Transmission Temperature Light on a Aston Martin Vantage
Have this checked promptly. It is not an immediate stop, but do not ignore it for long.
What the Transmission Temperature Light Means on a Aston Martin Vantage
On the Aston Martin Vantage, 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.
How Urgent Is the Transmission Temperature Light?
How worried should you be? For the Transmission Temperature Light on a Aston Martin Vantage, the urgency is high. A good rule technicians rely on is 'colour plus behaviour': match the warning colour against how the car is actually performing. If the Aston Martin Vantage still drives normally and the light is steady, you usually have time to plan a proper diagnosis; if performance drops or the light flashes, err on the side of caution and stop safely.

Frequently Asked Questions
Why is the Transmission Temperature Light on in my Aston Martin Vantage?
On a Aston Martin Vantage, the Transmission Temperature Light comes on because a monitored value crossed a threshold the car considers abnormal. It could be a simple, inexpensive cause or a genuine fault — the only way to be sure is to scan the vehicle and interpret the codes rather than guess from the symbol alone.
Can I keep driving with the Transmission Temperature Light on?
It depends on the urgency (high) and how your Aston Martin Vantage is behaving. If the light is red or flashing, or the car drives differently, stop safely and get help. If it is amber and everything feels normal, you can usually drive to a workshop soon — just do not put off the diagnosis.
How much does it cost to fix the Transmission Temperature Light on a Aston Martin Vantage?
Repair cost for the Transmission Temperature Light on your Aston Martin Vantage depends entirely on the root cause. Because the same symbol covers cheap and expensive faults alike, a proper scan-based diagnosis is the best money you can spend — it turns a guess into a precise, fair quote.
Will the Transmission Temperature Light reset itself on a Aston Martin Vantage?
Occasionally, yes — a Aston Martin Vantage can extinguish the Transmission Temperature Light by itself when the monitored value returns to normal. But a light that keeps coming back is a clear sign of an unresolved issue that needs a proper diagnosis rather than repeated resets.
