same thing happened to me.. i bought a shifter off ebay... they gave the rubber washers or watevers... it was a b**ch to put on.. the shifter moved side to side because the bolt connecting the shiftlinkage to the shifter had a gap in between them because they never gave me the metal bearings to fill in the gap...so yeah all u have to do is tighten the nt n bolt till the shifter doesnt move while in gear...
