The gear case (transmission) on my Kenmore Direct Drive Top Load Washer is labelled 389228.
What replacement do you have that can be used? It does not spin or agitate. It drains the water so the motor and motor coupler is good.
Do you have to remove the basket to change the transmission?
The model number for your unit is not coming up so we cannot look the parts up. This issue would most likely not be caused by the gearcase but would be more likely the motor coupler. Even though the drain pump runs and pumps out this would still most likely be the case as the drain pump sits on the outside of the motor and the motor coupler sits between the gearcase and the motor. If this is broken it will not agitate or spin.
