Description

The automatic transmission control system relies on various measurement data to determine the current control status and extrapolate the required compensation values. These values are used to control the actuators and achieve the desired control result. If a transmission problem, including the gearbox, has been identified, perform transmission self-diagnosis and basic inspection (check oil and fluid level), then check the control of system components using the diagnostic tool.
