Ford - Shifters - Fiesta :: Is Ok To Shift Into Neutral At Stops?

This may be an old question: is it beneficial to shift into neutral while coming to a stop in an automatic transmission? But, my new Ford Fiesta has a PowerShift 6-speed transmission that behaves differently from a standard automatic. According to Ford, it's "like two 3-speed manual transmissions put together, with the dual clutch and shifting components controlled electronically."

Since the PowerShift is really a computer-controlled manual transmission (without a fluid torque converter), it's actually in neutral when I'm stopped and the shifter is in Drive position. I can feel it disengage as I come to a stop. However if I try coasting to a stop uphill, the engine still pulls the car upward at low speed without my foot on the accelerator. So the computer has to judge when to activate the clutch.

The issue is, I tend to apply the brakes lighter than average and decrease speed at a slower rate to come to a stop. So I think I might be confusing the computer, working against the engine before it wants to disengage the clutch, whereas most people would come to a stop more abruptly and the shifting action would have no problem. This is why I shift into neutral early in my slow-down phase, so the engine doesn't have a chance of pushing the brakes.
