I've got a student who lost reverse in his truck. On disassembly, it was obvious it had been flooded. Rust on steel parts and clutch fiber un-bonding from the plates.

I'm glad I made him air check the low reverse piston because it was leaking. Here's the crack in the case we found. Sorry for the fuzzy photo. I've had many hundreds of transmissions apart but this is the first failure of this type I've seen. Funny part is the piston seem to blow out easily on disassembly.
