System description

  1. System description

  1. The electronic controlled automatic transaxle (ect) is an automatic transaxle 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 transaxle performance are improved.

    Shift shock is reduced by controlling the engine and transaxle simultaneously.

In addition, the ect has the following features:

How to proceed with troubleshooting

Hint:

  1. Vehicle brought to workshop

Shift solenoid "d" performance (shift solenoid valve s4)
System description The ecm uses signals from the output shaft speed sensor and input speed sensor to detect the actual gear position (1st, 2nd, 3rd or o/d gear). Then the ecm compares the actual gear with the shift schedule in the ecm memory to detect mechanical problems of the shift s ...
