Product review (5 stars): Worked perfect for Kenmore 90 Series
Kept finding puddles of thick oil under my Kenmore washer. Thought I would need to replace the transmission (which would be grounds for replacement). Propped it up and looked underneath, found oil was only
Weaping where the transmission met the motor.
Replacement was straightforward, took me a while to punch out the old one with a flathead screwdriver and a hammer. I allowed the transmission to drain the rest of its oil through the input shaft seal hole overnight (use a drain pan!) Refilled the transmission with 80-90w gear oil from the auto store. I refilled through the same seal hole as I drained from, it took several applications as it fills slowly (try turning the input shaft if the oil is not draining into the holes.)
To install the new seal, I used a large socket and a hammer. I used the same tools to replace the coupling (cheap part, worth replacing). Reinstall the transmission, strap the motor/pump back on,  you're good to go. No more oil leakage and the wash cycle seems quieter.

P.s. I only used one of the seals, you'll see which one fits for your particular model just by size.
