My 2016 Corvette is a bit over 4 years old and I was thinking that the clutch fluid should be replaced, especially since these have slave cylinders with seals that let crap into the fluid. Like most owners I have been doing the "Ranger Method" to replace the fluid in the reservoir then pump the clutch, then repeat several times. But that doesn't really get all the gunk out of the lower part of the system. So a simple flush shouldn't be a big deal, right? LOL. Have a look at this. Some folks go on to install remote speed bleeders on theirs but doing that requires that the clutch be dropped! I won't post the procedure for that.
