Gear reduction box

Hello there, hope you're all well.
Got my Zs for 13 months now , done 37k miles. Was wondering if someone has change the oil on a gear reduction box ? There is not mention of this on the service booklet, but saw a video of someone doing it on a Niro ev and the old oil looks very black an dirty.
Anyway I appreciate your comments.
Regards.

If you've done 37k miles in 13 months an oil change is probably a good idea.

Do you know by any chance what oil to use ?

It's the same stuff discussed in this thread:

I'm not aware of any Eu supplier.

Look at this website under engine.

Did you get anywhere with this? I’m wondering if you found any help with how to check / replace the oil?

My dealer changed the oil during year 4 annual service without being asked.
So it must be part of the service plan.

You are absolutely bang on Tim.
I have just checked the MG dealer service schedule "tick sheet" from my recent 2 year service.
Item 26 on the list states :- "Check drive transmission oil level, top up as necessary".
Item 27 on the list sates :- "REPLACE drive transmission fluid - every 60,000 miles OR four years, which ever arrives first.
Therefore it would appear that if @julianNino is covering about 37,000 miles in 18 months, then it is likely that the car will hit the 60,000 miles before reaching 4 years old anyway.
