Do I need to change the gearbox oil? if so after how many miles. the car is Mercedes c200 auto.
Every 50,000 miles is a good bench mark. Mercedes recommends a specific oil for your transmission.
I suggest you visit you local dealer and either have them do the job, or supply you with the oil and filter to do it yourself.
You will need to measure how much fluid is removed to refill. The torque convertor needs drained to and needs a ( #40 ?. ) Torx to undo the drain plug.
Total dry fill is 8.5 Quarts US. You will be able to drain around 7 Quarts if you drain the torque converter or about 3 Quarts if you only drain the pan.
I usually recommend 30,000 to 40 ,000 mile intervals if the vehicle is frequently city driven or a grocery getter. If it is a mostly highway driven vehicle, then 50,000 miles. .
