Gear selector assembly construction
The housing, shiftlock solenoid (1) and mounting lever for the ignition switch interlock cable are common to both gear selector assemblies.
In the 4T65EV / EV-GT the solenoid in the gear selector assembly has a reverse inhibitor function. The reverse inhibitor makes it impossible to engage R and P when the car is traveling faster than 12 km/h (8 mph). The gear selector assembly (and therefore the solenoid) is supplied with current and signals via the connector on the rear side.
A printed circuit board (2) is located under the top panel (3). On the circuit board are the "Winter" button (8) and 14 LEDs (13 LEDs with Geartronic) which light up the gear position (4) The LEDs also indicate the selected gear.
