I bought a clean "rebuilt" transmission off some jackass, and while it was being installed about 2 cups of water spilled out with oil particles. My partner and I tilted it completely sideways for a few min and nothing else came out.

I was just wondering if that requires a rebuild. The water looked clear with no dirt particles. I don't know how long the waters been in there either :cry:

After the water drained.. some sludge came out from the inside. Argh, i'm letting it sit at a weird angle until most of the sludge drains out. THere are still no signs of metallic bits.
 
It shouldn't hurt anything unless it sat like that for a few weeks, but if it was just sitting at the bottom of the case I dont' think you have much to worry about, You could have a disassembled and Cleaned whether or not you want to do that is your choice. Another (possible) option is just run cleaning solvent around in it, Not sure what ind though as some might possibly eat away the rtv sealant around the cases or you can run new fluid and change it every 100 or so miles to get everything out of it.
 
We have been getting a lot of trannies here for rebuild that have been sitting for a long time and got water in them. Some junk yards leave trannies outside, some people may have a leaking shed, who knows, but on a few of them the gear sets were bad. When gears rust, it eats the metal away and you will have holes and areas of the tooth that is basically gone. If you have a trans that had water in it for a long enough time and then run it, you will eventually break a gear. I'd say if the trans is nothing special run it. If it has expensive stuff in it, open it up, clean it, and take a VERY close look at the gear teeth, especially 1st and intermediate 3rd.

If the water wasn't rusty, I'd not be awfully concerned. Get some nice, cheap Sychromesh, run it for a couple thousand miles, and replace. If it wasn't exposed for too long, it probably didn't get through the grease coating the internals.

I wonder if any of these wet ones are coming out of New Orleans.
