Shift cable

This is a picture of the new cable end that goes into the transmission. Note: the adjusting wheel assembly isn't there. The old cable assy has an adjusting wheel assy attached. How is the old adjusting wheel assy removed from the old cable?
Sorry about fuzy pic.

If it doesn't rotate than treat it like a rusted bolt/ nut and soak it with your deruster/ lubricant of choice
