Unhappy Complaints on the 2011/12 Tranny

Continuously reading about the clutch issues. I just purchase a 2012 at the end of October. Only 790 miles on it now. Now when it is cold going into 2nd gear is notchy or a little rough. But, when it warms up not as bad. But, research it more and found this below on the government site for defects and complaints. I'm 45 years old and wanted my own mustang since I was 15! My husband has a 87 5.0 he ordered brand new. No problems great car. I had kids and had to four door it. Now oldest son is 21 and youngest is 12. Finally got it, now this. Big Ford family. 99 F-250 CC 4x4 Diesel, 2001 Explorer sport and the two 5.0's.

The beauty of owning a new car is the warranty! if you are having issues and concerns take it to the dealership or contact Ford directly. The issues involved in the NHTSA are far from what you are experiencing. Don't allow a few cars with issues to put you into a frenzy and also the 1,000 of bandwagon posts in regards to this issue. Read Ford's response to NHTSA inquiry.

This item was actually addressed under a TSB where the dealer puts in a different gear oil. The OEM stuff is too thick (or wrong specs) for cold weather driving which makes it hard to shift.

Oh and Ford and NHSTA did an investigation and found that some of the stories (like almost crashed etc) were made up.

Do a search on the site and you'll find the thread with all of the details.

Ignore the government report - it's a result of problems that Ford has pretty much fixed in the 2012's. There is one minor adjustment they made in late summer for cars produced after August 25th that yours might not have, and your dealer can change the transmission fluid to a thinner one (that's what changed on August 25th) to make the notchy shifting smooth again.

Motor down to the dealer and talk to the service writer and tell them you have difficult shifting when the gearbox is cold.

I read the complaints myself. A lot sounded pretty legit. And they were 2012's. GT's and Boss. I have read on other forums too about the problems. If it does keep up I will take it in and get them to change the tranny oil. Thanks.

Also, I take it easy on it driving around town. I am getting only 14 mpg! Is this the norm? God, everytime I turn around it seems I'm filling it up. Even the Corvette z06 with a chip added (borla pipes) I had gets better gas milege than this thing! And it had lot more horses! I am thinking of putting a cold air intake on it to help with gas mpg and get it tuned ( Airaid or JLT)? My idiot brother n law said his 2500 diesel crew cab truck with bully dog will beat me (it is pretty bad, smokes the tires taking off good!). Huh, his is a lot heavier, geared different and the torgue different.

Thanks for ur help and any advice!

If you have a manual you need to skip gears (1-3-5-6 or 2-4-6) to see decent MPG in the city. I very rarely start off in 1st as 2nd is more than short enough to get moving in.

Also, if your car has fewer than about 3,000 miles, MPG seems to be awful. Mine suddenly got a lot better at around 2,500 miles. I average 17-19 in the city (depending on how many lights I catch) nowadays - but when the car was new I'd be lucky to get 14.

I haven't had any issues with my 6 spd in my 2012 but I too was getting horrible gas mileage.

I was averaging 14 mpg the first 500miles but it does seem as the mileage adds on and the motor fully breaks in that it will get better. I have 3.73 gears just passed 1000 miles and i'm getting about 17 all city now. Skipping shifts does help alot. I can use 6th as early as 30mph.

Ford's been making 2012's since January 2011, and most of the fixes were done in production starting in February through about May, with the last one at the end of August. Check your door jamb and see when yours was made.

There is a category of shifting complaint that I think is separate from the gearbox issues, but that folks always mix in anyways. The stock shifter linkage seems to have some manufacturing variances and some cars, not many, have problems shifting at high revs or under high lateral G's or under heavy braking. Under normal conditions they shift just fine. In my opinion, that's a linkage issue not a transmission issue, in that even if you install a new transmission, it still won't shift properly. However, before rushing out to get a new shifter (MGW is good) make sure the fluid's the right one for the job.

As for gas mileage, it improves as the engine and drive train breaks in. I get about 18 MPG with a mix of city and highway driving and 25 or so on the highway.

Shifting and gas mileage seem to improve with miles on my mustang. You definitely have to use skip shift to get better than 17 mpg. Another thing to check is the oil level on your mustang during the first 500 miles. I have to put in a quart right about 800 miles. I was told the oil consumption will improve as the car breakin, I haven't confirm that yet.

The mileage is directly related to the fun you are having with your new car! Ok, yes, there is some seating of the rings that improves things, but you also have to take into account that the EPA fuel economy is shifting at 2k rpm. I rarely shift below 3k because I like the pull at the bottom of the powerband.

