Its not the drive coupling. I did replace it last year so that was my first thing to check. When I noticed it was not draining I had actually forgotten about the coupling, so I depressed the lid switch and grabbed the tub and spun it a couple time and it actually began to spin. So after a little research and disassembly I now know there is a clutch assembly but there looks to be two similar looking parts, one is on the trans and one is on the bottom of the tub. Heres the question, which one is the clutch and how can I tell if it is slipping. And could it be anything else. When I turn the drive on the trans it turns that portion that is connected to it and it does not slip, at least not in my hand. Thanks in advance.
