If it is a manual, dont' worry about overfilling. As long as you are on a flat, level surface, just bring the level to the fill hole.

"And before you ask, no, you cannot just pour the fluid through the shifter opening. It is a completely separate assembly from the transmission."

So if I was changing the fluids, should I drain the shifter opening oil aswell or leave it alone? There is a plug on the back of mine that looks like a drain plug and I would like to get all new fresh oil.

 

The oil in the shifter area should be changed as well.
