A washing machine transmission is disclosed for alternately producing either oscillating agitator drive or basket spin upon rotation of the drive motor in reverse directions. The transmission includes an input shaft rotated by the drive motor and extending parallel to a concentric spin tube and agitator drive shaft. An agitator drive element is oscillated by an oscillation mechanism and in a first direction of rotation of the input shaft is connected to an agitator drive shaft to oscillate the agitator, while in the reverse direction a spin input gear is clutched to the input shaft and drives a spin gear drivingly connected to the spin tube for rotating the basket. A spring-applied friction brake acts on the spin gear to brake the spin tube, but is released upon rotation of the spin tube for spinning the basket by mating cam surfaces acting between the spin gear and the tube to axially retract the spin gear and release the brake. A spin neutral is achieved by a solenoid-operated shifter delaying clutching action between the spin input gear and the input shaft, allowing pump-down of the water prior to initiation of the basket spin.
