Double Clutching is quite literally syncing the 2 shafts without having to use the synchro to do it. When you double clutch your synchros do almost no work.


Edit: that civicforum link is specifically asking about the clutch/engine. Double clutching means you are pressing on the clutch pedal more often but usually when a double clutch is performed so is a rev match. No extra wear or stress occurs on the engine (probably less due to rev match) and the clutch is doing a negligible amount of extra work. The only thing that's actually getting more use is the throwout bearing. Reading that thread cost me 2 IQ points. I feel dumber after reading it.

I have read, from Road and Track, I believe, that double clutching is better for the car IF done correctly. I don't know what that means exactly, but I suppose if the target rpm were 3000 and you revved the engine and tranny to 6000 before slamming into the lower gear you would be doing more harm than good by your ham-fisted attempt.



It does take some skill, which some people have a hard time developing.

The though that one would be "doing it correctly" was assumed. Doing anything incorrectly is well... incorrect.

I have replaced 2 transmission on a2013 frs and i explain that car was 100% stock and alway be driven and shift below 3500 rpm an a bunch of people dont believe it and say that is drivers fault. I am in my 60 and i always drove manual and i never hsd to replace a transmission. Give me a brake this Aisin transmission is GARBAGE. Everybody has grinding problems and shifting problems and always is drvers fault
Aisin had the same problems on a Honda S2000 ten years AGO and still didnt figure it out!!!

exactly.same way how i feel. i hope the 2017 tranny will be much better
