Oh do **** off, you imbecile. I've forgotten more about transmission
design than you know about selling hacksaws.


Oh, and Dave - first automatic transmission I can find was the Manly-La
France hydraulic one of 1907, used on light waggons and delivery
vehicles. It was a variable stroke hydraulic transmission with a 5
cylinder radial pump and a pair of directly-couple hydraulic motors.
