For all practical purposes they're a 3-speed. There's a very deep 1st gear but it's done in the Accel-a-Rotor section in the fluid coupling. The 1-2 shift is imperceptible and occurs before the car hits 5 miles per hour. It's the 2-3 that unnerves everybody. I heard it described once as "shudder-clunk-lurch".

Easiest way I know to ID one is to look at the pan. It covers both the case and the tailpiece.
