The washing machine has made clunking sounds off and on for a while and wouldn't drain the water in some cases (clothes still wet). Not it seems the agitator will not spin at all. I can hear the motor turning when on the spin cycle but I am not able to move the agitator by hand at any point in the cycle.

I have seen where some of these models are known for having failing transmissions. I am wondering if there is a way to definitely test for transmission failure versus a thrust bearing or some other issue.

Thanks for your help.

Update at the bottom of this post.

In further troubleshooting I was able to freely pull the transmission pully from the bottom of the transmission without any tools (basically fell into my hand). I see some parts in the bottom of the casing that are loose (thrust bearing, e-clip etc.). The transmission, motor and "other" pully move freely by hand in both directions. The motor also moves in both directions under power - the motor was way too loose and able to move freely across its adjustment points by hand which is another issue.


Pulley that fell free and parts on the right I can see in the bottom housing of the pulley:

• Is the transmission supposed to move freely in both directions with light finger pressure (I can't think of a reason why not)?
  
• Are there any other "tests" I can perform before purchasing the pulley/bearing kit - want to make sure I still don't have a transmission issue since it is a known weak point in these washers.
  
• What parts should I replace in order to get the washer up and running (pulley, bearing kit, belt)? I am not looking to get out of this on the cheap and would like to replace anything needed all at once.

Thanks

UPDATE:
Replaced broken E clip. Agitator working now, but not getting any spin out of the tub. The agitator is working in 1/4 turns both directions throughout the wash, rinse and spin cycle. So, at this point it seems that the tub spinning is the only outstanding issue.
