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

On the your car, this red light means automatic transmission fluid temperature has climbed too high — often from towing, heavy loads, or low/old fluid. Continuing risks expensive gearbox harm.

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

  1. Pull over safely and let the transmission cool with the engine idling in park
  2. Reduce load and avoid stop-start driving until cool
  3. Check transmission fluid level and condition
  4. Have the cooler and fluid inspected
  5. Service the fluid or repair the cooling circuit as diagnosed
