Ford Mustang Transmission Problems
I have a '07 Mustang GT/CS with manual 5-speed. It feels very stiff to me but I have nothing to compare it to. Is there an adjustment or something that can be done to change this ?

One thing you can do for not a lot of money is install a Hurst competition shifter or a Ford Racing Shifter. The Hurst shifter goes for under $200 online and is a 45 to 90 min install.

Thanks for the reply. I know nothing about cars so your advice is appreciated. I know the engine is capable of 320 ft/lbs of torque but with the clutch depressed does that really come into play? I had another friend suggest the same thing. I'm afraid I don't know how to install a Hurst shifter myself so I would also have to pay someone to do it. Will it really make the shifting easier/smoother?
Thanks again for the help.
The manual trans components are big and beefy to handly both the stock torque and any additional from reasonable mods people might make.
Thease big beefy parts have more mass and just plain old take more effort to move. You can't compare this to a shifter in a Honda Civic etc.

Thanks again for the info. The last time I drove a stick shift was in 1967. It was a 1962 VW Beetle.

1st and 2nd are double syncroed. The wet clutch is hevy duty. The Mustang is not a tame pony.

Also, while shifting from 1st to 2nd I hear a clinging, metal banging like sound. The dealer said it’s also normal. Is that true? It seems kind of weird that this car should be making so much noise during shifting and its brand NEW!!!. My friends Mazda doesn’t make a sound during shifting.
Is anybody else experiencing these problems?
Thanks for your help

After 05, the trans is mounted 2 for forward for this setup and there is shaft linkage.

Sounds like a possible throw out bearing. Any clutch pedal vibration? I mean real vibration while in gear?
As for normal gear noise, unless you replaced your shifter with a tri ax, etc. and didn't install the silencer back it should not be that loud of a sound. Tell the dealer to fix it, or they can have your car until it is fixed.
Good luck.
My bad. didn't read the last page of posts.
New here, and my first post, but probably my last as well. I am a member of more forums than I can keep track of.
Anyway to the point of my post-The info I am providing here ONLY applies to GT's with 5 speed transmission; not the GT500s or V6s...
First, I LOVE my car. I have been coveting them since they first came out. I only wanted a Legend Lime one. It was just never in the cards for me, until about 6 months ago when I finally picked up an 06 with 4200 miles on it.
I have only owned 2 other sticks in my life, but have driven a few more, and after the initial excitement of my new car wore off, I started noticing the "feel" of the shifting in my car was very inconsistent. Maybe sports car trannies are supposed to feel like this, but I am used to smooth-as-butter, consistant shifting. On my car one shift it may drop into gear as smooth as butter, and the next time it might feel "notchy", or like it didn't *quite* go in smoothly; almost feel a "bump", push a little further then a second "bump" when its fully engaged, and sometimes resistance is felt all the way into the gear.
Also on a few occasions, when shifting from 1st to 2nd I was greeted with a nice "clunk"-not really a gear grind, but close. In the cases of the "clunk" it was a cool morning, and I just started it up and drove off, and it only happend on the first shift of the day. Note, that for me (and ALOT of folks as well) once the vehicle reaches normal operating temperature, the "clashing" or grinding is not a problem. It shifts fine once at normal temp, although its still inconsistent feeling-sometimes its smooth and drops right into gear, other times resistance is felt.
Growing a little concerned, I did ALOT of web research. Bottom line, there isn't much on the 2005+ mustang's , but...
There is a weath of info on our transmissions, which in the GT happens to be the Tremec TR-3650. There was a TSB on the 2001-2004 mustangs for the VERY symptoms I am describing, and a few others as well. Supposedly these issues were fixed by the TSB, on some occasions by a fluid change (Tremec revised the fill quantity/oil type over the years in this tranny), and surly it was fixed by the 05 models.
Obviously not everyone is having this issue, as there will no doubt be a poster or two that says "I've never had any problems with mine", but evidently the issue has not been totally resolved as there are a few people out there that I have read about on the net, or spoken too that have had similar stories.
The good news is, your not alone-doesn't happen to everyone, but yours isn't the only one that does it, and according to the dealer, they *say* its okay and no harm will come to the vehicle. The bad news is, if they haven't fixed it by now for a problem that started to surfice since the day they started using these trannies in the GT, I don't expect a fix anytime soon.
For more information, you can see this thread (very long, and it *technicly only applies to 2001-2004 GTs):
http://forums.stangnet.com/showthread.php?t=328655
Or, you can do a websearch for "TR3650 cold clash".
Although the two links I provided above do not apply to 05 and up stangs, I have also read (can't find the links now) of at least 3 others with similar stories. One person in his signature mentions that he traded his 05 stick for an 06 automatic and says "YES, automatic, and loving every non-notchy, clashy feel of the shifts".
Don't know if this helps anyone out, but thought I'd share.
Note, the GT500 uses a different transmission that is double synchroed, where as the regular GT tranny is NOT double synchroed.
Now, the only question I have is...
Will changing the shifter to a different one change the "feel" of the shifts? I am considering doing it, but not sure of the results. If the "shift issues" are internal in the transmission I can't see how a different shifter will magicly make it feel smoother, but on the other hand, the shift mechanism in our cars are remotely mounted, and due to engine/transmission twist and movement, could cause some of the odd shifting feel as well, but I just don't know.
Although other posters in that thread are leading the OP towards an exhaust sound, I think its obvious that what the OP is feeling is the transmission; why would an exhaust sound only occur between 1st and 2nd gears?

