Technical What is correct Gearbox oil?

[cyberbird]

Hello,

I'm confused about correct gearbox oil for my Fiat Doblo 1.4 t-jet 2017 year. I asked official serviceman about it and he said Tutela Gearforce 176 (his price is 30€ / L so I said I would think about it). But after googling I can't find anything else than Tutela Gearforce 75w (10€ / L). Is 75W the one he was talking about or are these two different oils? (My car has 6 gears)

Your gearbox is listed as requiring 1.76litres of transmission oil.
75w is the correct type.
Tutela is reccomend by fiat.

Is it possible that I could overfill the oil? In some cars you fill transmission oil until it starts pouring out. But here I think this doesn't happen. I'd rather pour 2L to be safe but I can meassure 1.76 Liter too if that is better.
I know some oil stays trapped inside so I don't know if this changes the volume i need to fill in.
