Product review (5 stars): it saved my transmission
Just what I needed- I used the larger seal- my washer is an 04 kenmore.  I thought the top seal would be the bad one- but it was this side one- at the motor drive.  Had to dig the old one out with screwdriver.  And had to use sealer ( not the tightest fit.)  It is probably a little better than the orig equipment.  I had oil sprayed on the inside of the cabinet and the floor.
