue just... went away. Has always been driven in a "spirited manner".

So I've owned the car since last January, and the praise about how good the 10 speeds are, is one of the factors that drove me to purchase this over other competitors, and i have to say, this transmission is almost as bad if not worse than the 8l90 in my 2017 Camaro ss

*Harsh engagement from P to D(hits my head against the headrest sometimes)
*The kickdown in all drive modes is very delayed when you floor it and downshifts on its own
*Paddles are extremely delayed most of the time (2-3 second delay in response)
*Lots of clunkiness especially between 1-3
*Takes a large amount of throttle input to downshift especially when merging onto a highway
*It hunts a lot for gears at times, every and all shifts are never smooth and snappy

My car is a 2019 10r80, I've seen other 10 speeds in videos and other owners and their transmissions are super snappy, quick, and buttery smooth to where you don't even notice its shifting, almost DCT/10 Speed ZL1 like quickness and smoothness(Having driven the 10 speed ZL1 and CT5V Blackwing at my work, these 10 speeds are light years ahead of mine. What is wrong with my transmission? fluid checked out and isn't low, just slightly brown. Done the adaptive transmission learn table thing and even stopped it all together using forscan.

CDF Drum bushing. I've had 2 go bad on me. 2022 GT Premium 3.55 gears. Transmission did all the things you are describing, after several "repairs " the transmission failed at highway speed. Ford bought that car back. 2024 GT Premium 3.55, transmission started acting up 9500 miles, Ford dealer replaced entire unit. No issues since. There's no recall, but lots of TSB's. I'm assuming you're out of warranty, so I would do the tune that was suggested in this thread.

My 2018 has the 10 speed with 66K miles on it and so far no complaints. I did, however, buy it new and have taken good care of it and hardly ever abuse it. There are some design flaws with the early 10R80 transmissions and if yours was driven hard the part they call the "trash can" inside the transmission (don't know the real name, may be outer shell) can get grooves worn into it and cause shifting problems. Ford has since come out with a replacement part that is hardened to cure the problem. Watch this video.

I’m a technician at Cadillac and work on cars for a living but I’m not on the level as a transmission technician but how hard can it be to replace the CDF drum bushing by myself? I’m also already custom tuned

What is BMS? And should I resume the adaptive learning thing again?

Battery Monitoring System. It keeps track of the health of the battery and may change how some of the electronics work if it thinks the battery is weak.

It's easy to reset, most people do it with Forscan but I use the manual way. Turn the power on in the car but don't start the engine, flash the highbeams 5 times with the turn signal stock, then press the brake pedal 3 times. Then watch the dash, in 10 or 15 seconds the battery icon will flash a few times. When it stops flashing turn the power off and you're done.

Wait, I wanna know who actually praised that 10 speed?
Owners from both GM and Ford have been complaining about it being weak and hunting for gears. I didn't realize there were al that many people out there that enjoyed/recommended it.

I enjoy mine just fine

When it's right, it's great.... when it ain't, well you know

Unless I only used the car for racing and needed the fastest shifting possible, I would never willingly get an automatic. I don't find them fun to drive, but rather tremendously frustrating.

Same for me with manuals. I don't find them fun to drive, rather they are just tremendously exhausting and annoying having to clutch in/clutch out and shift for every single gear change especially in traffic or daily driving. And on track they are slower and take your focus away from driving.

Now a tuned and properly setup 10 speed is pure bliss, especially on track when you're banging 4-5 gears in quick succession up and then 5 quick downshifts on hard braking.
