Your Mercedes Benz gearbox is a very sophisticated piece of engineering that needs to be looked after with regular oil changes. The smooth system is computer controlled with very fine engineering tolerances. If the gearbox oil is dirty, it will damage other parts and affect performance.
Dirty oil can overheat the gearbox or cause the gearbox to burn out. This will lead to poor gear selection, loss of drive and transmission failure.
Your Mercedes Benz 9G-Tronic automatic gearbox oil and filter should be replaced every 77500 miles or 5 Years [whichever is the soonest].
During an automatic gearbox oil & filter replacement, we check the gearbox and look for any leaks. We drain the gearbox completely and replace the oil filter before filling it with high-quality gearbox oil that meets manufacturer standards.
Your gearbox must be cold when we performed this procedure which normally takes two hours. As a result the vehicle must be left to cool in our car park for several hours before we begin. We would require the vehicle for a total of 8 hours.
