Abstract: A continuously variable transmission housing including an inner cover and an outer cover that define an interior chamber that is structured and operable to enclose a continuously variable transmission primary pulley, secondary pulley and pulley belt. The housing includes a duct panel mounted to the inner cover such that when the primary pulley is disposed within the interior chamber, the duct panel is disposed between an outer face of the primary pulley and the inner cover. An air duct is defined between the inner cover and the duct panel, wherein the air duct is fluidly connected to ambient air from an ambient environment external to the housing. The duct panel forms at least a portion of an ambient air inlet of the housing and includes a center opening that structured and operable to allow the ambient air to be drawn through the air duct and into the housing interior chamber.
