I'm still not sure about my method. I didn't want to have to look at the rpm and I've never been able to pinpoint it by sound, so I didn't like driving around blipping to rev match though it was the smoothest way. I found that if I was fast enough, I could push or pull the shifter against the next gear with moderate force as the rpm dropped and as it reached the rpm where it matched, it would pop into gear. No griding unless I didn't put enough pressure on it, but it wasn't as smooth as revving back up to rev match and slide it in on acceleration and not deceleration. What do you think about that method? It's faster, but does it put more wear on the car?
