My manual trans Mustang have shifting problems just like other 2011 and 2012 owners. Sometimes it has huge noise going into 2nd gear and sometimes it simply refuses my shifting. Please have it recalled after investigation, I am so frustrated. Thanks!

Was turning left at approximately 35 mph to get onto hwy on ramp. Had clutch in on manual transmission and stick in "out of gear" position during turn in anticipation of dropping to lower gear to gain acceleration. Was unable to put stick into 5th gear after three attempts - seemed "locked out" of gear. No grinding noises like the clutch wasn't in; just like the gear slot didn't exist. I released the clutch and pushed it back in and was finally able to get the transmission into 5th gear.

I was driving to California to visit my good friend [xxx]. I was at a stop light trying to turn left and I heard a crunch or whine. It's probably from my car or my wife is munching on a oreo or whining again. Try my hardest to put in gear and I was locked out of 2nd and 3rd gear. Someone driving a crappy titan almost rear ended me because of that. This MT82 transmission is total junk, I wish I bought a automatic like 2006fan. I rather let people laugh at me for driving automatic than this. Information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6)

6 spd manual transmission, unable to upshift to 3rd gear around 4000 RPM. Had to wait until the rpms came down below 2000 before it would go into 3rd. Was accelerating from an on ramp and trying to merge with the 65 mph+ traffic. Had to ride the shoulder for a bit until the transmission would let me shift. Not safe at all.

I have a 2012 Mustang with the getrag MT82 6 speed transmission with the know issue of notchy shifting and sometimes not going into gear. More than once while making a turn I found myself going to slow for second gear and when trying to go to first gear I am locked out. So I am forced to either unexpectedly slow down to a near stop to go into first which could lead to a accident, or go to second and hope I don't stall. This is a problem I have never experienced in any other manual car I have driven (2007 Honda civic, and 2009 Ford Mustang).

2012 Mustang GT 5.0 build 2/11. Shifting into 2nd gear has a little grind but feels better or completely goes away as the car warms up, also when turning shifting from 1st to 2nd has a grind no matter if the car is warmed up or not. I have also been locked out of 3rd gear under acceleration. This appears to be a safety concern as I have to deal with an inconsistent transmission.

This vehicle is sometimes difficult to shift into gear. Shifting into reverse is a challenge requiring unusually high effort to engage push-down mechanism. Shifting into 1st from standstill is usually difficult and notchy, sometimes requiring me to do it all over again, even when I am blocking traffic. 1st-2nd shifting is sometimes uncertain as is 2-3, 3-4. downshifting into 3rd and 2nd grinds sometimes. Clutch fully depressed fully at all times during shifts. The transmission also feels and sounds very clunky upon clutch depress/release.

Newly purchased 2012 Mustang coupe V6 has unusual trouble shifting from 1st to 2nd gears on the 6 speed manual transmission.. the shifting is not smooth, and feels notched as you slide it into place. Incident occurs daily, and concerns are rising for premature wear on the transmission. Currently inquiries have been made with the dealership, but no action has been taken.

June, 2012 (2012 not a dropdown option). I currently own a 2012 Mustang rtr, this was purchased this year in June with 300 miles on the odometer. I experienced intermittent engagement problems with the transmission with gears 1-3 either upshifting or downshifting pretty much out of the gate. What happens is the gears fail to completely synchronize with the clutch in, resulting in anything from a partial lock-in, which causes the gears to grind, or a complete failure to engage, which requires a shift to neutral and repeated clutching to get a synchronization to occur. Currently the car has approximately 1500 miles and the problem continues on a completely random basis. I have not taken the car back to the dealer as nothing I do behind the wheel can make this happen at will and it wasn't until I was recently informed about the NHTSA's ongoing complaints with this issue that I thought I should voice my issues as well. While these occurrences have mainly been centered around the 2011 model year and have not yet resulted in an accident, I do not wish my model year car to experience a catastrophic drivetrain failure to be considered for a recall.

