So I had a spare tranny stored outside this past winter for a couple of months. The plastic tote that it was in had a crack in the cover and water dripped into the axle holes of the tranny case. There wasn't a lot of water in there, but I could see it beaded up on the inside. What are the gears, syncros, blocking rings, etc. made? Are they susceptible to rust. I'm drying it out now and it still looks pretty shiny in there (as far as you can see).
