Tl* the contact owns a 2011 ford mustang. The contact stated that the front passenger side and rear window tint were deteriorating. The tint was impacting visibility and was removed on the front passenger side. The rear window tint was not removed and needed to be replaced. The vehicle was taken to an authorized dealer multiple times, but no remedy was provided. Upon making a turn or while traveling at any speed, the gears downshifted too fast. The dealer replaced the transmission, but the failure recurred. The manufacturer was notified. The approximate failure mileage was 29,000.

Mt 82 6 speed transmission failed to down shift properly creating a near miss situation due to driver not being able to select lower gear to power up to exceed or at least match the speed of on coming vehicle. The on coming vehicle was a semi traveling 55 MPH in 55 MPH posted speed zone. Had the vehicle performed properly sufficient speed would have been achieved as to not impede the progress of the approaching semi. A reasonable and acceptable amount of distance was present prior to pulling out into traffic. Dealer was advised and performed a change of fluid to a duel clutch fluid which and I installed an aftermarket shifter (mgw shifter) which made a slight improvement. I still believe a design issue exists. Placement into gear is often difficult and up shifting is not smooth as it should be. This transmission has done this on multiple occasions. I am not sure how many complaints there have been but this transmission defect in the 2011 mustang is common knowledge among mustang web sites and forums. The general feeling is ford has not been as aggressive as they should be to find a solution for this issue.

At 150 miles on the odometer the transmission began to grind second gear while turning left. I took it to the dealer, and they changed the fluid as per t.s.b. There was zero change. I took it back to the dealer, and they said it was normal and was a 'break in' issue. Despite disagreeing I drove it until there was around 10,000 miles on it. At this point it was nearly impossible to shift into second when turning left without physically forcing it to the point I was skipping to third. Also third gear had developed the same issues intermittently. I took it back in, and they bled the clutch. After receiving the car I took it back the next week, as obviously it did not fix anything. Ford decided to replace the transmission. The technician reported all syncros and blocking rings were extremely worn and second and third gears showed signs of wear. He also reported the input shaft bearing had showed signs that it had been very hot. After receiving my car back I noticed a difference, now the shifter linkage had a noticeable popping/binding feeling in the linkage when moving the shifter back and forth in the nuetral position. I was informed that it was abnormal, but that other cars on the lot had the same issue. Which later I found out to be a lie. After about 100 miles it has shown the same exact symptoms as before including the new linkage issue. I drove the car with the technician with me for an extended period of time. I was able to duplicate the issue when turning left. The technician was also able to notice this issue when he was driving. Even though it happens only when turning left and only when changing to second gear, he again lied to me and told me that it was normal, and that in all cars you have to wait a little bit for the syncro's to catch up and it is normal to have to wait a few seconds while holding it up to the syncros for it to slide in. Please contact me.

Heading up a hill and heard a loud grinding sound. Car stopped in place and would not go anywhere when pressing on the gas. Tried putting the car in reverse and would not move at all. Also tried putting in neutral and it still would not move. Had car towed to ford dealership and the service department checked the car out and stated that the transmission "grenaded" as it stated on the work order. I got to see what the transmission looked like. It had pieces of metal everywhere and the long bearings were all shattered into pieces. A new transmission was ordered and placed in the car.

If I take my foot off of the gas the car seems to lower it's rpms by itself almost to the point of it feeling like it is braking without any help from me. This happens pretty much at any speed. Also there seems to be an issue when slowing/stopping and accelerating. When I start slowing down and then have to press the gas the car jolts like it goes from 1st gear to 4th gear instantly. This is not a good feeling at all and kind of scary. It almost feels like the car is going to take off without me. Had this issue before and after the transmission was replaced at 1500 miles.

This issue has been going on for roughly 6 months (I have owned the car for almost a year as of this writing) when the vehicle is in motion, shifting from 4th to 5th gear causes a loud grinding noise. The clutch pedal was fully depressed at this time. This occurs at least once a week. Also, at one time the shifter got stuck between two gears when stopped at a stop light when trying to shift from neutral to first. At this time a car could have run into me while I was trying to get the car into gear. So far I have not taken the car into the shop to correct the failure, as I have learned ford does not do anything to correct it. All they do is replace the transmission with the same defective part and/or put new fluid in. I am waiting to see if they will issue a recall and perform a proper repair for people who are running into these symptoms on the 2011 ford mustang gt's.

1. This event has happened twice in the 3 weeks I've owned the vehicle. This occurred in a normal driving situations. No extenuating circumstances. 2. The transmission will not go into first gear. I can't get out of someone's way at a light. It also will not transition into second gear, even with a throttle blip. When this happens the vehicle begins to coast and I have to fight with it to get into gear. It's distracting and frankly nerve racking. There are times when transitioning from reverse to first gear, the transmission grinds. On coming to a stop, the transmission will vibrate violently. It almost shakes the shifter out of your hand. 3. I called ford. They gave me a claim number. Ford did not offer any advice about this issue. I have to schedule an appointment with a service tech. However ford is not guaranteeing that I will not have to pay out of pocket for this inspection. It's almost like a threat. If nothing is found to be wrong with a brand new transmission, I am culpable for the cost. Ford offers no rental, so this compounds the issue.

Our 2011 mustang gt with 6-speed manual transmission has a terrible notchy shifter that I've complained about 2 times to my dealer. The first time they replaced the clutch, and the second time they replaced the transmission fluid according to a tsb from ford. I read the tsb online and it says it's for cars with difficult shifting in cold temperatures (which isn't my issue) but they insisted this would fix it. Immediately, the shifting was worse and I'm having trouble getting the car into reverse, second and third. When you have to get out of the way quickly, you can't get the car in gear and this is really starting to scare me. The dealer claims there is no other fix available so I asked them to give me a new car (mine only has 1400 miles on it) and they said "no, they all do this" and implied I'm not shifting correctly, I've bee driving manual transmissions for 40 years. I know how to shift. This problem is all over the internet. Why aren't they recalling this before somebody gets hurt?
