I have a decent knowledge of how transmissions work, but I can't understand why a transmission would "bounce" or jerk when in low gears and not high gears.

What I mean by this is: When driving around in 1st, if you let go of the gas your car will bounce around and jerk like no other, but if you let go of the gas going 60 in 5th, it will slow down smoothly. Why is this?

physics behind the high gear ratio and..that's it. A blip of the throttle will send slot of torque in low gears vs high gear making it easy to "rock it back and forth".
