hi again "Queen Of Spades",
attached is a picture of a Remote_Spin-On_Oil_Filter_Mount, they cost about $40.00 US and can be purchased at almost any local Auto Parts Store. they use a standard Chevy V-8 spin on oil filter. finding/making a mount location and getting the fittings and non-collapsible rubber hose will be the hardest thing to do. higher micron filters are available to remove the smallest of particles, they will cost more (check flow rates).
Remember, it is to be mounted on the Suction Line that runs from the transmission to the Hydraulic Pump. my YM already uses a rubber hose splice on that line, so doing it is pretty easy and straight forward. the suction line is the larger tubing that has the screen at transmission that should be cleaned at every oil change.
this may seem like an over kill, not in my opinion though. knowing the oil is kept as clean as possible, even before it reaches the pump, should give confidence the hydraulic system wear will be at an absolute minimum. also knowing the seals will not get debris buildup that causes leaks / seepage.
hurm, the engine uses a decent filter, why not the tranny. fixing the root cause is the best fix.
