Noises During Shifting problems of the 2011 Ford Mustang

The Ford vehicle showed the following signs at the time of shifting into higher gears, transmission failing to synchronize, slow reaction, harsh shifts, grinding gear noises at low and high rpm.

When shifting from 1st to 2nd gear transmission will not shift, it must be force into 2nd gear. Also 5th gear grinds at normal highway speeds. Vehicle will not shift into reverse unless engine is off, must shift to reverse, start engine and then vehicle will move in reverse. While driving there is no vibration, nor whinning noises. Once vehicle has been shut down and engine is cold, can not shift into 1st gear, after vehicle has set over night, can only place into 1st gear before startup.

The clutch makes a cracking noise. When I shift between 1st and 3rd it can be difficult at times depending on the temperature. The symptoms are not consistent.

€¢ transmission notchiness • occasionally unable to get into gears (not due to skip shift) • clutch makes occasional clunking noises especially at low speeds • cold shifting exacerbates problems (will be taken care of by TSB) dangerous experiences: • November 18th: I was accelerating onto the highway to merge with traffic. Attempted to shift from third gear to fourth gear as I was passing a semi. I was unable to get into gear (shifting correctly: clutch depressed, calm smooth gear change), and I was forced to drive off the road at 35+ mph. This life threatening experience moved me to take these actions. €¢ December 5th: as I was taking the vehicle to a dealership for the third repair attempt, I was turning left at an intersection and had to shift from first to second (at 2000 rpm so no skip shift issue). I was unable to enter the gear and was vulnerable to accidents being stuck in the middle of the intersection for several seconds. I finally shifted into the second gear with a loud grind, avoiding a collision with a bus.

Car: 2011 Mustang v6 with manual transmission miles: 3600 the problem: the gear shift is very notchy and rough, especially from 1-2 and 2-3. There have been times when I wanted to make a left turn at a light and mistakenly gone into third gear from neutral because the gear refuses to go into 1 easily. So I end up not having enough acceleration to beat oncoming traffic. I have almost had three crashes this way. Other times shifting from 1-2 or 2-3 causes an incomplete shift because of some resistance in the gear box. This leads to a jarring, loud grinding noise emanating from the gear box. This also leads to loss of acceleration and I have been almost rear ended a few times. These problems occur on and off mostly when starting off from a stop (from neutral) and at high rpm gear changes. Resolution: I've taken the car into the dealership and they changed the transmission fluid as per the Ford TSB. This fixed the problem for a mile and the problem started occurring again. I took the car in again on the insistence of the service manager and he drove it around and acknowledged the issue as well. He said he would get in touch with Ford to see if there was any fix. He got back to me a few weeks later and said that Ford doesn't have any resolution and doesn't seem to even acknowledge the issue. Final thoughts: I think the trasmission problems is an accident waiting to happen. I am extremely disappointed that a new car has these issues. It is a great car otherwise. Ford needs to acknowledge the issue and fix it soon. I've also found that some 2012 Mustangs have the same issue with the gear box. It is appalling to think that the company would continue to use the same transmission parts in spite of the issues in the 2011 models. This is amounts to a blazen disregard to consumer safety and experience. I strongly suggest the NHTSA pressures the car company to fix this issue and if no such resolution is forthcoming to force them to issue a recall. Sincerely an unhappy Ford driver.

Since the car has been in my possession, 3rd gear has always had issues. It grinds from time to time, and the transmission pushes me out of 3rd gear when my foot is completely down on the clutch. It has also developed an increasingly loud whining noise throughout all the gears while accelerating. The shifts when cold are rough, doesn't feel as it should.

Loud whine from under hood area, possibly mt82 manual transmission, heard from 2. 5k-3. 5k rpms and in gears one to four when up shifting. Whine only heard when car is in motion. Whine is not heard when in reverse gear. Clunking noise can sometimes be heard with 1st to 2nd up shift and is somewhat difficult to shift at times. Engagement of gears can be audibly heard and 'felt' in the drivers seat during the rough 1st to 2nd shifts. Have had this trouble since new with 112 miles on the car starting out. Now car has approximately 275 miles. Whine noise has become noticeably louder over a short period and more frequent already. 1st to 2nd hard shifts becoming more frequent even over short period of time. Regardless whether car is warmed up or not, whine and hard shift frequency seems unaffected. I have not ran the engine speed over 4k rpms since purchased. Have reported to the service department at cavalier Ford of chesapeke, va, left cell and work number including work times and have had no feedback as promised from any tech as of the time of this writing. I have read and heard of many 2011 Mustang owners with the manual transmission having these same symptoms; sometimes with dangerous results on the road.

Problems shifting car into gear. Gears are notchy and almost impossible to shift into first when car is cold. Transmission making whining noises in 1-4 gears.

Rough, irregular shifting, most noticeable shifting from 1st gear on this manual transmission. Seems to lock you out of gears at any given time. Also while down shifting, I. E. Exiting off the highway onto an exit ramp, have experienced a similar problem. From 6th gear, the transmission locked me out of 4th gear and forced me into 2nd gear. This caused a massive and sudden decrease in speed causing the vehicle behind me to slam on their brakes in order to avoid rear-ending me. Persistent grinding noise and feel while the car is being shifted, as if the gears are not meshing when shifted. Noticeable in the feel of the stick and audible at times as well. This is noticeable in most gears in particular 2nd thru 5th. The transmission constantly makes a hard clunking noise when it is put into first gear from neutral. This clunk can be heard and felt in the car clearly. I've had this vehicle to the dealer several times, keep getting the run-around, I. E. , "that is normal", "our tech's couldnt reproduce the problem" etc. . . Standard dealer deflection.

The contact owns a 2011 Ford Mustang. The contact was driving approximately 10 mph when a grinding noise was heard from the vehicle. In addition, there was a delayed response from the manual transmission when shifting into second or third gear. The failure recurred when driving between 10-30 mph. The vehicle was taken to an authorized dealer where the old transmission fluid was removed and replaced with a higher grade. The failure continued to recur. There was a technical service bulletin under NHTSA action number: 1003914 (power train: manual transmission) that was possibly related to the failure. The manufacturer was not notified of the problem. The approximate failure mileage was 10.

The contact owns a 2011 Ford Mustang gt. The contact stated that when attempting to shift gears manually from first to second, the vehicle would skip second and shift into third gear, distorting the vehicles speed. Also, when shifting from first to second gear, the vehicle would exhibit a clunking and grinding noise. The dealer was notified of the defect, but the vehicle was not repaired. The failure mileage was 2,000 and the current mileage was 7,500.

The contact owns a 2011 Ford Mustang gt. The contact started the ignition and when shifting from first into second gear a roughness in the response occurred with an unusual noise. The vehicle was taken to an authorized dealer who stated the transmission operated properly. The manufacturer was notified of the problem. The approximate failure mileage was 75.

Since the first day that I bought this new Mustang, the automatic transmission shifts hard and there is a clunking noise. This happens mostly when slowing down and then starting to pick up. Also when just slowing down and the car shifts to 1st gear. The shifting is erratic and noisy. When the engine is cold, it also bangs into 2nd and 3rd gear. The dealership checked it out and said that this is part of the computer programming and is the way the transmission was designed, until it gets used to my driving habits. That was 17, 000 miles ago. They said there might be a computer upgrade in the future. In the meantime I fear a rear end collision when I am unable to pick up speed because of the hesitation and clunking.