I am hereby lodging a complaint about the MT82 transmission im my 2012 V6 Ford Mustang, and you may also include my 2011 V6 Mustang as well, as it also suffered the same problem. The date given is not the 1st, nor will it be the last time this has occurred. 99% of the shifts fine, however...sometimes at low speed the trans will 'grab' the teeth or grind while shifting and shifting at speed(entering a highway or passing slower traffic)will result in gear 'lockout' and over revving....mostly on upshifts, but sometimes on downshifting too. I know I am one of a growing list(and an 18 year Ford dealer employee)of Mustang owners experiencing this problem...Ford needs to get on this before their reputation and the Mustang heritage becomes tarnished!!

Mustang 8-cyl

  • 4,100 miles
I own a 2012 Mustang, purchased 06/13/11.I have had the car for about two months and have experienced many problems with the car. The check engine light care on the second week I bought the car, it stayed on for a day then went away, I figured it way bad gas, but I may have been wrong. The transmission has been very notchy when shifting from first to second gear ever since I purchased the car. Normally this notchyness goes away when the car is warmed up, I try to baby it as much as possible in fear of damaging the transmission. On two occasions, when shifting from first to second I have had the transmission pop out of second gear, this was under slow acceleration. Luckily this has only happened in my work parking lot and not when merging onto traffic or pulling out of my driveway, etc.. where it could be a major safety concern. I have a concern with the clutch is very noisy and rough when engaging/disengaging, it feels as if something is loose or not working properly. This noise worries me, as I don't recall hearing/feeling it on the cars I test drove before this purchase. This next issue is an odd problem but a problem non the less, I have had my emergency flashers turn by themselves when I adjust my ac/heat settings, this has happened a few times since purchase and is annoying. The most recent problem happened last Sunday when I was on the highway in 5th gear, I went to accelerate but the car didn't go anywhere, the rpms increased however the car did not move faster.. it seemed to not have power after 3K rmps. I shifted into 4th and tried to accelerate, same thing, no power. I shifted back into 5th and continued to drive home worried about my cars health and my safety..... few minutes later the check engine light came on. Thankfully, I made it home with no problems.but the car is still not running right. I am bringing the car into Ford this Wednesday and I will let them know about the problems I have been having. More information to follow.

2012 Ford Mustang boss 302 with 4500 miles on the car. The clutch pedal sticks to the floor at high RPM only on the 3-4 shift. The pedal just hangs making it impossible to get the car into any gear until the rpms fall and then the clutch pedal will suddenly spring back to the fully released position with an audible sucking sound. I took the car to the dealer and they claim to not be able to replicate the issue. Every single time you try to shift at high RPM 3-4 the problem happens. The dealer also refused to perform the transmission fluid swap tsb to fix the crunch on 1-2 and 2-3 shift when the transmission is cold.

  • 1,100 miles
I own a 2012 Mustang GT with manual transmission. The car has exhibited very rough shifting about a week after purchase. Additionally the clutch and drivetrain are very noisy - lot's of clangs and seemingly loose parts. The car will pop out of gear occasionally when in 1st. Shifting from 1st to 2nd is sometimes smooth, sometimes very rough and sometimes grinds. Attempting to shift into 2nd when making a left hand turn seems to make rough shifting worse. I was at a light making a left turn on a four lane road. I was in the left hand land with a tractor trailer to my right. The light changed and we both started moving. I tried to shift from 1st to 2nd and was not able to engage the gear and lost speed. The tractor trailer however continued with the turn and had to slam on his breaks to avoid side swiping my car. If the driver hadn't reacted, he would have hit the car. If I had a passenger in the front seat and had been hit they could have been injured or worse. This car is equipped with skip shift technology however the dashboard message that lights when it is active did not light. This car has a serious safety issue which seems to be getting progressively worse. The first time the car was brought to the dealer was for the noisy clutch/trans - they felt it was "louder than normal" and after discussing with them they felt it would not break down. With this most recent issue of not being able to shift into gear and a near-miss accident, I'm scheduling the car to be serviced. This is in my opinion primarily a major safety flaw and secondly a red flag for durability for the life of this drivetrain. A transmission that is grinding gears / getting locked out of gears after a couple of hundred miles can't last for what you would normally expect a transmission to last for. Over the life of the car, how many more situations where you need to maneuver the car to avoid an accident will arise. How many of those times will the transmission not respond?