Oh, and my 2011 6spd is working flawlessly, aside from the cold temp issues. I'll ask them to act on the TSB when I go in for my next oil change. I'm coming up on 12k miles now.

There are a lot of people that can't handle thinking the 30+ thousand dollar car they bought has problems. While people discuss issues, there are others who completely deny the problems.

I have a 2011 5.0, 6 speed, and I'm having quite a few problems. I just hit 5,000 miles and first to second is ridiculously rough. I've had problems getting it into second at all, and in traffic that is a big deal. My clutch engages at different points every day, and with such a mushy clutch it is extremely difficult to get a smooth take off. Some days it engages an inch off the floor, other times it's 3-4 inches.

My dad is a tech at a local ford dealership and we plan to take out the transmission and look at a number of things, because there are a number of complaints in this forum alone.

I am sorry you are having so many problems. I watched a Youtube video showing these guys that video taped their problems (brokenstangs.com). One 2011 was shaking so bad. Scary! Yes, these things aren't cheap. What a difference when we paid $17K for our 1987 Mustang GT we bought brand new! I wish you luck!

Ya, I just checked my oil levels and had to add 2/3 of the bottle! And it only has 873 miles on it now! I will just have to keep on top of that. Thanks for the input!

Every new ford I have driven so far was really bad on gas for the first 10k or so.

Examples,
My then new 2007 Mustag gt (RIP. That's why I have a rental focus. Its totaled)
first tank of gas? 11mpg... That was taking it easy never shifting above 3k
after 5-6k 16-17 in city, 25-28highway

Rented Edge. MY unk rented one to drive cross country.
Picked up with 200miles on the odo, averages 17-18mpg on the highway.
Droped off @ 8k miles after a month. 22-24mpg highway after 4k miles.

My rental focus, picked up with 12k on clock.
32mpg combined. Not bad. But got better.
Now @ nearly 15k, 38mpg easy as much as 43mpg on highway.

Reason for this is two fold. Its not just the rings seating, there are allot of moving parts in a 32v dohc vvt engine. They all need to create their own wear pattern and the tolerances are very tight. Also the type of steel ford uses for cylinder liners seems to be high grade highly tempered stuff.

My Unk rents a car once yearly around dec to drive across the US with. For comparison.

Chevy Traverse. Engine broke in less than 2k miles.

toyota highlander broke in less than 1k miles.

He is a 30+ year veteran trucker, he drives by ear, and he simply said the ford motor was the hardest motor to break in he has ever done. And he has owned many a 4 wheeled vehicle with gasoline and diesel engines.

I feel for all those that have had problems with their trannys. It's certainly not cool to have problems with your brand new vehicle. But to the OP, I wouldn't worry too much about clutch or tranny problems. Just drive your car & if you notice anything wrong, simply take it to the dealer. I worried a little when I picked up my '11 that I ordered after reading about clutch problems others were having. I'm happy to report that I've had zero clutch problems and my tranny shifts nice and smooth.

Angry 1st to 2nd gear stiff

Well, took my 2012 Mustang GT (bought at the end of Oct. it was built in August 2011) in because was tired of 1st to 2nd feeling stiff/notcy. The service tech drove it and change the tranny fluid, via the TSB on it. Well, this is the second day after it was done and it is still doing it of and on. What the hay?

Also, I only have 1200 miles on it and have put two quarts of oil in it since 800 miles. Someone said on here before that it is normal break in? Someone at Ford today said that I need to bring it in?

I'm supposed to take my car Tuesday to the dealer. I just bought it used, I thought I will check the fluid level but they say it is a sealed tranny. I hope the tech find the problem, it is notchy and I'm hearing a whine also

The TSB fixed mine completely. If the TSB fix didn't eliminate your rough shifts, take it back in for sure. You definitely have other problems than just the tranny oil.
You could have a bad batch of parts inside (poorly made shifting forks, synchros, etc.) or the bolts on the flywheel could be loosening, or whatever.
The Ford techs can tell you for sure, and by doing so, once they find out what is going on, and not only that, once they find out for sure, they will have documented proof of what else these trannies could suffer from.

My 2012 GT seems to have increasingly hard shifts starting with 1st being the worse and getting better through the gears. It feels like Im getting to the point of forcing it in first when creeping.

I have no issues at a full stop so I am thinking syncors. I have 7900 miles.

Was thinking of getting a shifter to perhaps make it easier but would this void the warranty? I don't want to give them a reason to bull**** me.

The first thing you should do is take it in to the dealership to fix as per TSB. If you are worried about a shifter causing you to be denied for tranny warranty work, dont get one yet. Make the dealer fix te shifting issues first.
