Are you sure it is a '39 De Soto OD trans? According to the Hollander, "cases of Trans. under our #113 to 126 inclusive bolt up to the bell housings."  #113 is the standard trans. used in the De Soto and Dodge and #125 is the OD trans. used in '38 & '39 Chrysler and De Soto. This is a non-kickdown OD - purely centrifugal.

 

What is the case number on the OD trans?

You don't use the bottom two holes. I helped install one in a '36. I was surprised the first time I removed one from a Chrysler and saw they used the 5th and 6th hole. The later R10s are the same way.
