IIRC--The DF used a five element converter--pump, turbine, and three
stators, do not recall any switch pitch being involved. Again, IIRC, the
tranny was 2 forward, 1 reverse, with a LOT of similarities to the Chebby
Power Glide. At the beginning, (late '40's) I think the only difference
between a Dyna Flow and a Power Glide was the name.
