Default clutch on ls7

Purchased 2013 with 9,000 miles . appeared pampered. Just reached 12,000 . Clutch slippage under moderate to hard acceleration. Seems a bit premature for trouble. Anybody knows of similar issues , adjustments , simple troubleshooting . I live in Hickory NC . Any good , honest shops to recommend ?

The clutch in that car (if stock) is a LUK. Exactly the same clutch as used on the LS3. Seems like the previous owner was either hard on the clutch or didn't know how to properly use one or the self adjusting mechanism failed. Before you spend any money try pumping the clutch completely to the floor several times with the engine running at about 3000 rpm and see if it still slips after that. If it has been slipping for a while it may be burnt up. See link below.

They will also slip after a couple hard runs. If it does it every time then yes it's probably toast. I ran mid elevens with stock clutch and almost 50k miles but would have to let it cool after a couple hard passes...

Slipping right after the higher RPM shift, or in gear, clutch out for a few second, then getting on it?

If the later, then time for a new clutch.

If the former, time to do a ranger fluid flush on the clutch fluid system.
