I must confess ignorance as to what, specifically, was done to the HD PowerFlite transmission in our ’55 C-300 to stop it from leaking. It may have been a sleeve with an external seal. I just kept throwing money at it until it stopped leaking. I don’t think they leaked when new. I do recall my tranny mechanic using the round end of a ball-peen hammer to create dimples around the bolt-holes in the pan. Pounding from the inside out created small Belleville springs that added a little compression to the rim around the edge of the pan and underlying gasket. Over the years, repeated removal and replacement of the pan had dished the steel pan rim at the bolt holes slightly with resultant reduction of compression between the bolt holes.
I do recall a shared wisdom from my Fluids instructor at Iowa State who gave us the first law of hydraulics: “Hydraulic systems leak!”
Or, maybe Socrates had it right, “There is no solution, seek it lovingly.”
