What does it mean when the automatic gearbox light is on?
When the automatic gearbox light on your vehicle's dashboard illuminates, it indicates a problem with the transmission or related components. This warning light is designed to alert you to potential issues that require immediate attention to prevent further damage or unsafe driving conditions.
Understanding the Automatic Gearbox Light
The automatic gearbox light, also known as the transmission warning light or check transmission light, is part of your vehicle's onboard diagnostics system. It is connected to various sensors and computers that monitor the performance and health of the transmission. When the system detects an issue, it triggers the warning light to illuminate on the dashboard.
The automatic gearbox light can indicate a wide range of problems, including:
- Low transmission fluid level or pressure
- Transmission fluid overheating
- Faulty transmission sensors or solenoids
- Transmission gear slippage or failure
- Electrical issues within the transmission control system
It's important to note that the specific cause of the warning light can vary depending on the make, model, and year of your vehicle. Some vehicles may have additional transmission-related warning lights, such as a "Service Transmission" or "Transmission Overheating" light, which provide more specific information about the issue.
What to Do When the Automatic Gearbox Light Is On
If the automatic gearbox light illuminates on your dashboard, it's crucial to take the following steps:
- Safely pull over and stop the vehicle: If the light is accompanied by unusual transmission behavior, such as slipping, jerking, or delayed gear changes, it's best to safely pull over and stop driving to avoid further damage.
- Check the transmission fluid level: Refer to your owner's manual for the proper procedure to check the transmission fluid level. If the fluid is low, add the recommended type and amount, then check the light again.
- Scan for diagnostic trouble codes: Use an OBD-II scanner or take your vehicle to a mechanic to read any diagnostic trouble codes stored in the transmission control module. These codes can provide valuable information about the specific issue causing the warning light.
- Schedule a professional inspection: Even if the light turns off after addressing the immediate issue, it's recommended to have a qualified mechanic inspect the transmission and related components to ensure there are no underlying problems that could lead to future failures.
Ignoring the automatic gearbox light can lead to further transmission damage and costly repairs. It's important to address the issue promptly to maintain the health and performance of your vehicle's transmission system.
What does the gearbox warning light mean?
Gear Shift Failure
The transmission system works with several other parts of the vehicle, including the gear shifter. If the gears start slipping or the vehicle shift interlock system isn't working, the transmission warning light will turn on.
What damages an automatic gearbox?

What would cause the transmission light to come on?
This light, often shaped like a gear with an exclamation mark, signals potential troubles such as low transmission fluid, electrical issues, faulty sensors, wiring issues, or clutch problems.
Can I drive with automatic gearbox warning?
We strongly advise against driving with the transmission warning light on, because it indicates there is a problem within the transmission system. Therefore, if you continue to drive, this could pose a safety risk, cause further damage, and leave you with a costly repair bill.
How to fix gearbox problems?
If there is a delay in the vehicle's transmission or it doesn't engage at all, there could either be a problem with fluid degradation or there could be a computer system problem. A gearbox fluid change should obviously solve the first issue, while the second may require a full reset of the vehicle's computer.
How much does it cost to fix an automatic gearbox?
A manual gearbox replacement can cost anywhere from £500 to upwards of £3,000. An automatic gearbox replacement can cost anywhere from £1,000 to upwards of £5,000. The availability of parts and any additional labour or installation fees can have an impact on the gearbox price.
Can you drive with gearbox fault?
Your gearbox - or transmission - is critical to the effective, safe functioning of your vehicle. Unlike a broken tail light, for example, a faulty gearbox could mean your car is put out of action, and may result in you being stranded by the roadside.
Can an automatic gearbox be fixed?
Yes, an automatic gearbox can be repaired. It's made up of a series of complex components, so when one component fails, it can affect the performance of the entire gearbox. 2. Don't wait until your gearbox fails completely before getting it repaired.
How long can I drive with the transmission light on?
You should stop driving as soon as safely possible once you see the light come on. Ongoing operation may exacerbate mechanical problems or wear. The longer you drive, the more likely major repairs or replacements become necessary down the road.
How do I know if my automatic gearbox is bad?
During gear changes, reluctance, slippage, or "trembling" are all warning signals that indicate a problem with an automatic gearbox. Grinding is more likely to occur with manuals. It is more probable that the engine and gearbox mounts will fail if the vehicle is making jerking and clunking noises.
