I also wouldnt waste my time trying out that water-logged trans...
Its not only the delicate plungers and springs in the valve-block, there's loads of needle-bearings in the gearsets and the brake/clutch linings are made of a paper type material.
We all know what happens to paper in water--and after 7 years....Well.....
Best thing for it--Strip it down for curiosity's sake, just to see how a trans is made, maybe save a few spares like the B2 piston and toss the rest....
