Yes. My indy guy ordered the parts for me and is doing the install. If you go to a dealer they will tell you the same thing, the software states they are supposed to replace all 3 parts.Still waiting for tow. Anywho you got the new Porsche cables/ kit that's about 750 bucks?
You can find it on suncoast (its listed only under the 987.2 Cayman page but not the Boxster page for some reason. EDIT: Looks like its listed under boxster transmission page now too.) It's 3 parts:
Shift link piece
Shift cable support piece
My battery was also about to die, so with battery + part and labor for the shifter cable parts, it came out to $1844 total.
