I've got a Getrag 260.

The wiki says it needs MTF 75w80. Is 75w90 ok or not?

Thanks,
:)

Think so,ECP recommend straight 80w for my 325,so it seems as long as it's there or thereabouts it's ok.

you need to make sure your oil is GL4 and not GL5 though.

Yeah,

I got it from ECP: "Triple QX Fully Synthetic gear oil EP 75W90".

"meets the requirements of API GL-4 & 5"

Confused :?

Is confusing aint it.

It used to be that GL5 oils would attack/damage 'boxes that were designed for GL4 oil,but obviously technology has moved on-it will be fine for your car.
