I recently got a stock 2007 Shelby GT and I have noticed that under heavy acceleration (approx. greater than 4500) in second gear up to 6000 RPM that a rattling sound seems to be coming from the gear shift. I am not sure if this occurs in the top end of other gears as I usually go from 1st to 2nd to 5th. If someone could help me out and tell me if this is normal or abnormal I would really appreciate the help. If this question has already been asked I am sorry for the repeat. Again any help is appreciated.

Is your hand on the shifter?

I found the same noise on my 2010 GT500 when I first bought it. I realized that I was holding onto the shifter and *slightly* holding back on it. Once I discovered that, I pulled my hand off and never had the sound again (It was ME, not the trans/shifter/car)!

I didn't even realize I had the habit of doing that....

No my hand has not been on the gear shift. Me and a friend but just happened to hear a slightly noticeable rattle. At first I was not sure where it was coming from but I soon figured out that it seemed to be coming from the gear shift and when I did place my hand on it, a slight vibration could be felt. Is this something that I should get checked out or should I just stay away from the top end of the gears?

check your e brake handle mine rattle alittle bit. if its not that then somethings loose. id get under the car and check the shifter mounts.. mine were loose when i got the car. didnt figure it out till i reached up past the tranny and started checking things before a race last year.
having a 9 second ricer is like coming out of the closet, at first you surprise every one but at the end of the day your still gay
man kind has earned the right to rule this planet by occasionally producing someone totally bats#$t insane

this has been mentioned before here. i can t remember where but, searching should bring it up. someone said something about some adjustment screws on the shifter i think.
mine does it. i can just touch it with my hand it and it stops. but i get it in all gears but only under load.
1 finger, slight pressure and it stops.
i did my aluminum driveshaft install and while i was under there i checked the bolts i could reach and all seemed snug. so i so guess i need to do some research as i dont remember the exact fix.

i just did.. do you really think i can just lightly touch the shifter ball and stop that from hapening all the way down there? seems to me like its more direclty related to the shifter since i really truly can just rest the weight of my finger on it and it stops.. thanks for that info though and i found a link that has the full text of that tsb ill try to get underneath this weekend and see if that could have anyhting to do with it.
thank you!

Mine has been doing it in 4th gear under load...about 3000 rpms and up. I had the TSB done for the syncros from 2nd to 3rd by the Ford Dealer under warranty and just after that is when mine started. Just by coincedense, I had them check it today when I was in for a couple of routine items & tires and they said they heard no rattle....looks like I'll have to take them for a ride to show them since I can get it to happen on command.

It is a definite vibration of some sort.

I'll have to check out that other TSB....not sure what that one is or if it is for my vehicle year, etc.

Andy.

Go to the Tech/Mod area and search for "shifter rattle" and you will find 5 years of issues and possible solutions.

There are more than a few causes for this and you'll need to figure out which one(s) apply to your car.

Good luck!

The Hurst shifter linkage on the SGT has 3 o-rings on the shaft where the shifter connects to the linkage
Likely these are to dampen vibrations

Just wondering if the transmission was ever removed?
The o-rings can be challenging when you put everything back together and could be easily pinched & damaged if you're not not careful

I test drove a used SGT a couple of years ago, and the shifter not only vibrated it was sloppy loose
The used car salesman tried to tell me that was normal
He didn't know what to say when I told him not the case, because I owned one already

Mine used to do tho also. The rear shifter bolt was loose (only in a couple threads). Tightened it with some loctite, no more problems
