What does it mean when your transmission warning light comes on?
When your vehicle's transmission warning light comes on, it indicates a potential issue with your car's transmission system. This light is designed to alert you to a problem that requires immediate attention to prevent further damage or costly repairs. Understanding what the transmission warning light means and how to respond can help you maintain the health of your vehicle's transmission.
What the Transmission Warning Light Signifies
The transmission warning light, also known as the "check transmission" or "service transmission" light, is part of your vehicle's onboard diagnostics system. It is triggered when the system detects a problem with the transmission. This could be due to a variety of issues, including:
- Low transmission fluid level or quality
- Transmission fluid leak
- Transmission sensor or solenoid failure
- Transmission gear or component wear or damage
- Transmission control module (TCM) malfunction
When the transmission warning light illuminates, it's important to take action promptly to identify and address the underlying problem.
How to Respond to a Transmission Warning Light
If your transmission warning light comes on, here are the steps you should take:
- Check the transmission fluid level: Safely pull over and check the transmission fluid level according to your owner's manual. Top up the fluid if it's low, but be cautious of overfilling.
- Inspect for leaks: Look for any signs of transmission fluid leaks, such as puddles under the vehicle or fluid dripping from the transmission.
- Scan for diagnostic codes: Use an OBD-II scanner or take your vehicle to a mechanic to read any diagnostic trouble codes stored in the vehicle's computer. These codes can provide valuable information about the specific issue.
- Seek professional diagnosis and repair: If the transmission fluid is low or there are signs of a leak, or if the diagnostic codes indicate a more serious problem, take your vehicle to a qualified mechanic for further inspection and repair.
Ignoring a transmission warning light can lead to further damage and more costly repairs, so it's important to address the issue as soon as possible. By taking prompt action, you can help maintain the health and longevity of your vehicle's transmission.
What would cause the transmission light to come on?
It's a signal that something could be wrong with your vehicle's transmission system, like low fluid, overheating, or even worn components. Ignoring it can lead to costly repairs down the road. If that light pops up, it's time to get your vehicle checked! Stay safe and keep your car running smoothly.
What are symptoms of low transmission fluid?
If your gears are slipping, it's a clear sign your car's running low on transmission fluid. When experiencing sudden up and down shifts, high RPMs right before shifting, or erratic shifting, seek assistance from your local service center to prevent your transmission from overheating or becoming damaged.
Can you drive with a transmission fault?
Driving with Transmission Fault
If you suspect a serious problem, it is always best to stop driving and seek professional assistance. Regular maintenance and responsible driving can help prevent transmission faults, saving you time, money, and potential headaches in the long run.
Will transmission light come on if fluid is low?
Common Causes of Transmission Issues
When your transmission temperature warning light or automatic transmission warning light comes on, it often points to a low transmission fluid level, which restricts transmission fluid flow and impacts system performance.
How much does it cost to fix transmission problems?
Average transmission repair costs range from $300 to $1,400. For example, if your manual transmission needs a new clutch, you can reasonably expect to pay around $800 to $1,500. On the other hand, transmission replacement is one of the most expensive repairs you can get. Replacements can range from $1,800 to $3,400.

How do you fix a transmission fault?
How Do You Fix a Transmission Failure? Some transmission issues can be fixed with a simple in-vehicle repair or software update. But if the transmission has failed internally, it will either need to be rebuilt (if possible) or replaced. Many dealerships and full-service repair shops no longer rebuilt transmissions.
Can I still drive with the transmission light on?
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.
Can you just add transmission fluid?
Insert long funnel into automatic transmission fluid dipstick hole. Carefully add automatic transmission fluid in small increments and recheck level each time until fluid level reaches "warm" line. CAUTION: DO NOT OVERFILL OR SPILL AUTOMATIC TRANSMISSION FLUID ON HOT ENGINE PARTS!
Can low oil cause transmission light to come on?
Your transmission temperature warning light may come on for several reasons, including low fluid levels, overheating, or internal mechanical issues.
