2019 Ford Mustang Owners Have Issues With The 10-Speed Automatic

Ford has achieved some mixed results in recent Consumer Reports studies, ranking below average in the consumer organization’s 2021 reliability study as a brand, while 2022 Ford Explorer reliability is also predicted to lag behind the competition. As for the 2022 Ford Mustang, the automaker’s pony car is also projected to have below-average reliability – based on the experiences of owners of 2019-2021 models – and is also CR‘s lowest-rated American sports car. Now, a new Consumer Reports study has found that many 2019 Ford Mustang owners are having issues with FoMoCo’s 10-speed automatic transmission, too.

Consumer Reports considers the following features to be classified as minor transmission issues – gear selector and linkage, transmission computer, transmission sensor or solenoid, clutch adjustment, rough shifting, a slipping transmission, or leaks. A total of 5.7 percent of 2019 Ford Mustang owners who are also CR members indicated that they have had problems with the 10-speed’s rough shifting and gear hunting.

Transmission issues are one of 17 specific trouble spots that Consumer Reports looked at in this recent survey, which also includes data regarding both minor and major engine problems, engine cooling, the drive system, fuel system/emissions, electrical system, climate system, suspension/steering, brakes, exhaust system, paint/trim. body integrity, body hardware, and in-car electronics. The study examined vehicles that are between one and three years old, highlighting the most troublesome models in the order of severity.

Other reported trouble spots for the 2019 Mustang from CR members include such items as the infotainment screen, which can go blank at random times, windshield stress cracks, and drive system issues. These problems are part of the reason why Consumer Reports gave the 2019 Mustang a reliability score of one out of five – the lowest score possible.

    Not another Ford with transmission problems?

    “Rough shifting” and “gear hunting” are highly subjective. How many of those complaining have never owned a sports car for example? The Mustang is #1 seller in the sporty car segment, all kinds of folks are “Finally getting” that V8 fast car before they’re all electric…

    A V8 Mustang blasting through a low 12 sec 1/4 mile probably won’t shift as “Smoothly” as your garden variety Camry or CRV… Typical of CR’s BS. Without proper context you can make statistics say pretty much anything.

      Nope these arr hard core ford buffs
      Neighbor has 2010 mustang some days only 8 gears some days 9 .
      Been to dealer 3 times no luck

      1. Chris

        Well he will never have any luck with that because the 2010 Mustang transmission only has 5 gears. 🤦‍♂️🤦‍♂️🤦‍♂️ Some people just make $hit up just to hear themselves talk.


    Very hard to keep reading this stuff about Ford. I have been a Ford man since childhood and working at a ford dealer since 1985.

    I’d have a problem if I had a sports car with an automatic transmission too. Maybe car-ma is telling you to get a manual because sports cars were meant to be DRIVEN.

    1. Ford500guy

      I agree whole heartedly.. A Mustang doesn’t need a STUPID gm junk tranny any way.. 5 speeds is more than enough any day.. Give me a 6 speed row your own gears any day..

    “A total of 5.7 percent of 2019 Ford Mustang owners who are also CR members…..”

    i.e. 5.7% = 8 cars 🤣

    Do NOT put stock in CR’s flawed methodology. Their sample size is far too small to be accurate; especially as it pertains to the domestics. Never mind a domestic in a niche segment.

    1. Donald Cleveland

      Also l retired GM was sent to Toyota eng plant all components bubble wrapped come down chute to be picked up and assembled but when l visited Tonawanda eng plant the engine parts come down chute banging into each other with no protection then picked up anf assembled .
      When l showed GM the diff in assembly they were unconcerned .
      Im on my second Tacoma 406,000 on my 1999 271,000 still going on my 2006 ,l sold my chevy with trans problems at 99 k and am waiting for new Ford truck. I have tried them all and Tacaoma by far the best .tires ,brakes, mufflers nothing else period.

    2. Bob

      Where do you get 8 cars??

  6. Materialman

    I guess I got a good one. I bought a new GT Convertible in 1986. I had to put a water pump in it a few years back and a new radiator last year. That’s it! Starts and runs like the day I drove it off the showroom floor!

  7. Chipster

    The title of your article is very misleading. To keep it honest and accurate it should say “5.7% of Consumer Reports members who own a 2019 Mustang have complaints about the Mustang 10-speed transmission.” In other words this CR report and your story are close to meaningless.

  8. Roger Blose

    I have the A10 in my 2018 GT and it is a high performance tranny. With various drive modes, it can be buttery smooth or in sport+ / drag race mode, it is hard shifting just like a manual would be. I had it reflashed at the dealer for some harsh shifting and it works great now. I did not want the Chinese made manual tranny and this 10 speed is actually faster in all testing. And it appears to be very robust based on field and YOUTUBE testing.

  9. Mark L Bedel

    Isn’t this the same transmission that Ford and GM worked on together? I wonder how it’s fairing in the Camaro?

    1. Donald Cleveland

      Yes camaro has trouble with it also

  10. mick1

    Back to sleep, again. Does anybody really believe this nonsense?

  11. Ryan

    Yeah this is pretty shaky, combined too with the fact that there are no issues with that transmission in other applications.

    1. Bob

      False. there are tons of issues showing-up with Ford’s 10 speed including in the F-150.

      The 10 speed was co-developed by GM and Ford, but there are significant differences in both including in the casting itself. That partnership did not end well.

  12. Donald Cleveland

    First 3 cars ford last two tacomas 406 k first one 271k and still going and waiting for new Ford truck manual trans. sold three fords with 135k or less .
    Ever change a v6 mustang water pump good luck

  13. Gary B kempf

    Love reading those people that talk so good about their great vehicles made by other manufacturer. Okay you don’t like Ford or GM but we don’t care! Been driving ford pickups since 1976 and currently have a 2004 f150.

  14. Colin McFadyen

    When in Drive, the transmission tries to deliver the most fuel efficient and smooth experience. Some gears are skipped. In Sport mode, you get all the gears and have full control. The 5L 10 speed is a handful and is not a Camry, Cadillac or Civic.
