proper fluid level on 727TF

Why would you not drop the filter? At high rpm this set-up is about ready to suck air.
factory put it out that way for years in stock location with out issues. i get ur point in droping the filter to avoid fluid run out. however not everyone has their foot in it thru the 1/4 so there has to be a stock minimum fluid level based on the aluminum case with stock height on filter?
