Default camaro ss noisy transmission

Just bought a camaro as i went for the test drive there was no noise like this. Original owner said it was the original clutch. I havent driven manual in a while. Now as im releasing the clutch i hear a noise very hard to explain but it sounds like something is rattling or as i take off in first. If i rev it up to about 1500 rpm it goes away either i dont hear it anymore or it just goes away. We lifted the car today and heard it coming from the transmission. The mechanic said were gonna have to drop the transmission and check it out and maybe rebuild it. Do you think the clutch is gone? Is it a t-56 in there? Im scared now this is gonna cost me more money. HELPPPPPPPP I hope its just a clutch (maybe i can video tape it and post it)

See if you can get a vid of the sound posted. Yes, you have a T-56 transmission.

Benign rattles in T56's are quite common. You just want to be sure you don't have a more serious rattle (input shaft bearing going, etc.). The fact that the noise goes away at 1500 rpm (as load is applied) is more indicative of neutral gear rollover noise....a common issue with the T56's. You'll hear this rattle with the clutch pedal up in neutral with rpms at idle to approx 1500. It will go away with the pedal depressed (input shaft now disconnected). On some (or most) cars that rattle goes away once under load and the gears engage. There are also some benign noises from the shifter handle that will be present at all rpms (some cars). I wouldn't go on one mechanic's word to drop that transmission. You might end up find nothing. If you have a built engine with a built clutch/transmission the chances of getting rattles and noises seems to increase. If you're new to this car you might be picking up on rattles as you get used to driving it. Sometimes we don't always hear those when test driving the car the first 1 or 2 times. If you test drove the car with windows down, or radio on, etc. there's a good chance you won't hear any of the possible trans or undercarriage rattles and whines.

How many miles on that transmission? Ensure you're dealing with a reputable manual transmission specialist. Dropping the transmission is not the first answer unless you can do it yourself or with friends where it won't cost much. There's almost always noises of some sort coming from the transmission area...and they aren't always from the transmission internals. If at some point you have no alternative but to drop the trans you should have a game plan to replace the clutch, slaves, and rework the trans as required. You want to do all that only once....the right way, especially on a high mileage drive train. There's lots of info on this site with respect to transmission noises and what items to replace/rebuild if the time comes.

If it's the original clutch how many miles does the car have on it, what yr is the car..?
When my pilot bearing went out, it also made a odd rattling noise from a take off, then it was quiet.
As already stated, post a video clip if possible.

ill need to get a video for this. it is the original clutch and it has 87000 miles on it no engine mods or transmission mods. I'm sure the noise will get louder but the car is still drivable. it doesnt make noise when the car is in neutral or when the clutch is pressed.

Most likely the throw out bearing on the end of the slave. When you push the clutch down and the throw out bearing touches the pressure plate the noise goes away because it now has pressure on it pushing against the slave

Negotiate the price as if the car needed a new clutch is my advice

When you say "releasing the clutch" do you mean the pedal rising (clutch engaging) or pedal pushed down (clutch dis-engaging)?

A failing throw out bearing normally makes noise as you depress the clutch pedal. Once coming off the pedal and adding rpms a T/O bearing noise should go away as it's no longer doing work. And if it's a T/O bearing it should happen in other gears as you disengage the clutch...not just first gear.

I'm still don't know exactly what the problem is but that's NOT a normal sound. Regardless, what the actual problem is with in the trans you need to drop the trans so you can find and fix the problem.
