If oil in the pan is turbid and it has yellow color chips - sun gear is guilty. The reason is that this structurally most loaded node does not receive enough greasing. The temperature and amount of oil affect the sleeves state. When 09G, 09K, 09M housing sleeve is worn it pores out the lubrication system pressure and as a result gears and the other sleeve suffer. If the automatic transmission oil temperature is more than 110 ° C so there is a source of overheating.
