The modern transmission fluids vary in color depending on the manufacturer. But some of the today’s fluids come in blue, green, and yellow, although these colors are not very common.

What the color of transmission fluid tells about your car?

This fluid suffers one of the most brutal conditions inside your car during its journey lubricating, cooling, and circulating around the transmission system. Most car manufacturers recommend changing the transmission fluid every 60,000 to 100,00 miles for automatic transmission, while for manual transmission vehicles, the range is between 30,000 to 60,000 miles.

During the course of time running your car, the transmission fluid changes in color due to heat, age, and worn. The fluid might be brownish tint as you packed a significant mileage on your car which is basically normal. Checking the transmission fluid, when it becomes light brown, you might be considering to make a good servicing soon.
