How to replace bushings of loose gear shifter of Mercedes?

Console shifter or column shifter? Are the worn bushings on the transmission or the shifter? The bushings can usually be bought at Autozone or similar stores.
Column shifters are secured to the column with a split pin through the center that needs to be driven out to change the bushing. Floor shifters need the console to be removed; usually 4-6 screws or pins accomplishes this. Shifters can be secured to linkage with pins or nuts and bolts.

There will usually be one at the very back of the console and 2 or 3 on either side.

My pleasure.
