What does the change in the color of the oil in the automatic box indicate?

The absence of critical faults in the automatic transmission will largely depend on the quality of the transmission oil used. In an automatic transmission, oil is not only responsible for lubricating rubbing surfaces and cooling heated parts, but is also a working hydraulic fluid. That is why it is extremely important to regularly check the condition of the oil, changing it if necessary. It is equally important to read about what to do with old license plates ontario.

Automatic transmission oil check
Most modifications of automatic transmissions have a mechanical dipstick that allows you not only to check the oil level, but also its color and consistency.

If the oil becomes dark or brown in color, it is opaque with foreign metal particles, then in such a case it is necessary not only to change the ATP fluid in a timely manner, but also to repair the machine.
