Re: C&C 30 MK1 Shifter help.
I think you have an Atomic-4 with an old Teleflex cable.
Why don't you try lubricating it before replacing it? Remove the cable, and hang it in your garage. Apply ATF fluid to the inner, moving part and let it run down into the casing for about 30 minutes. Then, try to operate the cable and work the ATF around.
