Nissan automatic transmission power supply
*Nissan automatic transmission receives power from the battery through the automatic transmission relay.
* The automatic transmission relay is controlled by the engine control module (ECM).
* The ECM sends shift signals to the TCU, which then activates the appropriate shift solenoids.
Nissan automatic transmission control signal
* The gear selector position sensor sends a signal to the TCU indicating the selected gear selector position.
* The input and output shaft speed sensors send signals to the TCU, which are used to determine the current gear ratio and engine speed.
*The ATF temperature sensor sends a signal to the TCU, which is used to regulate transmission fluid temperature.
* The TCU receives all these signals and controls the shift solenoids accordingly to ensure smooth gear shifting.
Note: The location and type of electrical components may vary depending on your Nissan model. Always refer to the service manual for your specific model before performing any work on the automatic transmission’s electrical systems.
