Hi, quick question!

Can I fill oil back in gearbox from breather hole on the top?(of course the correct amount)

Is it right / wrong or can't be done anyway ?

GP 6 speed gearbox.

why would you do that?
Fill it using the correct fill hole, and 1 meter of hose.

Thats the gearbox breather.

The fill up hole is on the side of the box - when you look at the side of the box you'll see 2 plugs with an 8mm square hole in them, ones the drain plug, the other is used to fill it up

Ok, ok! I know the "correct" way but is it possible ?

Yeah no problem go through the breather

I changed mine for red line mt85

Redline will be mine too.

How to pull out breather cup? I can pull it up a little but it won't come off?!hmm

I think I filled mine by the reverse light switch

No reason why not but you need to be precise with your amount or you can end up breaking a perfectly good gearbox.

I would say still take the fill plug out of the side of the box so at least you can't over fill it, when it starts pouring out you know it's full

Just saves trying to fill from the front of the box

Sooo... I removed fill plug to check oil level and what a surprise! oil level was much lower than the correct spot.

1) Garage did not replaced oil when I asked them to replace it (I supplied 2 boxes of tutela)

2) 2 boxes of Tutela is not enough and fiat manual is wrong.
