SYSTEM DESCRIPTION
1. SYSTEM DESCRIPTION
(a) The Electronic Controlled Automatic Transmission (ECT) is an automatic transmission that electronically
controls shift timing using the Engine Control Module (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 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.
