Abstract:
One implementation of a six-speed transmission includes a first gearset including first and second planetary gearsets each having a number of teeth. The transmission also has a second gearset including a third planetary gearset operably associated with the first and second planetary gearsets. The third planetary gearset has an equal number of teeth with respect to one of the first and second planetary gearsets. The transmission also has a first plurality of shift elements operably associated with the first and second planetary gearsets, each of the first plurality of shift elements being movable between a released state and an applied state to selectively engage at least one of the first and second planetary gearsets. The transmission also has a second plurality of shift elements operably associated with the third planetary gearset, each of the second plurality of shift elements being movable between a released state and an applied state to selectively engage the third planetary gearset. The transmission also has a controller operably associated with the first plurality of shift elements and the second plurality of shift elements to selectively engage the first, second and third planetary gearsets.
