This is really dumb, but here goes. My 2004 Trail Boss 330 uses transmission oil, part number 2871478, per the MANUAL. However, I was given a quart of Polaris synthetic ATV gearcase lube, part number 2873602. Question: are these two interchangeable, i.e., can I use the 2873602 in my Boss' auto tranny?

Sorry, I can't find a simple answer to this on the web. You guys are it! Thanks.
