ALL The 10 Speed ISSUES I Have Experienced On My Mustang GT....

[@chopdogrulz1337]

At 47k miles my 2018 GT PP1 started having “delayed engagement”. When the transmission was warmed up and you put it in drive or reverse, it wouldn’t engage the gear for about 5 seconds then it would violently slam into gear. This symptom reminded me of older transmissions that were low on fluid. I checked the fluid level and it was fine. So I decided to throw a Hail Mary and service the transmission. After doing so, the problem has gone away completely! I’m at 52k miles now with no issue whatsoever. Ford says the service interval is 150k miles. Complete bullshit! I believe if you service these transmissions every 30-40k miles they’ll be fine, software issues notwithstanding.

[@coastalparasail]

What did the service entail???

[@tonka10r99]

@@coastalparasail I suppose an oil change? Also I would NOT put the Ford Mercon ULV stock transmission fluid back in the transmission. That oil is straight up garbage.

[@Red5oh]

@@chopdogrulz1337 that’s good to hear that the transmission service fixed the problem for you since you’re also out of warranty now. Servicing the transmission can be such a gamble though. I think 10 speed in general is just very quirky. There’s days where it’s very smooth for me then other days it does occasional harsh shift

[@cormaro13]

That’s why I got my 2024 , its stupid smooth and no jerks

[@Red5oh]

2024 definitely has improvements and is smoother

[@marcasswellbmd6922]

I just watch DBP drag his 24 and it kept skipping gears and doing stupid shyt like shifting at 7100 RPM... It's not for me at all.. They all feel smooth when they are new.. Wait till you have 50K on it and then tell me how much you like it..

[@cormaro13]

@@marcasswellbmd6922 bet , I plan on changing the fluid in the transmission to amsoil once I get some more mileage on it , let’s hope for no ford problems lol

[@TheTechGuruCan]

Software issues should be a lifetime fix coz it was a design issue, nothing mechanical is broken from use.

[@Red5oh]

You have a great point. I agree it should be covered and it doesn’t even take that long update it

[@cheekymunke]

I had a 2021. I surrendered it as a 🍋 last month. I couldn’t chance having to repair the transmission after my warranty expired. There were several cosmetic issues that I had respired as well. It broke my heart to give her back but I have a 2017 GT California Special now and had her checked for issues. I can feel how smooth the transmission is on my 2017 compared to the 2021. I experienced everything you have and also loss of power and jerking into gear from reverse. I know not all Mustangs are bad but the 10 speed transmission needs to go!

[@Beliefacy]

6r80 much more reliable apparently wow

[@cormaro13]

That’s why I got my 2024 , don’t experience any of those problems

[@Red5oh]

So sorry to hear that to have your 2021 go like that! 6r80 is definitely smoother in 2015-2017 vs the 10 speed. It’s a shame that ford couldn’t figure this transmission out completely. It’s co-developed with GM and theirs seem to be doing fine. Enjoy your 2017 C/S!!

I just bought a used 2021 mustang gt with 10 speed from carmax 2 weeks ago, so far no issues while i was driving the car especially on highways, i went to the ford dealership and they told me that no software problems on the transmission so far and still has factory warranty.

[@cormaro13]

Go to a performance shop to get a tune for the transmission and it’ll change drastically , after warranty

[@Red5oh]

Yeah that’s good news! If it acts up you’d likely need software update like on mine. Not much mechanical failure on these 10 speed but sometimes it needs software updates

[@coastalparasail]

With my experiences with the 10r80 they have a lot of issues. It’s not every single one of them, but I’ve personally had issues with the 10r80 and I’ve also talked with many people about them having issues as well and then I’ve also talked to other people that have had zero issues zero problems . 🤷🏼‍♂️

[@Red5oh]

Yeah with 10 speed it’s mostly software issues. I haven’t heard of mechanical failures thankfully unless boosted and pushing high HP

[@169abr]

The 10r80 adapts to driving patterns, and adjusts god knows how many perimeters constantly based on what it sees you doing. Weird shifts, clunks into gear, jerking 3-4 and 5-6, all of these are symptoms that I’ve fixed by doing a KAM reset. If you don’t have access to one, pull the battery cable for about 30 minutes and it resets the KAM and the habits are forgotten. If the same issue persists immediately after resetting you probably have a hardware problem.

