Transmission Temperature Light on a Toyota Auris
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 Toyota Auris
On the Toyota Auris, 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?
In terms of priority, treat this as a high concern on your Toyota Auris. The single most useful thing you can observe is whether the Transmission Temperature Light is steady or blinking: a steady light generally allows a careful drive to a safe location or a workshop, whereas a flashing light signals an active fault that can cause damage if you continue. Pay attention to changes in how the Toyota Auris drives, sounds, or smells, since those symptoms sharpen the diagnosis considerably.
Common Symptoms Alongside the Transmission Temperature Light
Alongside the Transmission Temperature Light, Toyota Auris owners commonly report a handful of related signs. Some are obvious, others easy to miss until you pay attention. Keeping a short mental (or written) log of what the Toyota Auris does when the light is on gives whoever performs the repair a huge head start and can save you money on diagnostic time.
- Transmission temp warning lit
- Delayed or harsh shifts
- Burning smell
- Transmission slipping under load
- Often appears when towing or climbing hills
What Causes the Transmission Temperature Light to Come On?
There is rarely a single universal reason the Transmission Temperature Light appears on a Toyota Auris; instead there is a shortlist of usual suspects. Root causes range from simple, inexpensive items to genuine component failures, which is why a proper diagnosis always beats guessing. Understanding the common triggers on the Toyota Auris helps you have a more informed conversation with your mechanic and avoid paying for parts you do not need.
- Heavy towing or load
- Low transmission fluid level
- Old, degraded fluid
- Blocked transmission cooler
- Stuck thermostat or failing pump
How to Fix the Transmission Temperature Light on a Toyota Auris
To resolve the Transmission Temperature Light on your Toyota Auris, resist the urge to simply disconnect the battery and hope it stays off. A warning that is cleared without addressing the cause almost always returns. The step-by-step approach below is the same logical order a professional follows on the Toyota Auris: confirm the basics, read the stored codes, then target the actual fault.
- 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
Is It Safe to Drive With the Transmission Temperature Light On?
Drivers ask this constantly, and the answer for the Toyota Auris is nuanced. A steady amber Transmission Temperature Light with no change in how the car drives usually means you can continue carefully and get it looked at soon. A red or flashing Transmission Temperature Light, unusual noises, warning messages, or a drop in performance are your cue to stop the Toyota Auris safely and avoid further driving until the cause is known.
Diagnostic Trouble Codes Linked to the Transmission Temperature Light
If you scan a Toyota Auris showing this light, these are the OBD-II trouble codes most commonly associated with it. The code you actually retrieve is what pinpoints the repair.
| Code | Meaning |
|---|---|
P0700 |
Transmission Control System Malfunction A general request from the transmission control module indicating a stored transmission fault. |
P0740 |
Torque Converter Clutch Circuit Malfunction The torque converter lock-up clutch circuit is not responding correctly, affecting shifting and economy. |
Professional Mechanic Tips
If this light appears while towing with a Toyota Auris, pulling over and idling in park (not off) lets the fluid circulate and cool fastest.
Burnt-smelling, dark transmission fluid is overdue for a change — old fluid is a leading cause of overheating.
Frequently Asked Questions
Why is the Transmission Temperature Light on in my Toyota Auris?
On a Toyota Auris, 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 Toyota Auris 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 Toyota Auris?
Repair cost for the Transmission Temperature Light on your Toyota Auris 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 Toyota Auris?
If the trigger was temporary, a Toyota Auris may turn the Transmission Temperature Light off automatically after a few drive cycles. If it remains lit, the vehicle is telling you the fault is still present, and the symbol will only go out for good once the cause is fixed.
