2005 c6 manual trans
I just bought a 2005 c6. It has 122k miles on it and it runs great except when taking off. Does not matter what gear I'm in but the car makes a grinding noise... it will grind for a couple seconds then it goes away. Can anyone help me out with what it might be? And also maybe a solution.. thx chris

I would get under the car and look for anything suspicious while changing trans, diff and motor oil to look for shavings or contamination. Also the clutch info on a manual trans.

Check the torque on the rear axle nuts too. If they are still the original nuts they may be loose, the nuts were changed/upgraded around '08 or so. You can get them from your Chevy dealer for a couple bucks each.

Sounds like a throwout bearing or maybe a pilot bearing.. When my pilot bearing went bad it would make a grinding/squealing sound for a few seconds everytime I let the clutch out while in gear...WW

before i even get under the car i would open up the clutch resorvoir and check to see how much Dot 4 fluid is in there and how dirty it looks, if it's low it may cause the symptoms you are decribing.

I have changed mine a bunch with dot 4.. And mine is still doing it. My clutch spring did pop off the pedal.

... made quite a difference!(BTW: Amazon has a large syringe that can empty the clutch reservoir in one pull of the plunger. )

The clutch fluid being low or dirty may cause grinding getting the car in and out of gear, or while shifting gears.. I have never seen it cause grinding when it's in gear and the clutch is released like the OP is getting..It's not a bad idea to check your clutch fluid , but I don't think it's the problem..WW

Ranger method is a great idea I do it all the time but I don't think it's gonna fix this one based on what the OP is describing.
