I think I'm Shifting Wrong

I did some basic obsevations on my way to work this morning. With SRM on or off, I get the same results. Smooth gear shifts under casual driving requires the following

Which is why I gave the details for a 3000 RPM shift as well

I did that on the way home and on the way in this morning and noticed the same.

I did notice too that if I waited a little longer to release the clutch pedal it was quite a bit smoother, like Scope said.

We got <10K mile out of the stock Potenzas with my wife doing daily highway driving. I switched to Nitto Invo rears in Jan 2012 and the car became my DD in July 2012. I just replaced all four wheels with new Nitto Invo tires in Dec after getting 20K on them. And I can guarantee you I was harder on those tires in 6 months than we were on the Potenzas over their entire life. I definitely let the tires loose on corners every so often, but usually I wait for a bit of rain - I can have a lot more fun for the same amount of wear on the tires

Does the Gear lock if you dont shift fast enough?

While I was driving today I was shifting to second, and I swear I felt as if it was locking. Then I started shifting Faster and it felt smoother So back to my question.

If you shift fast, Does that make it smoother? and If you shift slower does that make it seem stiffer?

Now thinking back I never shifted fast, but now Im going to start. It feels a lot better.

Maybe you just let the clutch out before you put it into gear?

I've done that a few times thinking, "Wtf?" then realized what I did.

Sometimes I do try and shift really fast and I do start letting go of the clutch before I fully shift to a gear.

LOL I dont do that anymore, I fix that issue.

Shifting from 1st to 2nd is a bit 'rough' than the rest, but you don't need to shift lightning-fast to make it smooth.

Smooth shifting is about the whole action from clutch-in/releasing gas then shift then gas-in/clutch-off.

Also, make sure you press the clutch enough thus the shifter is 'free'

Yea, but I feel like when I accelerate on first gear then press the clutch wait for 5 seconds because im going with the momentun and then I tried to shift to second it feel stiff.

But If I shift to second fast it feels a lot smoother.

5 sec is much too long. even at wot i only pause for the fly wheel to spin down into 2nd gear range for the smooth wot engagement.

5 secs?

Press the clutch a bit deeper and pull the shifter from 1st to 2nd smoothly.

You should be able to complete the whole shifting in no rush within 2 secs.

I'm remembering when i first got my Z too...

Give it 6 months of decent-******* driving and you will get the hang of it.

Well, you might want to try it ONCE(if you never tried this before) and feel it for yourself. But, do it in a large empty parking lot! Rev your rpm to 3k while holding the clutch and shift into the 1st gear. Then just dump the clutch and floor the gas pedal. It will bring your pleasure to a new level I bet you will love it. It's bad for your clutch and transmission IF you do it again and again. But dump the clutch is better than feather the clutch. And again, do it once just for your experience. Never do it on a public road!

Let me give you a quick Scenario.

Im driving down a 40mph zone straight line. Im on 4th gear. I Press the clutch all the way, Im still going at a decent pace with the momentum........5 seconds later when the car has slowed down to 35MPH I try to shift to keep going

Is that bad for the car? Should I not do that?

Sounds like you didn't shift into a proper gear according to the actual traveling speed or you didn't rev match correctly or you didn't rev match at all! Do you have SRM on? If you are at 40 mph in 4th or 5th gear and you clutch in too long, the RPM drops and you try to downshift without rev match? Then it will have some resistence to let you put into a lower gear coz that will damage your car.

With SRM on or off, I get the same results. Smooth gear shifts under casual driving requires the following ( Click to show/hide ) 1st gear accelerate to 4000 RPMs should be about 20 mph and push in the clutch. Shift to 2nd gear and release the clutch pedal as the RPMs drop to ~2800 (release steadily, not necessarily slowly, but not dumping it either). 2nd gear accelerate to 4000 RPMs should be about 35 mph and push in the clutch. Shift to 3rd gear and release the clutch pedal as the RPMs drop to about ~2500. If you change the 4000 RPM shift to 3000 RPMs then the engine RPMs will drop to ~2400 and ~1900 for 2nd and 3rd gears, respectively. Watch the tach needle when you release the clutch and see if it jerks slightly up or down before settling at the engine's desired RPM - if you see this or you hear the engine rev itself those are indications that you missed the butter zone for the shift (this is easier to see when the RPMs drop below the ideal mark) Note that all pedals should be operated smoothly without mashing on them or dumping them. My recommendation if you can't get to a track is find a large enough empty parking lot and practice these shifts (include 4th too if you have room) __________________ 2011 370Z 6MT Sport Gun Metallic \| ARC \| CJM \| Ecutek \| FI \| Fujimura \| R2C \| SPL \| Stillen \| TWM \| Z1 \| ZSpeed \|
