I am on my second shift cable in a year. After changing the shift cable the first time, the shifting was still a little harder then I would expect to be normal, but it did work and shift into gear properly. Now I am digging a little deeper to see if there is another cause for the hard shifting. I removed the detent spring and ball to check the condition. Spring looks normal, but the ball might have a little wear on it. With the detent spring and ball removed, moving the shift lever on side of transmission without cable is smooth and very easy. I haven't removed the outer detent sleeve yet to inspect that. I am not sure if there is enough clearance to remove with transmission installed. Hopefully there is. Could a worn sleeve cause hard shifting or am I looking in the wrong place?
