AUTOMATIC TRANSMISSION SYSTEM - SYSTEM DESCRIPTION

SYSTEM DESCRIPTION

The ECT (Electronic controlled automatic transmission) is an automatic transmission that electronically controls shift timing using the ECM. The ECM detects electrical signals that indicate engine and driving conditions, and controls the shift point, based on driver habits and road conditions. As a result, fuel efficiency and power transmission performance are improved.


Shift shock has been reduced by controlling the engine and transmission simultaneously.


In addition, the ECT has features such as follows:

Diagnostic function.
Fail-safe function when a malfunction occurs.
