摘要:
A transmission includes an input shaft, an output shaft, a first plurality of gears, a second plurality of gears, and a series of engagement elements operable between an engaged position and a disengaged position. A controller is further provided to selectively toggle the series of engagement elements between the engaged position and the disengaged position to selectively couple one of the first plurality of gears or one of the second plurality of gears to the input shaft and the output shaft. The series of engagement elements sequentially couples the first plurality of gears to the input shaft and the output shaft during operation of the transmission and selectively couples one of the first plurality of gears or the second plurality of gears to the input shaft and the output shaft during a downshift operation of the transmission.
