ABSTRACT:
An improved switch system is incorporated into a multi-speed transmission and engine combination. The switch system provides a positive electronic signal to an electronic control unit for the engine of both when the transmission is in a neutral state and when the transmission is in a gear-engaged state. In one embodiment, a switch plunger rides within a switch housing between two extreme positions. The switch plunger is at one axial position when the transmission is in neutral, and at the other axial position when the transmission is in a gear-engaged state. At either position, an electric circuit is completed and a signal is sent to an electronic control unit. The electronic control unit is thus provided with positive position feedback for the transmission. The electronic control unit will preferably also have the ability to control the engine speed to synchronize the engine speed with a desired engine speed for the next selected gear ratio to achieve synchronization between the speeds when the shift if completed. The electronic control unit does not begin to modify the engine speed until it has received a positive signal that the transmission is in neutral.
