Yes keeping fluid clean helps but still will not correct the problem that has existed since the 1997 C5.
In many cases it happens when racing and fluid get too hot. Also induces the problem is ill designed long tube headers that is now close to the clutch fluid hose heating up the fluid.
Try covering that hose with heat shield wrapping.

The pity though is that all someone has to do is simply post on some forum and say "do this" and no one questions what they read and before you know it thousands of Corvettes are screwed up due to stupid mod ideas.
Getting the spring off is easier then putting it back on.

I tested this for several months and put the spring back in which showed the spring is there for a good reason and taking it off can cause worse shifting patterns.
