Shifting without the clutch

[sickpuppy1]

Truckers do it all the time, but the dont have sychro's and they are designed for this type of shifting after leaving low gear, I've heard its not good on the synchronizers also, but I'm no tranny expert. Funny, heres a video for ya, its called rev matching.

Rev matching = double clutching. The idea is to make the two shafts spin at the same speed before they come together. You can do that during the time the transmission's in a "neutral" state between gears without the clutch, but unless you can control the throttle so the gears have zero load on them as you're disengaging and engaging them, you're going to stress them more. The clutch is there to be used. Clutchless shifting is something to do in an emergency.

Its not the same thing though. They end up doing the same thing, but are done so in different ways.

after all the drama in this thread, and watching that video on how to shift without using the clutch, I decided to try it. It worked surprisingly well... no grinding, no loud noises, just a slight bump when shifting. I cannot vouch for it's long term reliability, but it seems like a handy skill if you ever need it (hurt leg, clutch problems etc.) Sayuki handled it like a champ.
