Won't shift into 3, 4,5, or 6

[Anker]

You must have a break in the cable.

Check where the 2 cables exit the outer sheath at the transmission. This part of the outer sheath should be securely attached to the transmission housing. The inner cables may be secure to the shift actuators but if the outer sheath is not the cables can't actually put enough pressure on the actuators.
