+1. If you are giving it some real gas, I find it much better to just preload the shift lever, release throttle pressure, it clicks into the next gear nicely, and then on the gas again. A fluid motion.
i hear preloading it is bad. once you do it a few times, it'll become automatic, if you just let of the throttle a bit and crack it back quickly, you'll realize when you can knock it in, and you wont need to preload.
the same thing applies for clutchless down shifting. though i wouldnt recommend doing it until you know how clutchless upshifting works, otherwise its the same thing, you just need to remember to get back on the gas enough to keep the rear from chriping.
