Water in Transmission

[AlbertaRednek]

while changing the oil @ 6 hrs after break in I found the trans level was overfull and milky. drained the fluid and it was about 3/4 litre overfull and pure white..3095.

We got into some water but it didn't get above the fuel cap or bottom of seats. I inspected the vents and no water entered though them and i am positive it didn't get deep enough to enter in the dipstick ( which I will be installing a rubber expansion plug in because it doesn't seal well at all)

I am wondering if the bottom of the dipstick tube to the trans case is missing an O-ring..Has anyone had this issue ?

Transmissions are vented to the atmosphere, and during the heating and cooling cycles, condensation will occur inside the case. This typically occurs when the vehicle is used for short periods of time. Short being defined as less than 30 miles whereas the lube never gets heated enough to allow the moisture to dissipate. Some machines, due to design, are more prone to this occurring. Some Polaris SxS's are very prone to this occurring in their smaller engines.

Also, when a hot gear box hits cold water it rapidly cools. This causes the air pressure inside the gearbox to reduce as the air molecules contract. This in turn causes air to be drawn in via the breathers. If your breathers are below the water level or getting splashed, water will also be sucked into the breathers. This can also cause air and water to be sucked in past seals as well.

Two explanations for moisture contamination inside a gear box.

You would be wise to change fluids anytime you submerge it into water past the bead of the tires. And also use synthetic fluid, oem mineral oil can rapidly turn to sludge if its not removed promptly.

Contrary to popular opinion these ORV 's are not designed to be amphibious vehicles.

Very good info indeed and 100% correct... After reviewing some pictures of our rip it appears the rear of the unit was fairly deep in the swamp. i would have to say the trans dipstick was extremely close if not sumerged in water. I am extremely confident the removal of the trans dipstick and installing a rubber expansion plug will cure this problem once and for all..

Even though im positive it didnt enter through the vents ( they are clean as as a whistle) i have relocated the vents behind the seatbelt to gain about 6-8" of height.. i may run it up to the roof yet.

a good drain and refill with JD Hy-Gard oil and she is good to go again......Hopefully:OhNoes:
