Description And Operation: Overview

WARNING: This page is about a different car, the 2018 Jaguar XE and 2017 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.

The external controls for the automatic transmission comprise a Transmission Control Switch (TCS), two paddle switches and an Emergency Park Release (EPR) assembly.

The rotary TCS transmits driver transmission selections to the Transmission Control Module (TCM) on the High Speed (HS) Controller Area Network (CAN) Powertrain systems bus. The steering wheel mounted paddle switches can be used to initiate gear changes, with the TCS in either the 'D' (Drive) or 'S' (Sport) position, causing a change of operating mode from automatic gear selection to manual gear selection.

The Emergency Park Release (EPR) is used to put the transmission in Neutral ('N') during vehicle recovery operations, when it is not possible to put the transmission in neutral ('N') using the TCS.
