SYSTEM DESCRIPTION
(a) The Electronic Controlled Automatic Transaxle (ECT) is an automatic transaxle that electronically controls shift timing using the ECM. The ECM detects electrical signals that indicate engine and driving conditions, and controls shift points based on driver habits and road conditions.
Shift shock is reduced by controlling the engine and transaxle simultaneously.
In addition, the ECT has the following features:
- Diagnostic function.
- Fail-safe function when a malfunction occurs.