[@Red5oh]

Yeah I have done a KAM reset before and after that it definitely feels more peppy as it "forgets" daily commute driving but eventually the issues came back. Software update is what really fixed the issues

[@fookingsog]

I've got a 2020 Explorer XLT 2.3L EcoBoost that has a 10-Speed Transmission. I've only noticed hard shifting several times while going up a hill a then when letting off the gas at the top of the hill it felt like it jumped about 3 gears! 😬 As I have driven the route multiple times after that, I didn't notice it happening again. Not sure if it had to do with my driving or if the vehicle computer system actually "noticed" the glitch, learned from it and uploaded the data to Ford via my Wi-Fi connection which I have my car logged into. Anyway, the way I see it, the combination/marriage of the transmission mechanics combined with the computer and software is Ford's "Intellectual Property", so they should be absolutely responsible for any after sales "tweakage" that is required to keep the vehicle running at factory baseline defaults as long as no aftermarket tunes & tweaks have been implemented.

[@Red5oh]

Yeah the 10 speed in multiple vehicles have been reported as quirky. Some have harsh shifting others experience a lot of gear hunting. I see your point and it would be great if ford made transmission updates free as they can do OTA update but of course dealerships have to make money so they will charge. Since yours is still under warranty I would get it checked to be on the safe side so you don't have to deal with it after warranty

[@liarliar1408]

2020, i bought used at 15k miles. I put 5k miles per month as my daily. She's at 30k now. On cold start, if the rpm is over 1k, if I put i to reverse, she would jerk hard. I have to wait till rpm is lowered to under 1k to not get the jerk. I have asked the forum Stang guys n they Said it's normal. Also goin up a hill, if I baby it, seems like the transmission will not engage into a lower gear so I can get more power. I mean in steep hills, I'm doing just 20mph slow and it just stays there but if I gave it more gas, she would go. Looks like these stangs do not like to drive slow. Even at the light and when it turns green, I would lightly go easy on the gas and other cars would just passed me on by. If I give it a little more gas, the turbo might engage and I don't want that. I drive normal mode with steering in sport+ mode because I like some resistance to my steering wheel. The first gear seems to like to hit the higher rpm off the get go so when the gear switches to 2nd, that is when I let go of the gas n baby her for inner city driving. Highway is another story. I loved the exceleration and transmission switches flawless. Think I'm due for a trannie fluid n filter change. The owner's manual was missing when I got the car so I dunno when to do tune up n all that but I read at 30k should do the transmission fluid n filter change. I do changed my motor oil n filter at 7k n air filter at 14k so every other oil change. I have extended warranty till 100k miles bumper to bumper. My window cracked so im trying to get the warranty to cover it for window stress. I might not get it as there is a little crack so it's not a manufacturer defect. $100 deductable on the warranty. Last time I bought in for suspension issues that I thought was the casual of my alignment n tire cupping but they found nothing. I was still charged $200 for diagnostic. This is why I'm hesitant to bring my car in even when I'm covered under the warranty.

[@cormaro13]

Try changing out the transmission fluid to the better stuff like amsoil and it’ll be a night and day difference for sure , also tune with a transmission tune will help with the incorrect gearing ratio

[@Red5oh]

I don't think the transmission fluid change is due until 100k miles so I would probably avoid that. I think most people agree at this that the 10 speed transmission in general is quirky. All the issues you described have been experienced by stang owners. Since yours is under warranty I'd ask dealer to look into and most likely a software update will fix that like in my case. You may need to change your dealer as dealer shouldn't be charging diagnostic fees as it should be covered under the warranty

[@cormaro13]

@@Red5oh the fluid you have in there stock is trash compared to amsoil lol , it’s a night and day difference in shifting when you replace the fluid , everytime I change to amsoil it feels like butter shift and you hardly feel it shifting cause the transition is so smooth and lubricant And it’s recommended every 50k mileage , you have a v8 , that fluid going to be dark by 50k mileage lol , my Mazda 2022 cx30 transmission fluid was dark at 40k mileage lol

[@ms3ben]

My son just bought a 22' GT with 11k miles and the auto often does seem a bit jerky and not smooth. Do you just go into Ford service and ask if the transmission needs a software update?? Some say a KAM reset by disconnecting the battery for a bit does the trick. Is that a myth?

[@Red5oh]

Yeah KAM reset can help as I have tried that but if it's a software issue it will come back. I suggest taking it to Ford and asking if there's a software update available. They can take of you for free

[@josephlewis870]

I think the dealership creates more future problems so u can keep going back so they can get paid tbh

Lol dealerships more like stealerships will do anything to get money from you

[@chemaflores5956]

Mine still has that issue where I go park or reverse is jerky, also going from 3rd to 4 gear is hard as well as having some hesitation. I took it to the dealer and they reset it, and it works a little bit better than before but still doing it, I have hear people say that those issues go away once you get the car tuned, that’s going to be my next move i guess, what do you think?

[@Red5oh]

Tuning the car helped a little but don't count on issue completely going away! Ford's software updates are OEM and are better to address that. If it's still under warranty then I would suggest that before you tune it
