2015 combo sloppy gear selector

[Keith1000]

I have a 2015 Vauxhall combo with sloppy gearbox selector. I don’t think this is an F23 box but cannot find any solution to replacing the bush. Any help please ?

Have the same issue with a Nissan Juke and was thinking of using a silicon to pack out the wear in the plastic bush - nothing to lose if it stiffens it up - got to be replaced anyway I guess
