I got a 2008 TRX450ER. Friend sunk it. Then trans oil would spew out breather tube, ok understandable. Checked Trans, looked good but breather was milky. Flushed motor, trans, compression test c/w. Ran great for 4 rides and started spitting trans out again "milky", case fluid was norm. Oil level didnt change, radiator didnt change, but trans would start spitting milkoil, but trans was norm. What is going on, i have never hear or seen this. I am a seasoned mech and am truely lost. After each flush session it would be fine, i can run motor to 80% back to idle all day and no negative results, but when we gets it, all trans oil prob start up again.....LOST HELP???!!!!
