How many miles did you get out of your 10R80 transmission before self destructing? 500 miles, 1k, 2k… driving type? Towing, city, hwy, etc.

[Jstang23]

Yeah I think if you bought the mustang thinking it would be as smooth as a cadillac then I think you were mistaken. Also always let the transmission come up to operating temperature before you can expect things to work right. I don't put it in sport mode until at least 150 degrees.

I suspect that most daily driving occurs when the transmission is cold and the fluid is more contracted thus creating a possible low fluid level. Pair that with the A10s seventy shifts per minute, as it constantly seeks 10th gear then has to snap downshift when you need power just to seek 10th again ASAP, and suddenly you've got dozens and dozens of shifts on cold/low fluid.
The recommended operating temp is not even really achievable with normal daily driving as it takes 30+ minutes to get there and, depending on ambients, it may never even get close.

I am wondering if someone with lots of short drives, where the trans temp gauge never moves from 0, effectively needs more than the recommended fluid level.

I have never experienced any rough shifts when I am daily driving. I keep it in drive and drive smooth, slow, and safe. If I am heading to the mountain roads to drive spiritedly I always have enough time to reach 150 degrees.

Its possible if someone only drives short distances to need more fluid but once they get to operating temperature you would see a rise in fluid pressure which would cause more problems than it would fix.

That’s right, there’s a reason the fluid check and fill procedure is done with the trans fluid at operating temperature. Mine was a quart low from factory, the trans tech at my dealer had to drive the car for about 20-25 minutes to get it hot enough to check and fill properly. It was done in January so took a while to get the fluid up to temp.

Here is a rewrite I did to try and make it more presentable. I am open to constructive criticism by proof readers. I have never claimed to be a good or even mediocre writer.

How many miles before your 10R80/10L80 self destructed?


Who rebuilt it?


What parts?


Did you mod your engine?


What type of driving?





Thorough description and details of my 202x has 9,000 miles and is stock! 10R80 Mach 1 transmission problems :


The car and transmission started having problems around 2k miles or so.


My car is at the dealership now for the fourth time and I’ve also had it at an independent shop, they said I should take it to a dealer because it is still under warranty and they have to fix it.


The dealer it is at now is the only one that would replace any parts of the transmission. They tried replacing the valve body, but they’re saying that there is internal transmission damage. They’re saying it’s due to excessive driving.


The car is all stock except for a few chassis/suspension parts.





In my opinion this is false advertising and or a lie. Since the car comes with: Michelin Cup 2 track tires on it from Ford!, Recaro racing seats, track and drag driving modes, 2 front splitters, rear spoiler with Gurney flap, heat exchanger for all the fluids, etc. and Ford marketed it as as a track car.





Ford has steadily built the Mustang into an all-around performer, as capable on a road course as it is on a drag strip, and the company’s marketing and PR efforts steadily push the car’s track capabilities.


So, what happens if you follow that message and take a Mustang to the track? As it turns out, Ford walks the walk.


“Taking your Mustang onto a track does not void the warranty,” confirms Matt Leaver of Ford Performance communications.


from: https://www.hagerty.com/media/news/will-your-new-car-warranty-cover-track-driving/#:~:text=Ford%20Mustang&text=“Taking%20your%20Mustang%20onto%20a,will%20not%20cover%20that%20damage.?vurlk=1732737750008-R87BJ43HA19Y





I get the impression the dealer is going to try to void my and others warranty.


I’ve been doing a lot of research on this transmission and I am seeing that there is a class action lawsuit about this transmission, but I am not clear on what is going on with it. My opinion is did possibly Ford and Chevy buy off the judge? The judge dismissed a lot of the claims but there’s still at least three that are ongoing.





It seems very odd to me that Ford and Chevy together making this transmission would think it’s a good idea to have steel gears running on aluminum along with one of the gears having bearings on one side, but not the other(the P# gear, Or planetary 3 gear). It has other problems also that Ford has TSB‘s and upgraded parts on along with the aftermarket coming up with some upgrades/fixes.





One could ask- How much difference does the black anodized trashcan/clutch container/outer shell make in longevity vs non anodized and steel gears. I am thinking not enough to really mater in longevity? Does it take the life span of the transmission from 2k miles to 2.5k miles or to 200k or 300k?


I i’ve done a little research on this to try and figure out how much of an improvement it is.


I do have not found any answer yet.





List of the latest 6 failures known for now:





If you learn better by visual and audio I have provided below links to such videos.

When it comes to Ford 10R80 failure points, Dunsford a Instructor at SIU, and a couple others I found, describes weak points for your Ford 10R80 and GM 10L80 10-speed to behave erratically and eventually fail.

