Transmission Oil

[Eljosh]

Hey guys,
So I have a Getrag 260, and I want to change the oil in it. So I was looking around for what kind, and found out that there a few different kinds. So mine does not have a label that I could see and has a 17mm hex plug. And I want to just double check that it is MT-90.
Thanks.

This question has been covered a LOT recently. Please search next time.

It's most likely to be a gear oil transmission if it has no ATF label. 75w90 or 80w90.
