[QUOTE=Avernus,Feb 3 2006, 05:03 PM]ok I'm 16 and I own one of these wonderful cars. I've driven standard transmissions on 2 cars, a mazda B2200(truck) and an old nissan stanza
(car). i "learned" to shift when i was about 7 from my mom saying,"3rd" *I'd put it into 3rd from the passenger seat* then her calling another gear when she was ready to shift again.

 

what happens when you double clutch and don't double clutch? why is it bad for the synchros? i never thought this thread would still be alive since people were making fun of me for "not knowing how to drive." but apparently, no one else does either

 

Double clutching is used to spin UP the input side of the tranny. Spinning DOWN is not a problematic thing to do since all that is required is to let off the gas, push in the clutch, find neutral and the input side will slow down on its own. On a modern day manual transmission, this is only necessary to facilitate an easier downshift into 1st gear at speed. Ordinarily, the syncros are built to handle normal sequential shifting. Any differences in rpm between adjacent gears is something syncros can take. It's the skip shifting that makes the difference potentially so great that it taxes syncros.

 

thnx. i was specifically confused by why is it necessary to push the clutch in, let it go and push it back in, instead of just pushing it down once?

 

Actually, I was responding to a response to my original post. So no, I didn't skip any of the thread.

It's been awhile since this was first made.
