Transmission fluid service - do I really need it??
Q: Do I really need to change my transmission fluid in my Mercedes Benz?
A: This service replaces the worn automatic transmission fluid with new fluid, filter and gasket. Automatic transmission fluid is subjected to very high operating temperature, friction load and contamination from normal amounts of clutch material wear. New fluid and filter are necessary to maintain proper shifting, as well as prolonging transmission life expectancy. The constant upshifting and downshifting in traffic paired with extreme climate changes causes the fluid to break down sooner than in other driving conditions.
