Well, I am starting to narrow things down a bit. Did some careful observation and experimenting, and it turns out that the jerking issue only happens when the trans is in 3rd. Not talking about the shifter position, I'm referring to what gear it is in.

If you start slowing down while its in 3rd, that's when it starts that sort of bucking back and forth behavior. I'm starting to think that perhaps there is something mechanically amiss in the trans.
