I do sometimes, especially when I'm downshifting to 3rd at 60mph+. You will notice that if the throttle is applied too far, sometimes "3" will blink on your dashboard if you downshift at a fairly high speed. THis means you will go over redline and the ECU is preventing you from downshifting for this reason. At times like that, you have to let go of the throttle to make sure you get the power you need.

fsttyms1,
there is no manual "rev matching" you can do in an automatic transmission. Blipping the throttle with the clutch disengaged will allow the engine to rev enough to match driveline speed before releasing the clutch, but there's no equivalent to that situation in an automatic.
Ferrari comes closest to what you're describing, but their paddleshifting transmission is a manual with computer aided shifting, in that during a downshift the computer disengages the clutch, blips the throttle (for you) then engages the lower gear for smoth shifting.
Again, an automatic takes care of this using its torque converter. The only way to do this in an auto is to **** to neutral , rev the engine, then put the car back in gear. There's no need to for this.

yeah, but trannies try to reduce the revs during an upshift.
Sometimes its not 100 percent smooth and you feel the lurch.
I have yet to meet an average or above average driver that can shift gears at full throttle smoothly with as minimal "lurching" as and automatic.
Usually you slam the gears in quick and pop the clutch. Gotta love the tire chirps when shifting from first to second!

Guys, here's a simple description of rev-matching. IT'S NOT POSSIBLE WITH AN AUTO TRANNY!
Rev-matching is putting the clutch in, giving a little gas to get the engine up to the correct speed for the lower gear, and letting the clutch out.
Double-clutching is putting the clutch in, shifting to neutral, letting the clutch back out, putting it in, shifting to the next gear, letting it out. (Double-clutching usually includes rev-matching, but that's the basics.)

The transition is much smoother.
