Guest De Soto Frank Posted March 22, 2002 Share Posted March 22, 2002 "Calling All Experts"...<P>Am trying to identify a Chrysler Corp. overdrive transmission.<P>we're pretty sure that it's 1940, but wondering what it's out of?<P>Have found a flat boss on the left side of tranny, at the rear of the case, right at the parting line between the tranny & OD housing, with a number stamped there, beginning with "S-7..."<P>My theory suggests that this unit originally went into a 1940 De Soto (model S-7).<P>Does anyone know if Chrysler Corp made a practice of Stamping engines, transmissions, rear axles, etc. with the model code for the original vehicle application?<BR>(Original model codes went: C= Chrysler, S= De Soto, D= Dodge, P= Plymouth).<P>For example, the engine # in my De Soto starts out "S-8", indicating, 1941, model S-8. (Don't know if the practice extended to other drive-line units.)<P>If anyone can enlighten me about this, I'd sure appreciate it! Link to comment Share on other sites More sharing options...
