I think the 1-2 shift is pretty easy and smooth for me, but I am coming from an Evo IX which has one of the most notchy stock clutches out there.

Like others have said, just take it nice and easy between the 1-2 and you will be fine. Once you learn the feel and engagement points, it tends to smooth out more.

basically catch a glimpse of your tach when the needle is horizontal, then engage 1st while you count ichi ni san :icon17:

hope u get the lame joke at end :ugh:

Since we're on the topic, what about skipping gears?

When I drove the C7 stingray, I would often see a sign that said 1st to 4th gear recommended. Any qualms about doing 1->3 or something similar? Only on days when I want to be fuel efficient :P 1->3->6

u can skip gears if u want. i dont want to wear out the syncro's prematurely so i go through gears sequentially, or if doing a skipped gear downshift, i would double-clutch it.

This does absolutely nothing on our transmission. You may as well "triple-clutch" and hum a quick tune after letting out the clutch in neutral a second time.

3-N-1 easier to enter gate

but im thinking in my head cars without SRM..

let's say you're in 6th and drop to 4th... would you double clutch it?

Is it OK to go from 6th to 2nd at speed? I was wondering. I have SRM.

darkphantom 05-06-2015 09:21 AM

SRM here, so downshifting is no biggie, I usually go sequentially unless I'm coming to a stop/signal where I drop it in neutral.

However, going back to the question at hand - how would shifting from first to third or second to fourth affect the synchros?

Granny shiftin not double clutchin like you should

First, you need to understand how the synchros work. Google is your friend :tiphat:

Basically, you need to give it more time between shifts to allow the engine RPMs to drop to match the transmission speed. The synchros are designed to sync up one gear to the next when shifting sequentially. When you skip a gear, the synchros need more time before they are ready. If you enter the 3rd gear gate too quickly on a 1-3 shift, it will most likely grind. Even if it you don't hear it grind, you can feel a much rougher entry into the gate through the shifter even before you engage the clutch if you don't wait long enough. Some people just double clutch to give it that extra time.

I skip gears all the time, up and down shifting. I don't really see a problem skipping gears on the upshift if you are just cruising and not bangin' gears. Just make sure the rpm’s don’t go too far either way. Downshifting, I don't really care. If I can do a single downshift from say 5th to 3rd or 4th to 2nd when approaching a corner, remaining under redline of course, it results in more time with my hands on the wheel where they belong. From my understanding, on a full synchromesh transmission, gear speed within the transmission is sync'd to the shaft prior to engagement regardless of engine speed. While it does take time, it is fairly quick in modern transmissions. Syncing engine rpm to transmission rpm is primarily done to make sure car balance is not disturbed, causing loss of traction, especially on the down shift while approaching a corner at speed.
