So i recently got a 2009 civic si. 301,450 km. When doing pulls in any gear and trying to shift you get a lockout that will prevent you from shifting over 6k rpm. As soon as the revs drop below that it pops right in no problem. It’s super annoying cause it only does it when you drive it hard and are trying to shift fast. There’s no grinds it just completely locks out like there’s a brick wall in front of the gear. Any ideas on what the issue could be?
