i have a Magnum 425 W958144. When I start it up the atv I hear a banging/rattle noise on the "Automatic/variable polaris transmission" case (the plastic case on the left under the driver seat).

If I lift it up a bit the rattle goes away… I looks like a FAN banging away on the plastic.

I’ve taken it to the Garage but they don’t seem to know how to fix it…

I live in Europe but I would like to try and fix it myself before going to a polaris authorized shop.

regards,

P.
