Product review (5 stars): Agitation was fine, but clothes were soaking wet
Watched several online videos and tried a few thing including cleaning the inlet filters for the water hookup but that did not help.  The washing machine a 10+ year old Whirlpool top load Cabrio would not spin.  Agitation was fine, but clothes were soaking wet.  Ordered this and replaced it in about 20 minutes and now it works like a charm.  The Whirlpool model number is WTW5640XW0 in case others are having the same issue.
