Water In Trans Fluid

West T · Mar 25, 2013

I was getting a head start on Spring the last couple weeks and getting the oils changed on all my equipment. Although after the snow that just blew through here this weekend it"s a far cry from the 85 deg we were seeing at this time last year. I"ll take the ground moisture though! Anyway, when I drained the trans fluid (I put in 15W-40 two or three years ago) it was a milky tan. I went back in with 10W-30 this time based on recommendations from John (UK). I believe the milky tan coloration means I had water in the fluid. My question is how does it get in there? This may be a silly question but I just can"t see where it would come from? Thanks.

Im assuming you keep it sheltered if not it can come in through the vents or shift boots fill hole ect. If you do keep it sheltered it is more than likely from condensation.

since you could not get the transmission hot, like plowing or disking,

it might be best to change the oil again this spring, when you can warm up the transmission.

you want to get all that water out of the system,
sometimes it may take hours for the system to all drain out and the oil needs to be as warm as possible to get the max old oil/water out,

Yep, just condensation can do it. If you were using it everyday, the heat would separate it and and evaporate it out again, I wouldn't worry about the color, but drain it all out, let it settle in clear buckets, and just toss the watery part.
