You're just not driving aggressively enough - more revs and throttle means that nobody can hear the clunks over the engine and exhaust

I think it sounds like a dog toothed race trasmission, I love the look people give me, lol.

Oh and mine whines on deceleration especially in first gear.

its normal for this tranny something to do with the fact that its a high performance tranny.. apprently other high performance trannys do this as well.. or so I have been told.. shift at 3k you won't notice it anymore, or as much.

i get it real bad lol, stage 4 clutch grabs up pretty hard!!!!! big clunks lol.... aint nothin to hurt it though, i mean, what can i do, a stage 4 clutch is just gonna hit hard... its also very noisy at idle... makes a lot of clickity clackity noise... really fast... when i push the clutch in, it stops lol.. people always ask me what that noise is, and i tell them, and they're like, oh, yeah, that will do it...

absolutely, thats why I stated what I did. This is a performance transmission. If any of your ever heard what one sounds like, they whine reall nice and loud!!!

play some forza 2 and install the race transmission for an almost identicle sound to what your car makes

Sure is loud and un-nerving but I figure it kinda sounds like the constantly adjustable pressure plate on the clutch. Our cars have the plate that adjust to how thick the clutch is, so as the clutch wears over time the distance is always the same hence the adjustment, meaning always the same grip.

Mines been doing it since day one.....moving sound are normal.....

At the track, when I shift into second and let it go, it clunks real bad, all that damn torque I think....

My 2 cents? TURN THE RADIO UP!!!

No really. The guys talking about the trans making noises because it's a performance trans are probably close. But I believe the noise is actually caused by the differential and especially if you have LS. The Limited Slip unit is an all gear unit which is a very high performance piece. I't's an all gear (no clutch packs) and, I suspect, it uses some straight cut gears which because of the required clearances make more slapping noises than the normal helical cut gears which are normally used in the grocery getter differentials simply because they are quieter. The TC uses a Quaife all gear unit. The design is used in some of the worlds highest performing cars up to and including F1.

Of course this is only my opinion based on online references like the following;

all above sounds about normal with mine as well.


feel comforted by words like performance and F1 lol

If you lift the car, on the tranny there will be a drain plug low, and identical to it theres a fill plug up higher. Crack the fill plug and add the additive. just realized as im typing this its from like 2009 haha but if you still want to add some thing its right there

Normal on these cars, I was wondering as well when I bought the car. However a great mod to improve shifting drastically is the Powell Front Transmission Mount. No more wheel hop, shifter is more precise and everything feels more firm. You won't regret it and it's not expensive (110$)

tuned08ss

Noob question, which one is the front and which is the rear trans mount?

Gimpster

Holy old thread! I even posted in this in 2009....

But the front mount is the one on the RIGHT.

See if we can get this old thread going again.
Even though many said the tranny clunk is normal, I don't think it is. I have a 2009 SS with 244,000 Kms that doesn't make any clunk sound at all. Just bought a 2010 SS with 108,000 Kms yesterday and it has a clunk when making a normal 1st to 2nd shift. Almost seems like something loose in the front end or a mount issue.
Any other experiences or advice on this topic ??
Thanks

Might as well change the fluid. Could be something else clunking too.

Almost impossible to diagnose online. Especially if you're disagreeing with the general consensus.

I've had 3 different SS/TC sedans and a coupe. The coupe and the current ride both have LSD and are both noisy/clunky. The other two sedans I had without LSD didn't make nearly as much noise.

Edit - Just to be clear, the F35 is loud and clunky. Period. I do believe though that the LSD does make additional noises.

cluelessk

1-2 it's almost never a smooth transition for me. It almost feels like it falls into gear as I release the clutch.

You do realize this thread is 8 years old? Pot meet kettle........


I figured you being the thread police would see that and be complaining right away.

Don't throw stones from a glass house bud.

SECRETARIAT

No offence intended or stones thrown at all. Just continued on with this old thread cuz it sounded very similar to my situation.
Had the car checked at newly taken over local transmission shop. They told me was something internal in tranny and would be $600 for R&R, $600 for bench time plus parts.
Went on to other trusted tranny shop that has been around for years, told me after test drive he didn't think it was transmission.
Then went to garage I usually deal with. As we suspected transmission was fine, he knew right away from the test drive. To make a short story long car needs new lower control arm, the whole bushing is sliding up & down in the control arm. So it bangs or "clunks" when an aggressive shift is made.
Thanks for any help.

Yep the rear cabs can tear causing it to move around.
