Didn't do enough research on Youtube and ordered a new clutch. Also ordered a drive coupling since mine was looking a bit beat up. I installed them and it didn't fix the situation. I was afraid it might be a transmission issue, but I did a lot more Youtube video watching and through some newly learned step by step trouble shooting steps I learned that the problem was the wash tub drive block. I ordered it and the special spanner wrench (you need that silly tool, I tried a hammer and screwdriver with no results). The nut came right off with the spanner. I had to wiggle the tub back and forth quite a bit to loosen it up. Eventually it slid right off the drive block. I replaced the old drive block with the new one tapping into place with a hammer & a piece of wood. I put the washer all back together and it's up and running fine. If I was to do it over again, I would have spent more time researching up front and then I would have known how easily the cabinet comes off and the washer comes apart (first time I did it, I removed the back panel and everything attached to it). I also would have known to go through all the trouble shooting steps (like testing the clutch) to find out what the real issue was. On a side note be careful not to drop tools into the tub, it will chip the enamel. In closing I'm glad I stuck with it and repaired it, instead of scraping it and buying a new one. The old washers are way better quality than the new ones and in the long run it only cost $100 to fix it vs. $500-$600 for a new one. Hopefully it will run for another 20 years :)
