I come from the "Other West Coast", West Michigan, which is also known as GM, Chevrolet, and Corvette land.
Around here I am sometimes reminded of the difference between GM talk and Ford speak.
Besides "flexplate", known in Ford speak as an "automatic transmission flywheel" (or simply a flywheel), we have "Speed Control" which in GM talk is called "Cruise Control", and of course GM's "Positraction" in Ford speak is call "Equa-Lok" or Traction-Lok.
I am sure there are more, but those three are very common. GM and Ford enthusiasts are separate sub-cultures with different dialects. The GM types are typically beer drinkers, Southern Hill-Billies or simple farmer types, whereas Ford men are far more sophisticated and more attuned to drinking wine or bourbon, and owning a Lincoln Town Car.
