Urgency: High
Transmission Temperature Light
Have this checked promptly. It is not an immediate stop, but do not ignore it for long.
What the Transmission Temperature Light Means
The transmission temperature light on a your car warns the gearbox fluid is overheating. Hot fluid loses its protective properties fast, so this is a stop-and-cool situation to avoid serious transmission damage.
Common Causes
- Heavy towing or load
- Low transmission fluid level
- Old, degraded fluid
- Blocked transmission cooler
- Stuck thermostat or failing pump
How to Fix It
- Pull over safely and let the transmission cool with the engine idling in park
- Reduce load and avoid stop-start driving until cool
- Check transmission fluid level and condition
- Have the cooler and fluid inspected
- Service the fluid or repair the cooling circuit as diagnosed
