Reasons why the “Automatic” gearbox indicator may light up:
Fluid levels:
*Low transmission fluid level
* Contaminated transmission fluid
Electrical problems:
* Faulty transmission speed sensor
* Poor contact of electrical connectors
*Wiring problems
Mechanical problems:
* Worn or damaged gearbox
* Torque converter problems
*Low transmission fluid pressure
Other problems:
* Faulty gear selector position sensor
* Clutch slipping
What to do if the “Automatic” gearbox indicator lights up:
1. Check the fluid level. Check the transmission dipstick with the engine running and the selector engaged in park mode. The fluid level should be between the “Min” and “Max” marks.
2. Scan trouble codes. Connect a diagnostic scanner to your vehicle to read trouble codes that may indicate the specific cause of the problem.
3. Contact a mechanic. If you are not sure why the light is on, seek professional help. The mechanic will conduct a diagnosis, determine the cause and offer a solution.
Consequences of ignoring the “Automatic” gearbox indicator:
* Further damage to the gearbox
* Increased fuel consumption
*Difficulty shifting gears
*Loss of power or slipping
*In extreme cases, the transmission may fail completely
