It does not twist off. You have to wiggle it back and forth and pull up on it. It takes some work, but will pull off.

shifter
NO it will not.
Been a while, but don't you Take the boot off inside to get to the shifter. It either has a locking ring that holds the shifter in or 4 bolts holding the shifter in. In either case, remove it and the shifter pulls out.

It does not have one. It has a 4x4 Actuator in the front housing.
