My 99 C280 has the sealed for life 5 speed automatic. That is no change of transmission fluid is required. I have been told to have it changed anyway, some suggested mileage was every 30K, and 50K. What do you all think? Leave it or have the tranny service and at what mileage, I am a comservative driver. Never go over 100MPH.

 

50k is still fine.

 

i have the same question about my 94 c280. i was told that you dont get the fluid changed in it either?? is that true?? it has the 4 speed automatic and i was a tad sceptical about never changing the fluid

 

the oil that mercedes-benz use for the transmission is not the lifetime oil... but just the ordinary ATF.

bmw use lifetime oil, and the color is green.

still changing the mb oil is good to prevent shifting problem.

 

well where my dipstick would be there is a plug in the tube that says" mercedes workshop only" hmmmmm????[:-]

 

the dipstick is considered now as special tool and can bought locally.

on changing the oil, you only need to put in the recommended quantity. we only use the dipstick (engine oil and ATF) for checking.
