Hoping to calm my OCD here a little with some feedback from you all.
Long story short, is .018% water content in ATF enough to cause damage or be of any concern?
I have a 2022 4Runner with 15k miles on it. I went off-roading about 2 months ago and got mud all over the undercarriage. I spent an hour under the car with a garden hose and a pair of diving goggles to throughly clean off the mud since I didn’t want it to trap moisture against the frame and cause rust to form. It didn’t occur to me until a week ago that the transmission breather is a 2 way breather and after checking where it lives, I’m pretty sure I hit it directly with a garden hose on full blast.
I ordered the exact breather and some vinyl tubing to make a test setup to see how much water I could have introduced in the worst case scenario.
I measured the distance from where the garden hose nozzle would have been to the breather on my 4Runner and the rough angle at which the water would have hit it at. I figured worst case scenario I hit it directly with the garden hose for 30 seconds so I went out and sprayed my test setup in the same manner for 30 seconds and measured how much water it collected.
I measured 2ml of water collected. My transmission has a capacity of 10.7l according to what I found online. I calculate that to be about .019% water content.
Is that enough to cause damage or be of any concern? I’m contemplating sending a sample in for analysis or potentially doing a drain and fill/transmission fluid exchange. What are your thoughts?
