Bob, FWIW, I recently had water intrusion in one of my BW CR2 gears, due to a bad oil cooler. I didn't discover it until about 8 engine hours after I estimate it happened. After draining the contaminated ATF, I flushed the tranny several times with clean ATF by filling it until it overflow, then opening the lower hose fitting and letting all the fluid drain into a pan. I did this about four times, then refilled the tranny, ran it for about five hours, drained and refilled again, and have since run about 20 hours. No sign of water, and everything seems to be normal, including temperature, as measured on the outside of the case with a Raytek gun and comparing with the other gear.
