I have an 88 vert with about 130,000 miles on her and I need help narrowing down a transmission noise before I take it to the shop. Here's what's happening. At low speeds (5-10 mph)with the clutch engaged I'm hearing a chirping sound coming from underneath the car. When I press the clutch pedal in it stops. If the I increase the speed to 15 to 20mph or decellerate from a high speed the chirping turns to more of a scraping sound. I am also getting a shutter in first and reverse. I installed a RP standard street clutch about 6 months ago. I have not noticed any lack in performance outside the noise and the shutter. Shifting is fine and I haven't noticed any clutch slippage.

This started about three months ago. About about two months ago I put redline transmission and differential oil in. The chirping stopped. Unitl yesterday. I think it's time for me to check this out more thoroughly but I would like to know where to start. Any help will be greatly appreciated.

Did you resurface the flywheel when you put in the new clutch?

is it a nasty gridning sound? well, not grindin just un pleasant? minght be a syncho, or a bearing within the drive assembly

Is it like a clicking sound? That's what i am getting after the clutch was replaced. I have narrowed it down to 2 reasons. 1) the throwout bearing. This is because on my 85-SE, i was getting this metallic grinding noise which would go away with the slight depressing of the clutch pedal. I simply adjusted the pedal by screwing in the rod between the pedal and master cylinder.
2) When I did a search on the forum, there were several people with similar problems and it seemed like the consensus opinion was a bad front or rear tranny bearing.
Strangely, from my experience and what i have read, it seems to happen after a clutch job or tranny removal.

It's not really a clicking. but at times it does sound like a gringing noise. And no I didn't resurface the fly wheel. Should I have?

hmm...this sounds like a tranny problem more than a clutch one.

One quick way to get some more 411 about things is to get under your car, remove the filler plugs and stick a finger inside (into the fluid.) If it smells like your mom - j/k! - er, if it smells burnt then you can be pretty sure that something in the tranny is hurting.

ttyl,

ya i got my car two days ago and i have smoke coming out of the shifter...i just think it needs tranny fluid...what do u guys think

I think it's time to **** a brick! That sounds baaaaaaaaad!

Check your fluid, too. If there's any in there. If it's either empty or the fluid's toasted (it will have a strong, unpleasant smell,) drain it and replace with Redline MT-90 (*not* MTL-90.) This is the best stuff you can get for your tranny. You'll need 3 quarts. And a suction gun, which can be found easily and is cheap.

Hope it's nothing too gross.

OK It's not the clutch or flywheel.

This could something simple, like an out of place heat shield..

Check the U-joints.
Like Rico05 says, a new chutch on a scorched flywheel can do that..
