Long story short, somebody hit me up about rebuilding their 32RH. Ok fine, lets talk. The story quickly evolved from "it needs a new pump" to "I took it to a shop and they tore it all the way down and then wanted $1500 to re-assemble it so I told them no thanks and collected all the parts in some bins and took it home." First off, a shop rebuild for $1500 is well cheaper than anything I've seen, and had it "only" been $1500 I might have never tried to rebuild mine in the first place. But I digress.
Then she tells me that some stuff "may have gotten wet", since she had the bins in her car port and they filled up with water after a couple of recent big rains. Yeah...that was probably a bad choice. I'm sure it's mostly just a light surface rust layer on the steel parts, and a lot of those parts aren't even in contact with other parts....but the input & output shafts could be a real problem, and the bearings inside the planetaries are probably trashed, who knows what else. I think all the valve body parts are aluminum, so I'm not too worried about it. But I also don't see all the parts (some thrust washers are missing, the rear band apply strut and the servo/accumulator pistons at first glance). And the amount of rust on the low/reverse drum (upper left in the pic) suggests it may have seen more than just recent rain.
You can seen in the pics that there is water ON the parts. What a mess. I'm probably going to acquire the bin of parts, just to see how bad it really is, and if some of the chemical remedies can bring any of this back to life. Some low effort stuff on my part. But if more than a few things end up needing replaced, she's going to regret not having just paid the shop for the rebuild. So yeah, don't take your transmission apart and then leave it out in the rain.
This should be fun to document if I end up acquiring these parts.
