clutch jerking/hesitation on acceleration from stop

binoy29 · 11-23-2014, 03:45 PM

Hello everyone im new to 370.com

my 09 370Z m/t keeps jerking or sometimes i feel hesitation on 1st and 2nd gear when accelerating from stop.
Ive read some of the members here saying that to launch at higher rpms.

im just wondering if there is sometimg that i need to be worried about. has anyone here in the same situation like mine? have you got it checked?

43k miles on my Z

thanks any information will helpful

Did you just get the car?? The 1-2 shift in our cars is a bit harder than some other MTs. Just have to feel it out.

This wil help with your problem.

Clutch pedal too soft/no feel? Remove the helper spring!

sorry i forgot to mention that i have the aftermarket helper spring already. it helps a lot but the jerking still there no matter what i do. its annoying. just wondering if anyone here has the same situation llike mine and if it was diagnosed with something not good..

hesitation as it bogs when trying to drive off in 1st? Does it happen when engine temps are over 180+ only? Thats what mine does. Like pre limp mode or something...

Shift in to 1st @~1600rpm - 2000rpm to reduce jerking on torque transfers to clutch, hold the clutch for like half a sec to a sec to let the flywheel n clutch to synchronize then let go of clutch completely when u feel the compete connection.

Shifting in to 2nd also tricky, get the 1st gear to 3k rpm then repeat that above after "clutch,"^^^

yes all this helps. thanks. are this things im experiencing with are common nature of 370zs?

mishuko · 11-24-2014, 05:34 AM

it's all to do with the timing and how fast you're releasing the clutch... when I first started driving I found that around 3-3.5k would give me jerks and 4.5-5k would be my sweet spot for first gear.

I then realized shift for how fast the car is going... meaning if you're revving lower ranges and shifting you need to be slow in your clutch, if you're above 4.5k you can be a bit 'faster'

this clutch is definitely one of the areas that adds 'character' to our car

thanks guys. at least now i know that everything is fine with my clutch. ill just practice some more, hopefully i get used to this jerking

You shouldn't have to get used to the jerking. It's possible to drive this car smoothly from a stop. You just have to be very deliberate with your shifting.

I learned one thing, after i learned how to drive a nissan transmission any other transmission is like butter to me.

PS changing ur differential bushings helps reduce jerking.

How so??

I didn't notice any improvement when I switched to my whitelines except for the reduced wheelhop.
