I think he means he uses the engine rpms to slip into gear. say at 3rd gear 7k pop out of gear and shift into 4th when the rpms drop to like 4.5k ( not sure on the actual rpm values). it takes some skill and until you get it right a whole lot of grinding but it can be done. I used to do it on my s15 pickup, but haven't taken the time yet on the honda.
