10R80 harsh downshifts normal or should I have the dealer tinker with it?

[Hans Moleman]

All 22s? Would we get a notification of some sort? My ‘22 job 2 runs like greased lightning ?

sorry I didn’t mean every 2022 have transmission issues. I meant the TSB covers all 2022.

did making your 2023 adapt in sport mode make make the downshifts perfectly smooth or is there still a little bit harshness?

Perfectly smooth, no. But much better than I likely would have experienced in normal. If you do get on it in sport, it does take some time to upshift when you cool down but that’s the whole point really imo. I don’t really have any issues with up/downshifting these days

Upshifts are generally pretty smooth and never have any issues.

Here is when the harsh downshifting usually occurs:
A) 10 to 6 downshift on the freeway to accelerate quickly.
B) 6 to 5 downshift while slowing down with the brakes applied.
C) 3 to 2 downshift while slowing down with the brakes applied.

I have a 2023 PB with 4/23 build date. Not sure if this mine has the revised CDF drum or not because the information seems to go back and forth.

I have reset the adaptive tables already using Forscan.

I have a 5.0 and stumbled onto this thread from the front page, but I have similar issues with my 10R80. The 6 - 5 downshift is what annoys me the most because it's almost always a good jolt, but I also get pretty harsh downshifts any time it skips gears (i.e., 7-5). There exists a TSB (24-2070) where the dealer runs a "PCM - Transmission Accelerated Main Control Break In" routine in FDRS to cycle the affected valve bodies and clear debris which could be causing valves to stick. And I've seen feedback from at least one person that it helped. Though I've personally tried one dealer so far and had no luck in getting them to do anything. Though now that I stumbled on this thread, it leaves me wondering if this issue is just an inherent flaw of the 10R80?

I have a 2023 Powerboost. I am overall pretty happy.... its a bit clunky at times.

But yeah my 6-5 downshift when coasting steadily to a stop is usually pretty harsh. Like it kinda drops into 5th.

I've discovered that if I continually gradually apply more brake pressure it mostly eliminates it.

I've gotten I think 2 or 3 OTA updates on my truck so far. None of which I think had anything to do with PCM and shift logic. All updates except 1 were just like "were making an improvement for future software". I'm also waiting for the Stop Safely Now update....

Thanks for that TSB 24-2070 I will investigate!

EDIT: Little confused now seeing the 23-2250 TSB as well. Maybe I'll just talk to dealer next time I'm there and see where it leads. Please update if anyone has any of these TSBs performed.

I just wanted to give an update. I have 6000 miles now and the downshifts seem to have smoothened up. 10-6 and 6-5 are completely smooth now. 3-2 is occasionally a tiny but harsh but nothing like before.

The other problem there is still an occasional clunk during throttle tip in when on a slight downhill in the freeway. It’s like the torque converter is confused and locking up harshly. It happens mostly in a certain stretch of freeway while tipping in the throttle like 4 seconds after initially releasing it.

There's a TSB on the CDF drum? Shoot, I don't have it and I've been having downshifting issues since I got the vehicle that have been getting worse

I actually also get that thunk on tip in sometimes on the freeway too. Also annoying.

I have identical issues and my truck is currently in the shop. The tech is thinking about replacing the valve body, but idk. Mine is a 2022 so CDF isnt out of the question being as Im only having downshift issues with 1-3-4-5 pretty much. Its incredibly intermittent. City driving, like actual city, is TERRIBLE. I was braking through a right turn at a light and it downshifted so hard it chirped the rear tires.

Was just checking this thread to see if any updates on shifting issues. 6 -> 5 downshift still irritates me. They updated the software once and said it eliminated, but came back. Reset the shift tables once also. It is better but still does it unless I'm applying ever increasing pressure to the brake pedal.

May see if I can get them to do the accelerated break-in routine. My 5 -> 4 can sometimes be as rough as 6 -> 5 but it's more inconsistent. I also get what seems like kinda drops from 3 ->4 and 4 -> 5 usually when the truck is warmed up. I can smooth these out by letting off the throttle a little when I know it is going to upshift.

Also wanted to add I think the CDF updated part was from August 2022 production and onwards.

My truck has the 6-5 clunk when good and hot from city driving also a intermittent thump when taking off from a stop same temperature conditions and Skip down shifts too are hard. Slightly warm cold downshift hard too.

Sounds familiar. If I ever get up to taking it in, I'll follow up if they do anything. I half don't even wanna bother.

Finally took it in. Went for drive with tech. He had computer hooked up to OBD port during the drive etc.

Nothing. Working perfectly.

He said he did reset the adaptive learn as part of his diagnosis. So it must have helped. He said otherwise the computer can basically measure everything in the transmission. Pressures, activation times, if there are stuck valves, surging etc. Says nothing indicating any internal issues with my transmission. That’s good but…

Told me it can learn bad habits or things like towing for a weekend and then not towing can trip it up. Also said there can be times where it tries to shift and immediately lock the torque converter at the same time which feels like 2 shifts kinda occurring at once.

His feeling was the adaptive learning just sometimes doesn’t work that well.

Also filled me in that they generally have a step by step. Software first. Then if showing sticking valves or timing out of spec they do the accelerated break in. Then if still acts up they check the valve body. Then after that it’s the CDF (if the old drum design). Told me that in basically every case the computer will show them when things aren’t working correctly and when you need to escalate the remedies.

My software is fully up to date. He checked my trans fluid level and says it’s good (I also did myself awhile back and it was indeed good)

Helpful guy and I feel really put effort into things. Said if/when my 6-5 downshift and/or 3-4-5 up shift clunks come back, roll by and ask for him and he can usually jump in the truck and hook everything up and evaluate.

I asked him why Ford adaptive learning seems to be finicky vs other automakers and his feeling was other automakers struggle with it too. I do notice an occasional hitch in a Lexus 10 speed I sometimes drive but it is nowhere near the Ford.

Anyway… said I’d give an update so there it is ?
