5 year transmission fluid change

Hi although my 2019 SL400 has only 47,000 km I decided to change my transmission fluid and plastic oil pan when doing my yearly service (not an official MB dealer). Too early?

My transmission oil and filter on my 2020 bought new SL500 was changed last month. It’s every so many 1000s of miles or 5 yrs. Only done 12000 miles though but it’s covered under another 48 months service plan at £49 per month

nope, that is a good time based interval.
