Hola All
What years of the V8 Powered Torque Fluid
Drive did De Soto have ... that did not have
a oil shared with the engine ?

I am not positive Roger but I think it could only be 1952&53. 1952 was the first year DeSoto had a V8 and in 54 used the Power-Flite transmission. Only leaves those two years as a possibility.

Thank You.

Roger, my 53 V8 fluid drive does not share oil with the engine. However, my 53 shop manual has information on the drive that does share oil with the engine. So I can not say. Also, my owner's manual refers to fluid drive and fluid torque drive - not sure what the difference is there.

Every Fluid Torque Drive has a two piece made of
Alum Bell Housing. The Fluid Drive Bell Housing
is one piece Cast Iron ( and weighs as much as
a bag of cement ).
The Unit I am looking for does not have a "tap"
into the Oil Filter Base Mount for oil that gets routed
to the Convertor.
If you have the S-16 and S-17 Brown Colored Factory
Service Manual some of pages have photos to compare
( I spent about two hours looking and re-looking
last night ).
The other thing that was pointed out to me was the
location of the Starter. The Sixes is not the same
as the Eight's.

Good info Roger. My 53 S16 car and manual fit the description you provided. So what does the fluid torque drive do that the fluid drive does not? OR vice versa.
The fluid torque drive is a torque converter while fluid drive is a fluid coupling. A torque converter multiplies the engine torque while a fluid coupling can't. A fluid coupling has 2 elements and a torque converted adds a stator which makes the torque multiplication possible. So the fluid torque drive is a more efficient design than the fluid drive. It wasn't around for long because the Powerflite was already in development.
Have a nice day

Thank you Steve. I checked my Bill of Sale and it shows TT shift with FL Drive so it looks like I do not have the torque drive. Oh well - it has been reliable.
The easiest way to tell, if you have Fluid Torque Drive( which uses the crankcase oil), or if you have just the Fluid Drive, is, to look at the front of the engine. If there is a flat, oil cooler, device, on the lower radiator hose, you have the optional Fluid Torque Drive. This option was only on the V-8.
Service manuals show a very good picture of the cooler. Also, the bell housing is longer. I had a 1952 Station Wagon, with the Fluid Torque Drive. My other 1952 Sedan, has the Fluid Drive.
