AUTOMATIC TRANSMISSION ELECTRONIC CONTROL SYSTEM STRUCTURAL VIEW

BHE051301026T04

## Outline

Features

• A stand-alone TCM, used exclusively for transmission control, performs various controls such as up and down-shifts, according to signals relayed from sensors and switches.

• Direct electronic shift control provides superior shift quality.

• A superior balance has been achieved between the quick shift response of a sports car and the mild shift quality of a luxury car.

• In particular, the response when downshifting in manual mode has been greatly heightened, resulting in a highly responsive and direct shift feeling.
