Product review (1 stars): Worked fine for a few weeks. UPDATED REVIEW 3/22/12
Like others, Youtube helped me diagnose and repair my washer, which is over 10 yrs old.  I considered the upgraded version with the metal insert, but decided I'd stick with the original.  I don't think the washer will last long enough to wear this part out again. One tip: I was having a little trouble connecting the motor side to the transmission side, pushing the cream-colored prongs into the rubber bushing.  So I sprayed a little soapy water into the holes in the bushing.  This acted as a lubricant and dried harmlessly.  Also, if you've never replaced the lid switch, might be worth spending $4-$5 and replacing it too while you have the body of the washer off. Shipping was by USMail, no tracking available, and took several days.

Updated. OK, it's a few weeks later and this coupler broke, on a Friday. I got one at the local Sears Parts counter (in stock today), the updated 285753A with metal insert, for $19.81. Fit better than this one, easier to push the prongs into the rubber bushing.
