A transmission includes provisions to mount two accessory drive units and to transmit power to the accessory drive units from an engine. The accessories are driven by an accessory drive gear that is coupled to a torque converter impeller as opposed to a turbine such that power is provided to the accessories regardless of the selected gear state or vehicle speed. The accessory drive gear also transmits power to an off-axis transmission pump. In one embodiment, power is transferred to the accessories via idler gears that is supported by the transmission housing and is present even when no accessory is installed. In another embodiment, the idler gear is supported by the accessory drive unit and is only present when the accessory is installed.
