To remove the trim plate,
1st remove the shifter T handle, small c-clip located to the front of the shifter (may have to slide the shifter skirt down to see it).
2nd remove the storage tray (small cubby that has the cig lighter in it) at the base of the shifter. It just pops out (work out one corner with a small flat bladed screw driver).
3rd lift out the shifter trim plate, 4 clips hold in place, start at one corner and work your way around releasing the clips.