2012 Mustang V6 manual 6 speed transmission. Hard to shift into 1st gear. Stopped at a red light on pch and topanga canyon with my 3 year old in a baby daughter in the baby seat in the back behind me. I saw a driver behind me coming in too fast. I started prepping if I had to move forward into the intersection that had no traffic just in case. Would not shift into 1st gear no matter what I tried. Quickly I shifted into 2nd and saw the driver smash the breaks while his tires were smoking as he was approaching my rear end in a slide. Car had enough power to move me forward 10 feet and avoid a collision.

2012 Mustang GT 5.0 1.merging onto the freeway, could not get the car in 2nd gear. 2.this happens all the time. And could be deadly, 1 of these times, if the drivers don't recognize I can not accelerate up to speed, because im stuck trying to get my car into gear in a panic. 3.nothing has been done by Ford or the dealer because the say nothing is wrong and it is normal!

Mustang 8-cyl

  • 295 miles
Brand new 2012 Ford Mustang boss 302, 5.0L, MT82 6-spd transmission. My understanding is this car has a revised clutch mechanism vs. The 2011 model year. Regardless, I've begun to experience the same issues 2011 model year owners report. I've owned the car less than two weeks and with less than 200 miles on the car at a stop light the transmission failed to engage into first gear fully. This results in a grinding coming from the transmission. Nearly rear ended, vehicle was at a light at the end of a freeway ramp and was unable to accelerate until the car was placed into neutral and re-shifted to 1st. 1st to 2nd and 2nd to 3rd shifts tend to be hard, rough or clunky. On occasion shifts to 5th exhibit a clunky sensation as well. At 295 miles was unable to shift into 2nd gear, you could hear the synchros winding up in the transmission during the attempt. Likewise moving back to first, even at speeds of less than 5mph in this instance, resulted in a rough engagement and synchro whine from the tranny. Driving in 2nd gear at 20mph and pushing the clutch in to coast results in a rattling noise intermittently. This rattling just started within the last 50 miles of driving. The build date on the vehicle was 3/31/2011. I've not yet reported this issue to my Ford dealer but intend to shortly! very very worried at over $42,000 this is the most expensive vehicle I've ever purchased and am gravely concerned I may have a lemon on my hands. My previous Mustang with a 5 spd manual never exhibited these tendencies. Ford must resolve the issues the mt-82 6 speed transmission immediately or replace it with a properly designed alternate unit. I won't entertain having my special edition vehicle damaged due to a faulty transmission. Likewise I understand the fix offered to 2011 owners only makes matters worse, I refuse to try anything that will worsen the current situation. Deeply fearful that continued use of my 2012 vehicle will result in considerable drivetrain damage or accident.

  • Manual transmission
  • 700 miles
I currently drive a 2012 Ford Mustang GT coupe (this site will not let me select a 2012 Mustang from the drop down menu, only 2011), purchased 3/11/11. It is currently experiencing a "clutch stay out" problem. It is a six speed manual transmission. When shifting from first to second gear at high RPM, the clutch will not release for the shift until the rpms fall back below a certain level. I am unsure if this holds true for all the gears as my car is still fairly new and in break-in and I haven't taken any gear past 5K RPM. That said, the physical experience goes like this, "take first gear past 3K RPM, shift to second, car bucks, rpms fall, second is then engaged, car lurches/lunges forward after the clutch "catches" and then it launches one forward unpredictably." This has happened to me every time I have shifted the car into second gear after taking first gear past 3K RPM.
