It's an '04 with just over 15K. I just drive it since it's a city car and was just checked out today with no fluid level probs. Honestly, the lag time to go into reverse is about 4 seconds.
That is DEFINITELY not right. It sounds like a manufacturing defect (in an accumulator maybe). I'd keep calling dealerships until I got a maintenance department with a sympathetic ear. There's no way you're going to get the full life out of that transmission.
Oh, it's not yours? Oh okay. Well, someone's screwing it up.
