ABSTRACT:
A control system for a vehicle transmission implements a method of controlling the transmission. The system includes a device for selecting the desired operating mode of the transmission, such as a gear shift lever, and a transmission sensor for sensing the actual operating mode of the transmission. A display is in communication with the device and the transmission sensor and displays both the desired operating mode and the actual operating mode of the transmission. A controller is in communication with the transmission and controls the operating mode of the transmission. An occupancy sensor, in communication with the controller, verifies that the driver is in the driver seat before the controller allows the transmission to be shifted out of a park mode.
