NHTSA drops investigation of 2011+ Mustang’s 6-speed MT-82 transmission

2011 Ford Mustang Shifter

Back in August the NHTSA opened an investigation into the 2011+ Mustang’s Getrag MT-82 6-speed manual transmission after owners reported cold shifting problems, binding gears, difficulty engaging in shifts and excessive noise and vibration. Last month Ford responded to those concerns, citing the various fixes that were done to rectify the problems, and now the NHTSA has officially closed the investigation claiming that “there is no indication of loss of motive power or unreasonable safety risk associated with the alleged defect in the subject vehicles.” Here is the official report from the NHTSA:

The Office of Defects Investigations (ODI) analyzed complaint data provided by Ford as well as complaints submitted to ODI from consumers. In total, there were 364 unique reports indicating various shift quality issues while driving. Ford identified several factors that may contribute to shift quality concerns in the subject vehicles, including cold transmission, clutch stay-out at high engine speeds, gear clash or grinding, and gradual loosening of clutch plate bolts in some early production vehicles. The largest percentage of complaints indicated higher than expected shift efforts in cold ambient temperatures. These complaints were related to transmission fluid viscosity and the higher shift efforts resolved themselves with the drivetrain warming. Ford published technical service bulletin TSB 11-3-18 to inform technicians that a lower viscosity fluid was available for use to address the cold shift issues. The clutch stay-out condition typically occurs at engine speeds greater than 4000 rpm. It does not prevent the selection of any gear, but may delay clutch re-engagement depending on how long the driver maintains the higher engine speed. Ford identified rotating inertia of the clutch components as the root cause and replacement clutch pedal parts were made available under Ford TSB 10-19-4. A number of reports alleged increasing difficulty selecting gears along with gear clash or grinding. Grinding or notchy gear shifts may be caused by gradual loosening of clutch plate fasteners, which is promoted by certain aggressive shifting. This condition is progressive in nature and initially results in symptoms related to shift quality/feel. Clutch plate bolt loosening will not result in inability to select any gear unless the progressive symptoms are ignored until complete clutch failure occurs. ODI’s analysis identified only five complaints alleging an inability to shift into gear due to loose clutch plate bolts. None of these resulted in a stall and gear shifting could occur before engine start. A revised fastener was designed and implemented in production and is available for service through a special service message. There is no indication of loss of motive power or unreasonable safety risk associated with the alleged defect in the subject vehicles. This preliminary evaluation is closed.

    UNACCEPTABLE

    SAD.

    Seems that NHTSA is not as strong as needed. Did NHTSA drove a mustang with that problem? Or did they check one mustang in a external workshop?.

  • Scuba Steve says:

    Stop whining. If you hate your car so much, get rid of it. Your manipulation of fact caused one of the biggest wastes of time of the year because you were unhappy. Shut up.

  • Henry Ford says:

    Don’t blame Ford because you can’t drive a 6 speed stick.

    And as for JMatero, you are suspect. We all know of your issues with just about every car, motorcycle, and household appliance you’ve ever owned. Personally I think Ford should distribute your picture to all dealers and warn them not to sell to this person. Send him to the Chevy dealer.

  • Keith Stone says:

    Ford has done everything they can. Stop whining and buy a Camaro.

  • Steve says:

    It doesn’t take a scientist or a mechanic to figure out that there is absolutely a loss of motive power if the car refuses to shift into gear on the highway, or at a stop light. Either way, everyone in the world now knows that Ford uses a Chinese made transmission in the Mustang, and that it still has issues. And the Camaro beats the Mustang in sales month after month now, wonder why? And the issues don’t stop with the transmission, just Google “5.0L Mustang Oil Consumption”. All Mustang buyers should be careful until these issues are resolved.

  • 4LS says:

    ^
    Aww, is someone butthurt that they got beat by a 5.0?

  • Awsome MT82 says:

    Jmatero ruined it for everyone… I’d be pissed if I had an actual problem with a Mustang; they will have an uphill battle now.

  • Art J. says:

    Nevertheless, the transmission is flawed, the car’s value has been hurt as have it’s reputation. Add to that, owner dissatisfaction with Ford’s bungling of this issue, and it adds up to lost sales in the future. Short sighted bean counters win again. The problem was never Matero, it was a defensive reaction to criticism by adolescent Mustang owners. KILL THE MESSENGER!

