I grabbed the base of the old agitator with two hands placed 180 degrees apart and pulled straight up with force. The agitator came right out. Be careful not to hit you face with the agitator when removing it. I then took the new agitator and lined the splines up with the splines on the coupler and pressed straight down until agitator clicked on. Repair done. Washer fixed. Agitates like new again.
