Bo,
I was wrong about the way the fluid drives get oil to the converter on the '52 to '54 Chrysler and DeSoto. After looking at a different more detailed cutaway, the oil from the main oil gallery. I guess they just leave the plug out of the back of the block. The late ones like this use engine oil for the fluid drive. When you change oil in both the engine and fluid drive, you add 10 quarts of oil to the crankcase and fire it up. The oil pump takes care of the rest. In the earlier ones like I have, the fluid drive sump is a self contained unit at the bottom of the bell housing with it's own oil pump.
I'm still rambling on back on the first page if anyone is still paying attention.
Regards,
Del
