The speed sensor is responsible for transmitting important information to the automatic transmission electronic control unit about the speed of rotation of the gearbox output shaft. This data is used for:
* Determines the current driving mode (acceleration, deceleration, constant speed)
* Calculate the optimal gear shift point
* Torque converter lock-up adjustments
* Kick-down mode control
* Diagnosis of faults in the gearbox
Accurate information about the speed of rotation of the automatic transmission output shaft is necessary to ensure smooth and efficient gear shifting, preventing slipping and wear of transmission components.
