I don't think it's the brakes--here's why...I got the agitator off, and while trying to break loose the big spanner nut (I don't have a spanner wrench) I grabbed the nut with a channel lock pliers and was able to spin the tub. I hear something dragging a bit, but I was able to spin it. I still can't get the shaft to spin. On my neighbors Whirlpool, I can grab the agitator (bottom 1/2) and spin it by hand. Mine is froze in place. Sounds like a trashed transmission, right?
