Transmission failed

[Mikestang24]

I live in Houston and Planet does have a good reputation. I work in service at a Ford dealer in Manvel, and in almost six years there, I have not had a Mustang with a 10 speed issue. F-150, 250, 350 all day long though, and there are probably a dozen trucks in the shop now for trans issues.
I suspect, but cannot confirm, that the Mustang units have gears with a straighter cut for additional strength, which would also account for the whine that so many comment on.
Just my .02 that Mustang trans issues are not common.

Might be related to the fact you dealership doesn't sell a boatload of gt's. When searching for new cars, i always check the smaller towns for better pricing

You could be right. I will say that a surprising number of our service customer bought elsewhere, regardless of vehicle type. As busy as we are, larger dealers closer to town are backed up even further.
I love my car, but understand that its just a matter of time til something goes wrong with it...
The onlything I don't like is the damn Sync. They keep promiseing updates, but I have yet to see any that work.

I just don't get it! Someone has a baby failure, or tells a story about his brother's sister-in-law's uncle's 10R80 failure, and suddenly the 10R80 becomes the brunt of misinformation!

The 10R80's failure rate isn't any worse than anyone else's modern (traditional) transmission. The same goes for the various 4, 5 and 6 speed (even 7 speed) manuals. What we don't know is how the transmission was treated? Abuse any part, and sooner of later it'll fail.

If you want to talk about failures, all anyone has to do is look at Nissan's non-traditional CVT! They've used slight variations of their CVT since the late 90s, and still haven't found the magic elixir to longevity. Driving any CVT-equipped Nissan model over 50K miles, and you're on borrowed time!

You should drive mine. It shudders with every other gear change and it's been to the dealership 3 times. Love the car, just wish it would shift correctly.

That’s interesting, may I inquire, what issues are the F series 10R80’s seeing (he asks with some trepidation)?

Baby failure? My 2022 A10 failed catastrophically on the freeway at 70mph. All the fluid left the chat completely and burnt off on the exhaust for a couple miles down the road. Ford bought that car back, at full price. I guess they realized the situation could have been much worse. That was October 2024, and I bought the 2024 in September 2024. At 9600 miles the transmission was already jerking and slipping as well as clunking into gear. Ford immediately replaced the transmission within 2 weeks. I drive somewhat spirited, but nothing crazy.

Main one is CDF drum failure, causes erratic shifting and delayed engagement and harsh engagement in drive and reverse. Some with torque converter shudder and auto stop/start pump failure.
Sadly, its a matter of when rather than if. Extended warranties will cover all this, and an increasing number of them are authorizing a replacement unit vs and overhaul.

The 10R80 is an awesome transmission when it works right. CDF drum is almost always the culprit. The tech at Planet Ford is going to disassemble the bad unit from my 24, and let me know exactly what it was. I suspect i got a leftover transmission from 2023 that was not updated for the CDF DRUM bushing issue.

@SSuperDave, not trying to derail the thread, but hoping you can provide some advice.

I have a 2021 F-250 with the 10 speed (7.3L). I've had it in the shop once because of the very delayed engagement into drive in the mornings. That was about a year ago, and it is getting where it takes even longer now, sometime clunks twice, and is often very harsh. I've not taken it back to the dealer since the first time because they said it is normal and provided me the attached document. They made it sound like they will not do anything for my symptoms. It drives ok once it is in gear and is super smooth once the transmission gets up to temperature. I've had the truck just over 4 years and it is at 40,500 miles. I don't have a Ford extended warranty, but the dealer where I purchased (not my local dealer) provided a "lifetime powertrain warranty", which I have heard are mostly worthless.

Would you recommend pushing the issue with my local dealer? I haul my camper and race trailer with the truck, and I don't want to get stuck on the side of the road with a dead transmission.

Take it to Ford. Power Powertrain warranty is 60k miles. Transmission should be covered

I guess my question is how do you force them to do anything when they provide you with an SSM stating that your exact issue is a normal characteristic of the transmission? Short of waiting for the transmission to fail, I'm not sure what else I can do.

Just have to be very firm with them, tell them it's not normal. Escalate it at dealer level if needed then go to Ford Customer care. Might need to throw in a bad review on Google

 

[SSuperDave]

I asked my trans tech about this SSM, he has seen it and says it is normal, and the even the 10R80 in the F-150 will do it if it sits long enough. What you want to watch for are any changes in the way it works, if it does the same thing all the time and all of a sudden gets worse or different, then I'd say there is a problem. If not, Ford will stand by the SSM and not do any repairs.

Thank you both for the feedback. I guess I'll take it back in since it has definitely gotten worse. It has become much more violent of a jerk when it drops in gear, and recently it has sometimes had to "clunk" into gear twice before it actually engages into drive.

Hey Mega, keep in mind there are thousands of F150's having the same issues with their A10's as well. There's even a few class action lawsuits on these transmissions. I'd like to think it's a fluke, but since this is number 2 in 2 years, and 2 cars (both brand new) for me, I think the issue was never resolved.

I don’t quite understand the 10 Speed Transmission problems?
I have a 2020 F-150 Limited, Rapid Red, with almost 34,750 miles on it. I purchased new on July 15? 2020.
I haven’t noticed any issues yet.
Maybe I just have to wait for it to happen?
I purchased a 2024 GT Mustang on May 17, 2024 in Atlas Blue.
I traded it in for another 2024 GT Mustang with a different color. Rapid Red & the Brembo Brakes on April 31, 2024.
The Atlas Blue only had a little over 4,000 miles on it.
The one I have now has almost 500 miles on it.
I know it’s early but the 10-Speed on both GT’s & the F-150 seemed to shift properly.
They say the 10-Speeds have a way of learning your Driving Habits?
Just have to wait and see?
Good Luck to all of us!

 

[SSuperDave]

The transmissions do have adaptive shift, which will learn your driving habits. Typically, if a failure occurs, its in the 50-70K mile range. Just drive it and enjoy it and deal with the problem if and when it arises. Factory warrant will cover it for 5 years, 60K miles, if you are one who keeps his cars a long time, a good extended warranty will cover them as well.
