When you install a new cable you set it up so that when you pull the cable out approximately 1 cm. and let it snap back you can hear the little wheel that it rides on snap against it's stop in the transmission. With it adjusted like this you tighten it down, recheck it, and then slide the little rubber dealy over the end of the cable sheath up by the throttle bobbin and then carefully crimp the sleeve onto the cable. Sometimes you will run into one where a knuckle head has either set the cable up wrong to start with and then crimped the sleeve or set it up right and then crimped the sleeve without putting the rubber in its place. Either way you end up with a mal adjusted cable/sleeve. If it is too tight it will shift late, if it is too loose you will shift too soon. I run into these often enought that I still stock the sleeve for the cable. I have never purchased these on the outside, I always order them through Volvo. If yours is in fact mal adjusted then order one up, CAREFULLY, cut the old one off, adjust the cable correctly, makes sure that the little rubber is in place on the end of the sheat, and then install your cable sleeve and be done with it.
