Ok, before I knew this awesome site existed, I went to work replacing the motor coupling at the front of the washer (which I now know that's where it is). I began removing three large bolts and the (now I know) transmission AND motor came down to the floor. Now, when I try to put the motor and transmission back in place, it acts as though there is something in the way where the shaft goes up into the washtub. I sure hope this makes sense to someone! Any help is greatly appreciated.
