A diverter valve is placed between a source of cooling and/or lubricating fluid and the selected one of the fluid actuated clutches and operative to divert fluid therefrom in response to the transmission being placed in the selected gear ratio. A sensor arrangement is operative to sense the transmission gear ratio and deliver a signal to condition the diverter valve.
