A couple weeks ago a great group of guys from here on T4R (

We succeeded but not without some hiccups...
I decided to try a "small puddle" that I had no business being anywhere around. It did not go well and ended up with me being stuck in muddy pit while water poured in from every nook and cranny.
I stayed right here for much longer than I would have liked. The guys did a great job of quickly moving into action to save me. A quick winch pull and I was watching many many gallons of water pour from my 4Runner.
It didn't take long to discover that I have managed to intake water into the transmission. Two of the guys ran into town for supplies, ATF, Air Filter, Headlight Bulbs, and everything needed for an oil change. Luckily we didn't end up needing the oil change but the rest of it was needed. We drained a gallon of ATF, filled it back up, ran it a bit, and drained another gallon, rinse and repeat until we had 3 gallons through the transmission.
Being as how we were in low gear most of the trail this got me back up and going for the rest of the trail. It clearly became a bigger issue once we got back to the highway. On the trip back home we stopped three times and ran another three gallons of ATF through it to limp her home. To her credit she got me all the way home under her own power.
She has been to the mechanic for a complete fluid change but the damage to the transmission has already been done. I can drive her around to work but the transmission slips and will need rebuilt or replaced. Which works out somewhat as the rear main seal has started leaking quite a bit of oil (probably due to all my abuse of her).
My biggest lesson from this trip was that while this website is a fantastic source of information... TRUST BUT VERIFY. I can't blame anyone for misinformation because I never actually checked where my transmission breather was. I read multiple places that it was located high on the firewall along with the front diff breather. Mine just so happens to sit directly on top of the transmission. I knew that this trip was going to involve water and didn't take the proper steps to protect my 4Runner.
