Mary M Cross Lanes , WV May 17, 2016 Appliance: General Electric Washer WPSR3120W0WW Ge Washer Wpsr3120w0ww: Washing machine transmission leaking oil. How to replace Hub Nut. Replaced transmission, all seals, and dampers. It is a complicated, messy repair but costs much less than replacing the machine. This is the second tranny I have put in the 30 year old machine and now it works like new. Take the time to replace all seals if you do this repair. No use putting a new tranny in with old seals that will crack. 5 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 2+ hours
