well, aside from the syncro having to spin up the slower moving parts of the tranny you shouldnt have too much of a problem... but any time you drop more than one gear you are kinda stressing the syncros a bit to play catch up...

or does it just not go in at all?

if you want to go straight to 3rd from 5th, I'd highly recomend double clutching it. should have no issues then and will be much better for the gearbox.

Or can't you just do it Initial D Style and shift from 5th to 4th but leave the clutch in and then shift to 3rd?

I also rev match on all downshifts.. just blip the throttle to the RPM you are going to be at before you let off the clutch.

if your bushings are worn it can be extremely hard to "find" third coming from fifth gear as well.

as others have said, it's just more wear on the syncros. Your best bet is to double-clutch it.

You can go from 5 to 4 to 3, without letting out the clutch, but that's just excessive wear on the 4th gear syncros, which is unnecessary in this case.

Or unless your 3rd gear syncros are shot.

I have been able to drop directly to 3rd & nail it ever since I switched to synthetic gear oil.

I suppose.
Soooo, double clutching is:
Clutch in
Shift to neutral
Clutch out
Clutch in
Shift to next gear
Clutch out.

Double-clutching, lol just do this

Push in clutch
Move stick from fifth to neutral
Blip gas while clutch is still in
Move to third
Let out clutch

Do this all in one fluid motion, no need to double clutch. Practice x3

no, sorry, you're wrong. See the post before yours.

in your method, that's just rev-matching...it has nothing to do with double-clutching.

Zach: Thanks for the ignorance check

I remember reading that you have to clutch shift to neutral clutch out and clutch in and go into the gear because if you just shift clutch in at 5th and shift to 3rd and let out the clutch it doesnt get the driveshafts (not sure if it was this term) to get spinning the same speed as the engine is turning. Someone correct me if im wrong or rewrite it so people can understand.

Most of us actually don't use a clutch at all, unless in low gear or in reverse.

It isn't needed. The powerband is from 1200 rpm to 1800 rpm. There's either 10 or 18 speeds. Just throw it into another gear. The teeth are always lined up (if you time the rev) because of the short revs.

That would be missing a step.

Proper double clutching involves matching the engine RPM as close as possible to what it was before shifting...

If that means blipping the throttle while in the neutral position, you will need too.

That's exactly it. There are a couple shafts in the transmission, but I can't remember their technical names. Anyway, yes, it gets all those spinning at approximately the same speed, so the synchros have less work to do.

You are wrong, and need to go read a couple of books on driving and raceing.

Rev matching is part of proper double clutching.

well, yes, you can rev-match during double-clutching.

but nowhere in your original post did you mention releasing the clutch pedal when the gearshift is in neutral.

Without that, it's not double-clutching.

Yes, I know plenty about driving techniques...test me.

In my original post in this thread I commented on that Zach almost had it right, with his description of:
Clutch in
Shift to neutral
Clutch out
Clutch in
Shift to next gear
Clutch out.
Zach did post and that does say releasing the clutch while in neutral. His description is essentially correct other than matching the RPM while in neutral.

So I don't have any idea of why you would say that it was not mentioned. Perhaps you are speed reading through the post/replies, or I was not clear enough???

maybe I was speed reading or something, who knows.

I thought you had ignored his post, and just said your own thing

I didn't mean to sound like an ***, although I did. That's just what I think about double clutching.

If anyone is vague on trannies this is a good article. I love this site: http://auto.howstuffworks.com/transmission.htm

From How Stuff Works:
"Manual transmissions in modern passenger cars use synchronizers to eliminate the need for double-clutching. A synchro's purpose is to allow the collar and the gear to make frictional contact before the dog teeth make contact."

bloody hell. here's a basic summary for anyone interested.

5th to 3rd:

push in clutch, change to neutral, let out clutch, substantially blip the throttle, so that the engine speed in neutral is the same as it will be when you let the clutch out in 3rd. this will match both the engine speed to the gearbox, and the internal gearbox speeds.
then push in clutch, shift to 3rd, let clutch out.

if done right, it pretty much eliminates wear on the clutch and synchros, and makes for a very smooth shift.
