When I took it apart it looked like the agitator and coupler were both worn and since they're both plastic (or at least not metal) I decided to replace them both at once to be sure the issue was fixed. Runs like new now and for less then $50.00 including shipping and less than an hour of my time. The only tricky part was removing the agitator. When the cap was removed there was no nut holding the agitator on. AppliancePartsPro sent me a PDF copy of the where I learned you just needed to get your fingers under opposite edges and pull up forcefully. I did put a folded bath towel on top of the agitator to avoid smacking myself in the face when it came free. Of the hour the actual fix took less than 10 minutes, the rest was diagnosis and finding out how to get it apart.
