Stuart B Grand Rapids , MI May 25, 2019 Appliance: Kenmore Washer 11026902690 Kenmore Washer 11026902690: Washer would agitate but not spin. How to replace Washer Centerpost Gasket. After checking coupler, clutch and other parts, I rebuilt the transmission using neutral assembly pack. The repair is straightforward but messy since the transmission is full of gear oil (I used new 80-90w oil after cleaning out the transmission with solvent). Don't forget blue silicone for the transmission case to prevent oil from leaking. 2 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 2+ hours