Other than that I really love my car:

I know my reply was long, but the point of my post was although probably not technically "normal", there are many others whose transmissions feel exactly as you describe, so in that sense...it is normal, if not irritating.
Guess you could say it is ford's problem, but ford didn't build these trannies; Tremec did, although they are almost exclusive to the mustang (there are no other 5 speed longitudal domestic vehicles in production today).
Anyway, I do hope my info helped someone; at least if not to set the mind at ease, at least to shed light that you are not alone.
Personally, the shifting is irritating at times, but otherwise I LOVE my car, and don't plan on getting rid of it just because I don't like the way it feels sometimes.

Happy Holidays !
I have a 2007 V6 5 speed, and it has all the same issues. Clutch replaced, Trannie replaced, the TSB for the exhaust was completed, and that is only the start of my list. After all this, it still has issues, and the longer I drive it the worse it gets. All the vibrations are still there and get worse everyday. After less than a week, the new clutch is having the same issues all over again. Once more the clutch petal does not disengage after being pressed. The list goes on and on.
I just want to make sure everyone is up to date on this issue. It is a problem, and if you are dealing with it, take it to the dealer until they fix it (if they can). Don't just accept it and think that it is normal.
This is also a warning to anyone out there that is thinking about buying a used 2007 Mustang 5 Speed . If it has low mileage, and there is even a hint of vibration or shifting issue, DO NOT PURCHASE THE CAR. Don't listen to anyone that tells you it should sound like that, or that it will loosen up after awhile. This is not true, and if anything, it will continue to get worse the more you drive it. Most dealerships will tell you that there is nothing wrong, so many owners are trading off the cars just to get rid of the headaches.
Hope this helps someone out there!!
I have a 2002 Ford Mustang GT, which is suffering from an automatic transmission problem, and I first noticed the problem about a week ago. The vehicle accelerates normally from zero to about 10 miles per hour and from 30 on upward; however, the problem is experienced when accelerating between 10 m.p.h. and 30 m.p.h. When the 10 m.p.h mark is met, the vehicle begins to accelerate at a very slow rate, while the engine seems to rev out of control as if the gas pedal is floored.
I did a bit of online research concerning the problem, and it sounded as if my car was skipping gears. The vehicle was taken in for a diagnosis of the problem, and the following explanation was given: when putting the vehicle into gear, the transmission shifts into both reverse and forward gears. As you accelerate, it jerks hard, then the forward gear overpowers the reverse and drives relatively smoothly. It does have an intermittent jerk while driving, however. I have been told the transmission would be too costly to fix, and placing a rebuilt one in is recommended; the estimated repair: $2900.00.
I must admit I am a bit ignorant when it comes to car problems, especially when the more complex components are involved (i.e. transmission), so I am trying to be cautious as to not be ripped off. Based upon the explanation I have given, does the mechanics diagnosis sound correct? Should I get a second opinion? Does the estimated repair cost sound fair? Does the problem sound like it could be fixed cheaper rather than putting a rebuilt transmission in?
Any information that is provided would certainly be appreciated. Thank you so much, and I hope you have a tremendous day.

I am having a heck of a time getting it fixed.
So I did some checking around and I got some good feedback about the guys at FB Performance in NY. They seem to specialize in the Ford trannys. I wound up buying one of their 4STB-E transmossions and 9” full race L/U converter. Its based on the 4R70W, but its rated to 900+hp. I got the full manual valvebody with elec OD & L/U and a built-in trans-brake. Last fall I went mid 9’s at 148 on radials and its held up to everything I’ve thrown at it. They even reworked a stock Ford auto shifter to work just like a ¼ stick so everything looks stock. What a difference at 80mph on the hwy! I love it!
Both cars have the cold upshift into second resistance/clunk/slight gear grind. Both get much better when warmed up. Both have sort of clunky feeling shifters (that feel much crisper after driving my manual shift Jeep, it is all relative) and both developed noisy throughout bearings after about 30,000 miles. The bearing still works ok, just makes a low volume high pitched whining noise when the clutch is in use. Unless the bearing quits completely, I will just wait for the clutch to wear out and replace it all at once.
The car is fun, good driver, just a pain to shift into second until the transmissions gets some heat into it. It has never been enough of a problem to do anything about it, so it is still just as it left the factory. That was true for the first trannie when that car got wrecked, also. Sounds like I got the mild version of our problem trannies, but did get the problem.
