Probably from someone being a little too forceful with a water hose. That vent pipe on transmission does not have a check. It also vents engine oil and primary.

went out and looked at the vent tube, the way that it is mounted the hook portion of the hose is pointing down( like a cane) so there is no way that the water could get in there, mabe a little but not enough to make that oil look like milk, water would have to be actually sprayed upwards into the tube then make a 90* bend in the hose to get in there, when i wash the bike that area just gets rinsed with low pressure water then wiped out with a cloth. the oil was pure white. now does anybody else us the mobile 1 synth gear lube i their trans. and seen this happen? also changed early only about 4k since the last change.
thanks

They vent air. Oil and in your case water from transmission cannot go to primary or engine. Engine oil can go to primary if the seal behind alternator goes bad but that is rare. I had a alternator rotor spline go and all the metal from it took out the seal. I would think someone would have to stick the hose up from the bottom or have used a pressure washer myself to do that. Hard to believe enough moisture can get in there to make oil white. Sure it was not bubbles. It's an egg beater in there and no pump, so the oil is full of bubbles when you have just stopped. Totally normal. Would probably destroy and engine or automatic transmission with all those bubbles.

no it was not bubbles,, it was all white just like milk ,, looked like oil watered down ,, seen lots of oil with water in it as i work in a truck shop (peterbilt) and this is the first time my trans oil came out looking like this ,, i change every 5-6k and usually looks almost new when drained all the other times ,, so i was just wondering if it was the mobile 1 synth. oil .first time i have used it,, iam just concerned ,,
thanks

Go to advance search. I have see this dozen times here on the forum. I think as you and I quote, ever one sees it in new posts. I know I drive year round except raining and freezing weather. Bike sits Jan-March since I go South and leave the remaining working kids here. Quite often I have opened the garage door when we get one of those warm days and it's still cold in garage and have seen bike soaking wet with sweat. Sure its a little wet in the tank,transmission and engine. I also only change all three oils once a year. I personally have never see that.

If it were me...

I'd pull the top cover off the transmission, and check for broken gasket. Water pools between engine and trans when washing, bad gasket could let it leak in. Also, check the o-ring on the dipstick, same possibility maybe. Thought about condensation, but probably not a great possibility in N.M.

Good thought Def but oil can get thru a space water will not go. If there was a bad gasket or such, the way a transmission throw oil at 3000 rpm, oil would probably be all over bike. Maybe a NM flash flood during the night.
