Yes. Overheating is one of the most common causes of transmission damage, especially in AMT o r automatic variants. Overheating can cause:

Fluid breakdown – Transmission fluid loses its ability to lubricate and cool.

Internal clutch damage – Heat causes warping, leading to poor engagement.

Sensor failures – Heat affects gear sensors, causing erratic behavior.

Premature wear of gears and bearings.

Warning signs of overheating:

Burning smell

Gear shifts becoming delayed o r erratic

Overheating warning on the dashboard in some variants

Preventive tips:

Don’t overload the car.

Avoid heavy stop-and-go traffic in hot weather.

Check fluid levels regularly.

Let the car cool down if it starts to feel sluggish o r smells burnt.
