A control system for an air outlet of an air conditioner in a vehicle includes a motor, a first clutch configured to control a horizontal vane of the air outlet, a second clutch configured to control a longitudinal vane of the air outlet, a third clutch configured to control an opening degree of a ventilation door of the air outlet, and an engaging element of the motor being connected to the motor, for engaging the clutches. The motor adjusts the horizontal vane of the air outlet when the engaging element is engaged with the first clutch, the motor adjusts the longitudinal vane of the air outlet when the engaging element is engaged with the second clutch, and the motor adjusts the opening degree of the ventilation door of the air outlet when the engaging element of the motor is engaged with the third clutch.

A hybrid module is configured for arrangement in a torque path upstream from a transmission and downstream from an internal combustion engine. The hybrid module includes a hybrid drive unit including an electric motor including a rotor. The hybrid module also includes a torque converter and a connector non-rotatably fixing the rotor to the torque converter. The connector includes a first section non-rotatably fixed to the rotor, a second section non-rotatably fixed to the torque converter and a retainer axially fixing the first section and the second section together in an intermeshing arrangement so the first section and the second section are non-rotatably fixed together.

A CVT clutch is provided. A fixed sheave of the CVT clutch is statically mounted on an end of the post. A movable sheave assembly is dynamically mounted on the post. The movable sheave includes a recess cavity that is defined by a movable sheave housing. A spider is statically mounted on the post within the recess cavity of the movable sheave assembly. At least one interchangeable ramp is positioned within the recess cavity so that at least one space is provided between the at least one interchangeable ramp and a sheave face of the movable sheave housing. An engagement member is positioned to engage an associated interchangeable ramp and the spider.
