I just had the same problem. If you set the washer on it's back you will see the drive motor transmission coupler item #1195967.
It it is the coupler you will see right away that it is broken.
You'll have to take off the motor to replace it.
It is relatively simple. Make sure prior to putting it in you let it soak in hot water for at least 10 - 15 minutes. If you don't it will crack.Also make sure you watch the capacity of you loads.
