What causes "Herky Jerky" at parking lot speeds?

Settings are one reason. Main reason for it though is backlash in the drivetrain. The gears smash together pick up all the slack because of the collision they go back, collide with the other end then repeat. You add an engine, some gas pedal action, and an extremely low gear and that's what happens.

Bracing your right foot against the trans tunnel can get rid of much of it. A lot of it is due to it being right at that resonant frequency where it's affecting your foot on the gas and you're trying to compensate and you end up looking like a tool. Bracing your foot so it can't move can help it a lot. My car has always done it sometimes, and my diff & motor mounts are both new last spring.
