My 6-speed manual ECO does this occasionally, too - so it isn't just the automatics. I believe it is the variable output fuel pump; the few times this happened, I had just gotten off the Interstate at around 70mph and it dropped to around 500-600 rpm when i stopped at the end of the ramp. So far it hasn't been an issue, but I am keeping an eye on it - it is a little worrisome when it first happens; feels like the engine is right on the edge of stalling.
