Likely your shifter bushings are like mine were. There is a cup on the bottom of the shifter itself, and this bushing and then the coupler. Unless you have replaced them before, get a full set of shifer bushings and take a look at the coupler before you order. If the plastic parts in the coupler are shot decide the budget, replace the plastic parts, or replace the coupler with a new one, or a upgraded one. Once you know the bushings are fresh and right, then get the coupler adjusted.
