46 oz. of tranny fluid?

Just bought a 2012 850 Sports. Tour. HO – w/3600 miles.

I just took ALL of the plastic off and I’m changing all of the fluids, greasing the zerks, etc. My question is this……

46 ounces of tranny fluid came out of the transmission. The owners manual says capacity is 37 ounces. Huh??

How could someone have gotten that much tranny fluid in there? wouldn’t that have been over the "Fill plug"?

I did put in (1) one whole quart and none came out of the Fill plug. I guess I need a bit more.

Anyone have any thoughts on tranny fluid changes?

Thanks.
