Automatic Transmission: When Should You Change Its Fluid?

Some manufacturers describe transmission fluid as needing no change under certain conditions, but the reality in high heat and heavy use (towing, traffic, rough roads) is different.

Signs that call for an inspection

• Delayed gear engagement or shuddering.
• Dark fluid or a burnt smell.
• Engine revs rising during acceleration.

Practical advice

Use only the fluid specified for your transmission model; the wrong fluids can damage it. And ask a specialist technician about the right interval for the way you use your car.
