VVTI oil change

[sceh]

2004 Yaris VVTI with the MMT box. When I change the oil in the engine does this also change the oil in the box or is there another filter and another sump?
Dumb question I know but my Haynes manual conveniently says the MMT system is not for amateurs so it has no details of any kind..

Thanks for any advice

I don't really understand your reply - sorry. Can you expand?

MMT=multi mode transmission, or also a robot gear.
Its a manual gearbox with a shifter robot, a kind of automatic.
But it has gearbox oil as all other manual, but probably no filter.
