Purpose
The main purpose of automatic transmission oil is the lubrication of the mechanical components in the transmission. As with engine oil, transmission oil loses its lubricating properties over time, which leads to an increased wear of the components. We therefore recommend changing the automatic transmission oil, even when it is not required by the manufacturer.
