New Clutch??
Hi, new here. First post. I did some searching already. Maybe i missed it. I have a 2000 c5. But i made the mistake apparently of going to a shop and had a new clutch put in. They did not replace the throwout bearing. Just installed a new napa clutch kit and that was all. Now my car makes a whirring noise that sounds like it is coming from under the shifter. My clutch pedal also doesnt engage til it is about halfway pressed but once it is there it engages no problem. Anyways, im wondering if anyone has any advice on what the problem could be because the shop insists the sound is normal even though it wasnt there before. Thanks for reading.

I don't know of too many shops that would not replace the throw out bearing when replacing the clutch. Unfortunately the only way to diagnose the whirling noise is to take everting apart, I would find a different shop to do the work.

Alright thanks. Also i saw others would replace the slave cylinder when doing a clutch. Not sure how necessary that is. And they add a remote bleeder. But i will go to a different shop and see what they say. Huge mistake. I want the shop i went to to fix it because it is under their warranty. But im sick of dealing with them. They dont know what they are doing. And they don't want to do 10 hours of labor again for free. If i go to another shop ill have to pay again.

WOW! Anytime clutch work is accomplished, the Clutch disc, Pressure Plate, Slave Cylinder and the THROWOUT BEARING and Pilot bearing should all be replaced. Depending on the condition of the flywheel, it may need replaced also or at a minimum, resurfaced.
As much clutch dust that gets into the Clutch hydraulic system, the Master cyl should also be replaced.
Your shop is WRONG. Noises in the bell housing are NOT normal. That said however, If you put the transmission in Neutral and let out the clutch, you will hear a normal faint drive train clicking noise that happens because of stack up tolerances between all the splined parts in the clutch,/ input shaft transmission ect.. Depressing the clutch, will make that clicking stop. Not a whirring noise!! That is NOT NORMAL! If you depress the clutch, does it change the noise?
Like mmartinez stated, "It ALL has to come back apart to replace that bearing. Where do you live. Someone close may be able to reach out and help diagnose it.

How many miles do you have on the car?
Why did you replace the clutch??
Have you ever checked the master cyl fluid level or condition? Bet ya its black thick and nasty. Should be clear and thin.
Have you ever changed out the clutch master cylinder fluid? Suck it out and put in new. Take the cap bladder off the cap and get the water out of it.
This most likely wont make the noise any better but it may help with the engagement issues. The system should be bled and fresh fluid put in. You will most likely have to do a fluid change 5-6 times before it gets anywhere near clean after a day or two of using it.

I have not checked the fluid. They didnt say they did either. I will have to ask. Had the oil changed though. After the work they did im not even comfortable thinking about them even test driving my car. They were more concenred with am i flipping the car or keeping it. I'm like idk i just got the damn thing. My other replies where i responded to the both of you are pending moderator approval because i used the quote feature apparently. Not sure how long that will take. Or why it's doing that. Cause if i just post in the thread lik so it works fine.
