Attention: TDR Forum Junkies 
I've been reading about the NV5600 because I'm thinking about converting to that transmission down the road. In reading the posts, I saw that some members are adding an extra quart to their NV5600.
I'm going to change the oil in my NV4500 in the next few days. Is there any reason that I should consider adding extra oil to this transmission?
Also, anyone know off hand what size hex wrench I'll need for the filler port on the NV4500?
