Greeting's: There seems to be some confusion as to what the Fluid Drive & M-6 Semi-automatic transmission have in common. The answer is Nothing. The Fluid Drive Unit replaces the Fly Wheel & is separated from the trans. by the clutch disc & does NOT use 10W motor oil. The F/D Unit requires a special oil which I have been unable to locate. I have used hydraulic jack oil in the F/D unit for years with success as it is a non-foaming oil, specific for pressure applications. WARNING ! Do not remove the F/D plug when the car has been driven. It is recommended, to let the Unit cool over night as a safety precaution. The M-6 Hydraulic operated transmission has an oil pump in the trans. similar to the eng. oil pump & operates by virtue of a solenoid, governor & hydraulic pressure. Fluid capacity is three pints and 10W "NON"-Detergent motor oil is recommended. That's All Folks Jim There may be literature on the F/D and Transmission on the 1939 page. http://www.imperialclub.com/yr/1939/limo/martin/index.htm

Thanks Bob!Apparently you are "right on" with the 10W motor oil in the Fluid Drive. I've had several replies with the same answer! I'm still looking for what is called a "Propeller Shaft Center Bearing according to my 1948 Desoto parts book. I don't have a Chrysler parts book but I would imagine they are the same. I have parts numbers according to the parts book but no way of knowing where to find them.Thanks for your most appreciated reply! :-)
