Transmission Temperature Light on a Honda HR-V
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 Honda HR-V
On the Honda HR-V, 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 Honda HR-V, 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 Honda HR-V 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.
Common Symptoms Alongside the Transmission Temperature Light
When the Transmission Temperature Light shows up on a Honda HR-V, it rarely arrives completely alone — there are usually subtle clues if you know where to look. Drivers often notice a change in how the Honda HR-V responds, an unfamiliar sound, or a warning message on the instrument cluster. Cataloguing these symptoms is not busywork; each one narrows the list of likely causes and helps a technician zero in on the real fault instead of replacing parts on a hunch.
- 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?
Why did the Transmission Temperature Light come on in your Honda HR-V? The honest answer is 'it depends', but the possibilities cluster into a recognisable set of causes. Knowing them in advance means you will not be caught off guard by a diagnosis, and it lets you sanity-check any repair quote against what commonly goes wrong on the Honda HR-V.
- 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 Honda HR-V
The right way to clear the Transmission Temperature Light on a Honda HR-V is to fix the underlying cause, not just reset the symbol. Work through the steps below in order — they move from the simplest checks any driver can do to the diagnostic work best left to a scan tool. Following this sequence prevents the classic mistake of replacing expensive parts before ruling out the cheap, common problems first.
- 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?
Whether it is safe to keep driving your Honda HR-V with the Transmission Temperature Light on comes down to urgency (high) and behaviour. As a rule, if the light is red or flashing, or the Honda HR-V is running poorly, stop somewhere safe and arrange help rather than pushing on. If the light is amber and the car drives normally, you generally have time to reach a workshop — but 'have time' is not the same as 'ignore it', so book a check promptly.
Diagnostic Trouble Codes Linked to the Transmission Temperature Light
If you scan a Honda HR-V 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.

P0740 |
Torque Converter Clutch Circuit Malfunction The torque converter lock-up clutch circuit is not responding correctly, affecting shifting and economy. |
Professional Mechanic Tips
Burnt-smelling, dark transmission fluid is overdue for a change — old fluid is a leading cause of overheating.
If this light appears while towing with a Honda HR-V, pulling over and idling in park (not off) lets the fluid circulate and cool fastest.
Frequently Asked Questions
Why is the Transmission Temperature Light on in my Honda HR-V?
Your Honda HR-V turned on the Transmission Temperature Light after its self-diagnostics flagged an issue in that system. Because several different faults can trigger the same symbol, the smart first move is an OBD-II scan to pull the specific code before you spend any money.
Can I keep driving with the Transmission Temperature Light on?
For a Honda HR-V, a steady amber Transmission Temperature Light with normal driving generally allows a careful trip to a garage. A red or flashing light, or any change in performance, means you should stop and avoid further driving until the fault is identified.
How much does it cost to fix the Transmission Temperature Light on a Honda HR-V?
There is no single price for the Transmission Temperature Light on a Honda HR-V; it ranges from a no-cost adjustment to a component replacement. The honest way to control cost is to diagnose the exact code before authorising any repair, so you only pay to fix what is actually wrong.
Will the Transmission Temperature Light reset itself on a Honda HR-V?
Occasionally, yes — a Honda HR-V 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.
