Warning lights

Transmission temperature light

The automatic transmission fluid is overheating.

Urgency:Stop driving

Is it safe to keep driving?

No. Pull over and let it cool with the engine idling in Park. Overheated fluid breaks down and destroys the transmission.

Likely causes

  • Towing or heavy load in hot weather
  • Low or degraded transmission fluid
  • Blocked transmission cooler
  • Internal transmission fault

Typical repair cost (US)

$150 – $4,000

A fluid service at the low end; a transmission rebuild at the high end.

A typical range, not a quote. Actual cost depends on the car, the shop and the fault.

What to do now

  1. Stop and let the transmission cool before continuing.
  2. Check fluid level and condition if your car has a dipstick; dark or burnt-smelling fluid needs changing.
  3. If it recurs without a heavy load, have the transmission inspected.
