As part of preventative maintenance I want to take an oil sample out of my 225 CVT Magnum (oil sample is cheaper than a new CVT). Dealer has a kit to suck oil from the top, and that's what you need to do to. Our older MX220 has a dip stick that you just stick the hose down the pipe and suck it up, the CVT doesn't, or at least I cant find it, only the sight glass. How does one get a sample from the transmission/hydraulic reservoir?

I see there are a few plugged up holes in the rear end housing around the hydraulics, could one just pop one of those plugs out and take it from there, is there a breather cap under the cab? Other thought I had was get a clean pail and a hydraulic hose with no end on it, just do a quick blast into that and sample from it. 

TIA
