OK, allow me a little leeway since I've driven about a thousand miles in the last three days and work the late shift (and if that doesn't work, I'm pleading blonde with early alzheimers).
How come... some cars creep when you lift off the brake at the lights... and some just sit there?
The torque converters are different. Some are closer to transfering motion at idle speeds than others. Or its a hill.
If you want a strange sensation at a light... drive a DSG equipped VW/Audi.
some are manuals...

+1 However, I try to remember to keep my foot on the brake while the stoplight is red to keep the halfwit behind me from driving up my ass.
Also, not all roads are flat...

I love it when big suvs pull up so close the the E30, you can't see the person driving.
A little brake drag enters into this as well.

05- up 3.7 Grand Cherokees (also some 3.7 Commanders and Libertys) have a really weird feeling if: you are on a slight grade (2-3 degrees), the car is idling in drive and you very gently touch the gas. The torque converter sorta locks/unlocks and creates a very unsettling 'rocking' feel. The Chrysler folks say it's normal.

Slightly OT - I once experienced a manual car that would creep slighly on level ground with the clutch out in neutral, and stop when the clutch was disengaged. It was about 17(F) below zero at the time.
TR7 Triumph 5 speed trannys had a pump in the transmission to circulate gear lube. The gears were made of plastic and in really cold climates the 90wt gear oil would thicken to the point that the drive pins would shear off; the tranny would then toast itself. The fix: drain the 90wt and fill with ATF.

Chrysler transmissions seem to do all kinds of unnatural things the Chrysler folks say is normal. I especially can't stand that creaking sound that just about all of them make as you put them in gear, and also occasionally make it when taking off or slowing to a stop. It sounds like something inside ripping apart. Maybe that's why Chrysler transmissions seem to rip themselves apart on a regular basis.
Yeah, the 'bang' when the trans is put in park (99-04 Grand Cherokees) is downright unsettling. They say it's a safety thing, it's venting fluid fast so it unloads the clutch packs quickly. Throw in the well known solenoid pack 'buzz', the emissions mandated weirdo cold shift sequence (stays in low a long time, won't go into OD, warms the catalysts up fast that way), the refusal to engage Drive if it's moving at all in reverse (have to come to a complete stop before the low clutch pack will engage) the hard shifts that come from the PCM's learning procedures and I hear a lot of bitchin'.
Yah, I've driven the DSG cars. +1 on the half-wit-up-your-ass thing, I try to give myself extra escape room for those guys. I just picked up a Benz GLK 350, if you lift your foot at the light, it sits like a dog told to stay.
My 46RE tranny in my Dodge has had all clutches and bands replaced with kevlar --and it's got a shift kit. Talk about bang when shifting gears - sometimes your head hits the back of the seat.
In our Fit, if you're stopped uphill & let off the brake it will roll backwards a bit. That was pretty odd feeling the first time it happened.
In addition to all of the above, inordinately high idle...(set too high, vacuum leak, etc., etc.,)
Then there's a strong tailwind...

Yes but the Chrysler folks will tell you it's normal for the trans to fail at 80-100K miles..
