E-Shift: features, advantages & disadvantages

E-Shift is a name of a manual shifting system for automatic transmissions installed on Jeep and Lexus cars. The gearbox is controlled electronically. On Jeep cars, this system appeared in 2014 when the Grand Cherokee with 8-speed automatic transmission debuted. On Lexus cars it started to be used quite earlier: in 1999 on the IS saloon.

Features

The main distinctive feature of the E-Shift system on Jeeps is the design of the gear selector which allows the driver to choose the driving mode and to shift in manual mode. The lever returns to its initial position after each movement. The lever features built-in LED lights, which inform about the current transmission mode.

On Lexus cars, the E-Shift lever has a more conventional design. It stays in a selected position until the driver changes mode. Moreover, paddle shifters can be used for shifting in manual mode.
