I opened a thread awhile back that I have no start in P but OK in N. Dealer called and told me it was due to a worn bushing and not the NSS. Can that be possible? They checked the NSS and it is in good condition. They also told me my front flex disc is in bad shape. What is the consequene of not having the flex disc fixed immediately?
