Noises During Shifting problems of the 2012 Ford Mustang

I brought my 2012 Mustang gt with a manual transmission in to be serviced because of an awful noise occurring while shifting in and out of 5th gear. The service department now says I need a new transmission at 38,000 miles.

I was driving @ 60mph down shifted from 5 to 4 and lost all power from the trasmission and the clutch became hard to push. The engine did not shut off. I did not hear a noise of any sort. I had to call and get it towed. I have not gotten a diagnosis yet.

Problem: abnormal vibration/noise in stick shift/driver seat during deceleration. Car: 2012 Mustang v6 base model (no add on's) manual 6 speed. Purchased new. Had control arms replace within 2 weeks of ownership due to creaking front end (392 miles on the car). Approximately 3 months after control arms were replaced I noticed vibrations in shifter and driver seat as well as rumbling noises when on highway during deceleration. Sounded and felt like when you ride over a rough patch of pavement or a metal grated bridge. Problem continued off and on and I could not duplicate. I have recently been able to reproduce the problem. What I discovered was when I ran the car up to 2750-3000 rpms then let off the accelerator I could feel an abnormal vibration and hear the car rumbling. The vibration/noise would stop as the car decelerated to about 2500-2000 rpm's. Severity of vibration/rumbling noise has ranged from mild vibration/noise to stick slapping back and forth violently and very loud rumbling. Car does this in 1st, 2nd, 3rd and 4th gear. I don't get to 3000 in 5th or 6th gear so I don't know if problem exists in these gears. Road conditions do not appear to lessen or increase rate of incident.

As I was turning a corner from a red light I went to shift into 4th gear it would not shift at all almost causing me to crash. This transmission locks rarely locks me out of gears but this time was the worst. I also have many grinding noises from 1st-2nd-3rd gear. One time I went put it in reverse and it popped out. Another time I was at a stop light and put it in first went to go and it grinded the gears really loud then it popped out lucky it was at night an no one was behind me. Multiple missed 3rd gear shifts as if it is locking me out. This problem keeps getting worse and worse the more I drive it and I only have 1100 miles on the car. This is not fair and this transmission needs to be recalled complete garbage. Please do something about this. Thank you!!!.

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!.

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.

I bought a 2012 Mustang gt premium in April. Starting at about 2000 miles, my car has had a large "thunk" when shifting from 1st to 2nd gear, occasionally causing a "lock-out. " usually, this lockout occurs at low speeds (I. E. Under 15 mph) or occasionally will occur when stopped this issue has been reported to the local dealership a total of 3+ times, with the first action being a replacement of the fluid per the TSB. While this improved the issue, it did not resolve it. The second time it was dropped off, one of the service consultants recognized the issue. I removed the car from the dealership since I was going on a long vacation with the car. After dropping it off the third time, the issue was recognized again (after much delay). The dealership tested another car of similar miles, which was "notchy" but not to the extent of my own vehicle. Regardless, it was not found to be "excessive. " I escalated my claim through a Ford service rep who subsequently called and explained that it was not "excessive" enough and that the dealer could not replicate the problem to the extent I experience. I proceeded to request a test drive with the other vehicle and noticed the similar feel, but none of the noise or "lock-out. " I agreed to drive another collection of miles, but the lock-out is still present at regular intervals, leading me to believe this is a systematic safety issue.

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.

The contact owns a 2012 Ford Mustang. The contact stated that she was unable to shift between third and fourth gears and would hear a loud grinding noise from the vehicle. In addition, there was smoke coming from the vehicle abnormally. The vehicle was towed to the dealer and the transmission was replaced yet the failure recurred shortly thereafter. The manufacturer was made aware of the failure. The current and failure mileages were unknown. The VIN was unavailable.
