I have a 1991 mx-6 with a manual transmission. I decided to change the oil and the gear oil since it hasn't been done since I have owned it. When I went to add fresh gear oil I couldn't find where to add it. Where am I supposed to add new gear oil? Thank you for any help.

Anybody?

i am pretty sure it does not need gear oil
as it is a manual trans
i could be mistaken but i am pretty sure it does not take it
