What an idea.

Right... wrong... smart.... stupid... would, could, should. So what?

It works the way it works.

To me it makes perfect sense to have an atomatic trans operating in manual mode to retain some of it's automatic features ... namely downshifting for me when I stomp down on the gas.

I chose an automatic because I did not want to be constantly clutching and shifting. I like the fact I can choose sport mode or manual mode.....frankly, the last time I used manual mode prior to this discussion was the first day I owned the car. Point is: I rarely ever use it and I think that's the way most people use/don't use it.

If I were driving a manual trans and a situation arose that I needed quick acceleration I would instinctavley downshift and go. Since I am accustomed to an auto trans and might occasionally play around with manual mode, I might not instinctavely downshift in a panic situation. I know for a fact that if my wife accidentally put the car into manual mode that she would absolutly need the car to interperate her needs and shift accordingly.

After giving it a little more thought and reading a few different positions regarding the "Sorta-manual" mode. I would not want it any other way than how it is now. It is "Trick"!

If I'm running 50+ MPH and kick down the gas the response is immidiate. I'm only seeing this in lower speed/RPM ranges.

exactly what "response" are you referring to?
I just tried this in auto, sport, and manual modes. there is no significant throttle response delay. next time you try it, watch the tach. the rpm increase right away, as the transmission downshifts usually more than one gear. then you feel the thrust in the seat. this is how it is supposed to work, if yours doesn't then you may have a problem. but I think what you're experiencing is the delay in the car's actual acceleration.
for example I left an intersection and was at 20mph and stabbed the pedal, rpm went to 3000 then 5000 as the tranny went down two gears. I didn't even get it all the way to the floor and the engine was fairly screaming, then it really started to pull since that's where the power is. this all took maybe a second.
