OVERVIEW
The external controls for the transmission consist of a JaguarDrive selector, two paddle switches and an emergency park release.
The JaguarDrive selector transmits driver transmission selections to the transmission control module (TCM). The paddle switches can be used to initiate gear changes, with the JaguarDrive selector in either the D or S position, causing a change of operating mode from automatic gear selection to manual gear selection. The emergency park release ensures the transmission is kept in neutral during vehicle recovery operations.
Four additional switches adjacent to the JaguarDrive selector control the JaguarDrive control functions. Refer to: Ride and Handling Optimization (204-06, Description and Operation).
