If your C6 3 speed is correctly filed with fluid and it
still slips, there is pretty much nothing you can do. It
does however have an adjustable intermediate band if the
slippage is in second gear. It is externall adjustable. If
you do not know what you are doing, have it checked. Other
than that here is not much to be done less than an overhaul.
The longer you drive it slipping if this is the problem, the
less chance you have that the problem can be helped.
