I just replaced my cable too. Make sure you get the right one. I ordered mine from the dealer and when I got home I found out they ordered me the Wrong one. I did get the Right one in a couple of days.
There is no adjustment, atleast from what I saw, when I was under there. Compare your 2 cables together, if your orig cable is not snapped. Your new cable might be shorter, not allowing it to travel the distance needed for the lower gear selections.
HTH,
