Finally got my Ranger back from warrantied transmission repair. Is this what has been the common issue?

[TannerVoss1231]

Took them 37 days to do this rebuild.
These are the notes provided. Wondering if this is the common issue that causes transmission failure in the 10r80 or if it was just a fluke issue with the snapring not installed right or coming loose. From looking around it sounds like 10R80s have weak snap ring grooves or inconsistent tolerances, which can allow the ring to pop loose. Do they do anything to remedy this in the repair or do they just use the same OEM parts that were originally in there?
I have also heard they are often underfilled from the factory, so I will be checking that quite a bit this week.
Also, someone had mentioned a product called RVS Technology Triboceramic Engine Protection & Restoration. I, stupidly, ordered it based on engine size so it's only for engines up to 4 quarts of oil. Wondering if there is any use for this anywhere on the vehicle since the engine takes 6qts and the trans is 12qts

Thanks!

JL3Z7H351B is the part number for the updated CDF drum. I don’t see it listed on the repair order. Whether it was part of the failure or not why wouldn’t they have put the updated CDF drum in? If that’s the case it’s very concerning. Had this been worked on previously and had the updated CDF drum installed?

No it hasn't had any other work done. Do I need to call them tomorrow and take it back in?

I would at least call them and ask them why

I reached out via text, they never answer the phones anymore after being given the ability to communicate over text.
I've still got 2500 miles on this warranty and I am going to make sure that trans is solid before that warranty is up

This was the response I got:
"Ok so its in your story on what failed. It is the front support snap ring that failed."

From my understanding the snap ring does not fit into the hub correctly which required a new model of drum to be made?

 

[TannerVoss1231]

I am hoping that the TSB says to use the upgraded hub? I wouldn't be excited about another month of no ranger, but I want this done correctly

This was the response I sent her:

"
Yes, that is related to the drum which is supposed to be updated to the new version to avoid the snap-ring issue.

"The primary difference between JL3Z-7H351-A and JL3Z-7H351-B lies in the fact that JL3Z-7H351-B is an updated version of the hub assembly, designed to replace the earlier JL3Z-7H351-A part. This update was implemented by Ford to address specific issues identified in the 10R80 10-speed automatic transmission.
? Key Differences

Supersession: The JL3Z-7H351-B hub assembly supersedes both JL3Z-7H351-A and HL3Z-7H351-A, indicating that it incorporates improvements over the previous versions.

Design Improvements: While Ford has not publicly detailed the specific changes, the updated part is believed to address issues such as dislodged snap rings and clutch failures that were reported with the earlier version.

Practical Implications

Warranty Repairs: If your vehicle is under warranty and experiences transmission issues related to the hub assembly, the dealership will likely install the updated JL3Z-7H351-B part."


Can you look into this, I would rather have the corrected part installed to prevent the issue from recurring

TSB is specifically about the updated CDF drum. I can’t believe a Ford tech would be inside a 10R80 that far and not put the updated CDF drum in. Unconscionable ?‍.
attached copy of the TSB ( note: has been updated to 25-2134 since this one but basically the same)

My god. It's on the first page.
I've got it printed out and I've emailed the GM.
I'll be going in tomorrow to get the correct process started.
I cannot believe this

 

[Stevedbvik1]

They also replaced the C,D and F clutch friction discs which go in the drum.
The issue with the drum is the bushing inside of it. It can move and cause all kinds of problems ( possibly yours). The updated drum has a step machined into it to prevent the bushing from moving.

It’s really hard to believe if that’s what they did. Maybe there’s a screw up in the parts listing and they actually replaced it but not noted.

I have a feeling that's the story I am going to get tomorrow. Seems impossible with how stringent they have to be with corporate to make sure they get paid for their warranty work

 

[TannerVoss1231]

Just met with my service tech and the service manager, this is what they told me:
They can't just replace parts that haven't failed or Ford will not pay them for the parts, so they can't replace the CDF drum because it wasn't where the snap ring failure occurred.
The failed snap ring was in the "front support" which I am assuming is the part number JR3Z-7A130-C.
He said the Rangers don't typically have the CDF snap ring issue, they usually have the issue my truck had. He said the F-150s typically have the CDF snap ring failure
Where I am getting confused is the tech notes say "front support snap ring dislogded". When reviewing this with the service advisor he kept saying "it's not really a snap ring" and then would refer to it as a "bushing" or "sleeve".
What I don't get is that they had to replace the clutch plate assemblies within the CDF, so why wouldn't that warrant upgrading it to the proper part?
I don't know if I should push this further by reaching out to corporate.
What are your thoughts?

Edit: they also repeatedly said the trans tech thought that my transmission already had the upgraded CDF drum. Looks like that part came out in 2022, so not possible on a 2020 that's never had trans work done before.
It just feels like there is some fishy business going on

There's mention of a snap ring in this article. Didn't have time to look and see on your parts list if that's what it was.
