Couldn't get a repairman to come out so decided to do the work myself. I have a large capacity, a heavy-duty machine with a porcelain wash tub, and I didn't want to replace it with a lesser unit.
Not knowing what part was causing the problem, I started with the least expensive components and was then able to conclude it was the transmission.
In all, I replaced 5 components that were either worn (after 39 years!), or were leaking water due to worn seals.
Without the videos, I wouldn't have tackled the project. Seeing the videos I saw that the required work was easy to do.
For much less than half the price of a new machine I had my Washer back in service, and running like a new machine.
