I own a B5200 4 wheel drive Kubota, I recently had a woods loader installed, just tonight I checked the tranny fluid, it was topped (way) off and white, also it was white on the hydro connectors,, so the whole system is contaminated, I can only guess that the water enterd while it was sitting outside this rainy summer with a crack in the shifter boot,..anyways,..how would I go about flushing this system,..do I need a pump or just run it through with new fluid a few times,..or,..bring it to the dealer?? Im good with mechanics, but have not worked on this tractor before, other than (engine) oil changes,...any advise ?? Thanks in advance....
