List of 10R80 transmission threads...so far...

[AzScorpion]

From reading here, other Ford forums and several transmission specialist's websites it seems there are a few key components and/or conditions that bring about failure in the 10R80. I regurgitated some of that information here.

There are a few aftermarket shops addressing component issues and some owners are modding their transmissions (the temperature control being one in the Mustang forums) but I'm starting to think we are aggregating information that applies to our 5G trucks specifically - mostly because practically all 10R80's prior to 2023 (according to the TSB in my post link above) have the problematic CDF.

I wonder if that's why my '23 feels so much better than my '19? I noticed this right off the bat when I picked it up it shifts so much smoother/better. No weird clunking or cold start delays and it was cold (upper 30's/low 40's) in a lot of the places we were in June. Now with 6,800 miles on it it's still super smooth both city and highway driving.

I drove my '19 for just over a year un-tuned and it never felt this smooth and always had weird shifts. IIRC that had around 9,000 miles on it when I bought the Livernois tune and 32,000 when I had the accident. In that time it ran much better but still not as good as this one. II was going to transfer my Livernois tune to it but 'm starting to think I may just leave this one stock for a while and see how it is next year. I do miss having the extra hp/tq but one of the main reasons I tuned it was because of the way the transmission acted.

In the 3222-2428 TSB the CDF part number listed as the replacement is here: (wonder if the original one is different #?)

Note JR3Z-7J351-B replaces JR3Z-7H351-A so if you get a replacement /rebuild make sure the old A design doesn't get stuck in there or you'll just do it all again.

Just talked to my local dealership. According to them no one has anything to worry about; they fixed all the 10R80 issues in 17-18.


Autonation Ford in Houston.

It is all in our heads - ignore the TSBs and failures.



Also I sent them an XLT build with simple stuff for a 2024 and they sent me a quote on one with the v6.... yeah no. That would be cool but no.

I think it took mileage before a CDF would fail. I do think something must have changed in the valve body but haven't found any published evidence of that other than TSBs saying to replace and reprogram. That's way cheaper than pulling the transmission and rebuilding it.

At this point after so many failures across Ford/Lincoln vehicles it's likely the newer versions are sorted out. If mine fails and is rebuilt with the new parts I'd have confidence in it. I'd like the Raybestos upgraded GPZ clutch packs since Suncoast puts them in even their entry-level transmission and possibly their specific valve body but that would be completely out of pocket.

Dang. Well, I guess I’m glad I sprung for the ESP.

I just posted in another thread a very similar experience between my 2019 Ranger and a recent acquisition of a 2023 Ranger. Thank you for sharing your experience @AzScorpion & @Racket for linking up the new thread with your research here.

Overall the 2023 transmission has been far smoother and regardless of tire pressure I don’t have the highway bumpy ride. A lot of subtle improvements all around.

Just curious to those who have had transmission failures.

What maintenance schedules have you done? Not trying to pin blame but trying to see if changing filter/ fluids earlier will help. Anyone who had a transmission failure have the PPE pans installed?

 

[djsilver]

I haven't had any issues with my 2023, but there is an active TSB 23-2123. The short story is that the adaptive tuning logic doesn't have enough range to deal with wear over time. The fix is an adaptive learning cycle and/or a valve body overhaul. https://www.tsbsearch.com/Ford/23-2123

 

[Racket]

Interesting change.

As everyone here probably knows, my 19 trans ran just about perfect as anyone could expect...until at around 95k it suddenly began shifting HARD into second gear...I detailed a full fluid/filter change at my build thread but the conditions only got worse...trans eventually blew at just under 100K mile and a new trans was installed around Christmas 2022...the new trans shifts fine just...like the old one did before SHTF...I don't believe the PPE pan is going to prevent a catastrophic failure...MBS stick is your better solution for monitoring correct fluid level...

 

[RedDakooter05]

This is why I kinda ignore anyone that says "Oh this transmission is perfect" when it's only a few years old with 20-50k on it.
Any transmission should be working normally at that point...


I still don't trust the 10R80 completely at this point.

For the sake of compiling information I'm just posting this here:

This article from last summer, F150 with the 10R80. The author found the problem via a diagnostic tool while driving since the truck wasn't throwing codes. Valve body repair was needed. 20,000 miles on it.

Charlie had "monster" tires that could float a F150?!

That part of the story was pretty funny. Diving in the water with a rope to retrieve the truck/boat trailer.
