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 is reduced by controlling the engine and transmission simultaneously.

In addition, the ECT has the following features:

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