    Actually I did Goggle it. Other than a couple of isolated cases, and a few break-in periods of heavy oil consumption, the 5.0 is typical.

    Why is the Camaro selling better? Who knows, it doesn’t DO anything better than a Mustang, model to model. Other than it’s zaftig styling which is “newer” I can’t think of a reason. (The 05+ Mustang roof is on it’s 9th year. Even though it’s been refreshed it still looks the same to a lot of people).

    To 4LS, Keith Stone, Henry Ford, and Scuba Steve:

    remove yourself from the gene pool, idiot.

  • Michael says:

    I really cant believe the people who are bashing owners for having problematic issues… I own a 5.0 with the mt82, and the owners are right, it really does suck… popping out of gear, and getting locked out of gears (not talking about the (1->4) economy setting, im talking about getting completely locked out of gears)… its a very temperamental transmission, sometimes it will go into gear like butter, sometimes you hit some kind of invisible block that is nearly impossible to get over and finalize the gear change, ford addressed the minor problems, the “cheap fixes” like fluids, springs, etc… its funny i just had mine in service today to address the clutch stayout problem, and they didn’t even fix it or even tell me the final diagnosis, but thats the dealerships fault… but it does figure Ford would avoid the biggest problem… THE DESIGN OF THIS CRAPPY TRANSMISSION.

  • Andy says:

    I have the exact same problem as Michael. I dont even enjoy driving the car because I’m scared of trying to slip it into third and hitting the invisible wall. I wouldnt have bought the car had I known it would be this annoying to drive. I was really excited about having a 6 speed manual. At this point I honestly feel like selling it. I love everything about that car, except the tranny.

  • Caves 51 says:

    I have a 2012 BOSS and have very minimal trans problem if any at all. The thing i don’t like is the trans itself.Made in China .I an now seriously looking at the trans they put in the SS shelby .The Tremec T-56 for my BOSS .The trans is just better and for the money i paid for it this trans (T-56 ) should be standard issue.
    As for the Camaros having better sales ,,,,More women buy Camaros.
    Thanks and good luck.

  • frank beutel says:

    ive got 2012 v6 manual. from day one i was concerned about transmission. i thought that ill learn how to drive this particular car. i looked and read on-line about the issues on trans. i found out that im not the only one with the issues. im not crazy. reverse first and second are hard to get into gear and lots of shudder that seems to get worse! took to dealer and their responds was no fix yet, if more people complain than maybe they will do something about trans. im embarased to tell and to drive with friends or family.spent lots of money for a piece of junk! i dont even want to drive it anymore. and its probably not worth anything. i hope ford comes up with a fix. or ill have to take a loss and buy a foreign car. big mistake ford! lets get it fixed! please!

    Some of you have alot of B.S. to say.

    Mass produced vehicles are going to have a faulty part here and there, or perhaps a part that wasn’t properly installed.

    The MT82 is a solid transmission. I once took my 2012 GT (at wide open throttle) from 3rd to 4th and back to 3rd again on accident, instead of 5th gear. I tached 9,000 rpm and spun a rod bearing in 3rd gear, but the transmission? The transmission felt good as new. No problems. Even after the spun bearing, the engine held together for another month before a rod started knocking.

    Ford makes quality products, people.

    Why has nobody mentioned the Tremec 6060 issues? Or all of the junk from GM that wouldn’t even go into gear (yes, new automatic transmissions) just a few years ago? Is it because the 5.0′s are so superior to the competing Camaros and Challengers (which snap rear suspension parts on hard launches) that idiots have to blow up every little example of the occasional “bad” or “somewhat hard to get into gear when cold” Mustang transmission to feel better?

    Getrag supplies BMW, Ferrari, Audi, Porsche, VW, Jag, and has supplied a few GM and Mopar vehicles as well as the current Mustangs and upcoming Getrag/Ford double clutch trannies.

    BTW, Getrag/Ford designed and developed the MT82 in Slovakia.

  • Pete Martin says:

    I own a 2013 Boss 302 with 700 miles on it and I cannot shift that junk Chinese transmission into 3rd gear over 6000 rpm so the track car I bought is not going to be able to perform on the track. Ford does have problems with that trans and they should stand behind it.

  • terry says:

    so what did ford do about mt82 5th gear problem was there a recall or what
