Hey, i was looking at buying a 97 z28.....When i was driving it, and i gave it some gas at low rpms (noticed in third and fourth gear, most likely occurs in all gears), there was a strange noise, almost like a rattling.... Didnt sound particularly bad, and there was no change in ride or performance.... Anyway, i asked the guy, he said he's had that noise since he got the car, and it got worse when he put a new clutch in, and that it was just the throwout bearing vibrating under certain loads.... has anyone ever heard of a problem like this??

 

anyone have any ideas??

 

This is normal. I've had my 96 w/ 6 spd since new and it's always done it. The T56 has to be the noisiest transmission on earth.

A stock T56 can handle well over 500rwhp, and it is a bit of a noisy transmission. Just add headers, cam, exhaust etc.. and eventually you wont even notice the noise from the trans

 

this happens on my car if I let it get below about 1400 RPM in any gear except first...I think its load on the engine causing it to ping a bit, so I try to avoid it.

 

I would worry more if it didnt make the noise

 

i'd worry if it didn't make the noise too. my tranny had a little relieft from "the grind" when i did the pilot bearing/throwout bearing when i had the clutch done. still made the noise after the swap, though.

I'm not sure about the source of the noise you describe, but as you've heard these tranny's are noisey. I wanted to add that if you install a poly tranny mount (like I did) the the normal noise of the T56 will become more pronounced. Does this car have a poly tranny mount?

 

Could it be more pronounced on the M29 'Viper spec' T56's since they have hardened gears? . I would think the hardened metal would cause it to make more noise. Just a thought.
