C350 Service B
if possible always do it early

although it says 12k, i change at 8~ 9k
i did my transmission service at 40k too
i would change it though because the car already ran 80k
even spark plug i already change twice. My car already complete 50k
my bottom line will be 9000km for oil and 45000km for transmission
i use to maintain oil change for my previous Evo and toyota camry at 3~5k
and transmission service at every 10k.
