Purpose and Specifications

SWAG 10 93 3889 is a premium automatic transmission fluid designed for Mercedes-Benz 7-speed automatic transmissions. This blue synthetic oil meets Mercedes-Benz specification MB 236.15 and ATF 134 FE standards, ensuring optimal performance, smooth gear shifts, and long transmission life.

The fluid protects your transmission by reducing friction, managing heat buildup, and preventing wear on internal components. It works across a wide operating temperature range, keeping your transmission responsive in cold starts and stable during highway driving.