1. CDF Drum. In earlier versions of the 10R80, a poorly designed bushing inside the CDF Drum slides out of position, allowing a Teflon seal to fail, resulting in pressure loss.
2. Outer Shell Problems. The 10R80’s outer shells are made of aluminum, which is softer than the steel used to make the transmission’s various clutches. Sometimes these clutches stick into the divots in the outer shell, causing weird shifts.
3. Valve Body. Valve bodies are what control the physical shifting in an automatic transmission. But if too much fine metallic contamination collects in the valve body, they behave out of spec. Which is why Dunsford always recommends replacing valve bodies anytime a 10R transmission is rebuilt.
4. (In the 10R80, planetary gear sets and the one-way clutch are vital for maintaining smooth gear shifts and appropriate gear ratios. Deficiencies in these components can lead to improper shifting or transmission failures. A faulty one-way clutch might cause skipping of gears or failure to hold power in specific gears.

Friction clutches also play a role in this system, and their wear can exacerbate these issues. Keeping an eye on gear shifting behavior can alert you to early signs of these problems. Repairing or replacing these components early can prevent costly overhauls. From: https://cartipsdaily.com/10r80-transmission-problems )

Another gentleman and his background:

https://www.f150forum.com/f118/unique-10r80-problem-solutions-experiences-options-566008/

Alright so just for some background, I worked as a tech at Ford for 3 years (during gen1 coyote years). Later became a pipe welder, traveled around for 8 years. Now I’m a welding instructor and have been teaching for the past 2 years. I have plenty of experience with mechanical work automotive and motorcycle wise, with fords work and issues, and have plenty of equipment/ tools to do anything. Currently have several track only vehicles 2 c6 vettas and a TT Gen1 coyote F150. I do a lot of engine builds, mainly LS and its variants, and all gen coyotes, various transmissions, and I also do custom tuning using HP Tuners. The current issue is with my daily F150. Itshould be noted that I am a very spirited driver and rpm shifter lol. What’s not talked about, not replaced even on mild build 10R80’s like Suncoast or Monster, and unbelievably not a TSB, is a very poorly engineered P3 planetary and sun gear. P1 and P2 both have thrust bearing separating the sun gear and planetary. P3 has NOTHING, literally metal on metal, only relying on fluid quality and pressure. So if we have valve body issues and pressure issues like sticking valves in a valve body it’s going to grind down.
Only one company at this time makes a solution and that’s WIT, here’s the link for that:
Cheap for what it is, also has a core charge.

5. Torque Converter Shudder. A problem that was much more common in Ford’s earlier six-speed (6R80) transmissions. Dunsford says it’s much less common in the 10R80 but can be an occasional issue.
6. Gear Driven Pump Noise. Sometimes the pump in charge of moving the automatic transmission’s hydraulic fluid makes noise. Again, this is a less common issue.

Possible fixes or choices I have spitballed:
A) The TransmissionTR-9070 in the GT500? What would have to be done to transplant it into the MACH 1 and other vehicles?

B) Would this fit, work and be a great fix: The 10R140 is the largest 10R family member and was originally rated to 1,050 ft.-lbs. of peak torque in the 2020+ Super Duty. This has presumably been revised for 2023, as Ford debuted the 6.7L High Output PowerStroke, which makes 1,200 ft.-lbs. of peak torque. The 10R140 is currently exclusive to Ford Super Duty trucks.

I really do love this car!
The way it sounds inside and out, the tweeks I have made to the: interior sound, handling, looks, etc.
I put: full Window tenting, full Weathertech trunk and interior, a really expensive nice stereo in it, full paint protective film and some places two layers of PPF, ceramic coating.
I only use high-quality full synthetic motor oil in it. I started using mobile one supercar 5W 50.
I’ve spent a lot of money to protect it and upgrade it!

Spending another $5.5k to $11,000 just for the transmission alone at 9k miles, does not make me, and I am sure most other people doing the same happy!

And on top of it again, do these upgrades/updates truly make the transmission last for 200,000+ miles or is it just make it last 1000 miles more?

Writing has always been my Bain and I have not figured out how to change some of the format properly like spacing and alignment.

If you are a good proofreader and writer and can make this easier to read we are open to your expertise.
Thank you.

There's already a thread... literally titled the Ultimate M6G 10R80 Facts...

I understand you think you're trying to be helpful, but when you title a thread like you did its just noise... No one is learning anything from you trying to insinuate that all 10spds have a predestined expiration date where they self destruct.

Ok educate me/us please.

For starters, keep it short and sweet. Linking to a post on another thread is fine. Pasting all the text from that post was unnecessary and confusing. I literally thought his words were yours, then I didn't know where his ended and yours began again.

No offense, but I do have an attention span, however, I'm not going to allot that much of it to one thread. Documenting things to benefit others is great, but I'm not quite sure what it is you want others to know.

 

[MD18EcoStang]

And, just for the record, I do sympathize with you. It sucks to have a problem like this. A Ford dealer screwed me over on what should have been a transmission replacement under warranty on my 2013 Fusion Hybrid. I guess I didn't get as upset, since it was on the tail end of the warranty. Best of luck to you, whichever way you end up going.
