I bought a 04' Polaris 330 Trailboss. The previous owner started taking it part for some reason. I bought it as a basket case. I got it all together and running good. The transmission was missing the drain plug,dipstick and a top piece. It was stored outside. So I am sure the transmission got a lot of rain and water and dirt and was pretty stiff in there. I can feel it being tight. I am going to make a concoction of fluid to loosen it up, any ideas? I am thinking ATF type F and Marvel MO. 50\50 mix. Any ideas to free the bearings, gears a d silent chain up from years of neglect.
