[Tajefe Couple]

Mine won't rev past 3k in neutral I believe that's the limit, would have to check. However I've hit the tap-shift down to first sooner than wanted(hand on paddle, bump in road) and it went to 5k right away. Yes mine is also a 2LS. I have no control over when it up shifts though, just the highest gear it will shift into. So if I choose third it won't shift into fourth, and shift points seem determined by how much throttle I'm commanding.
Doubt any of that helped but yes my '12 will downshift when I choose as long as its not past the rev limiter around 6k rpm's I think, again don't remember number for certain somewhere close though.
