Can't remember its been so long since I've driven
What I did though (Don't laugh) was get that filler stuff for walls, jack my car up on the ramp, and squirt a TINY bit of that in gap, wait for it to dry slightly, then change through all the gears til its dry! worked a treat!!
STOP LAUGHING!!
I did have a bit of noise which I found out was that clip ring thing, which was touching the plate that sits on top, taped that up, and that was ok.... I love it though!
