You mean quick shifting right? A slow methodical or even 3 step shift isn't nasty at all. When I get back to the car I will check it out again.

BTW, I don't want to permanantly disable VDC. I just want to be able to start the car and have it off by default, but turn it on if I let someone else drive or there is/are water, snow, ice, or marbles on the road...........

Is pressing the button really that hard? It is just one tap. It could be like the Chevy system where you have to hold the button in for 5 seconds.

If you really want it there is a device available that basically presses the button for you on start up and you can still toggle it back and forth. Search the forums and you should find it.

I think KP technologies makes a module for the vdc switch.

FWIW, I have another stock 370 in the shop today... it "lurches" forward also...

DIGItonium · 09-09-2011, 07:59 PM

Yup... count me in. It can't be the shift gates. After a week of driving I wondered why the gearbox required more effort than usual to the point it was difficult getting out of gear from park and even shifting in all of the gears. I did the "lurch" test and confirmed it, but it's very minor.

When the car was in the shop with the new clutch and ZSpeed CSC, the master cylinder failed, too!

Also, the juddering issue is getting better. Guess it is still breaking in.

Is it stock, and does it clunk when you get in 1st?

Yes, stock . Yes, a "thud" when you put it in first

Ok about this issue, in my car the only thing stock Is the clutch/flywheel, I've put in the Z1 clutch line, motul 600 clutch fluid, helper spring & the TWM SS. My transmission is pretty much perfect as it does not "lurch" at all, but as my friend seeyabud86 stated the Z does not like to be redlined in first then quick shifted into second. The rest of my gears are fine 2-6 no problem. What I do now is just shift right before redline in 1st & I'm golden.

For what its worth: Drop engineering has transmission mounts that might help some of us.

So true... I can't tell you how many times i've grinded the **** out of the 1st to 2nd shift at redline. It sucks, because i know that i can drive... so at first i'm all like

... then i'm all like

hmmmm interesting

no lurch for me at all when clutch fully depressed and 1st gear engaged.

jordan3720 · 09-10-2011, 10:13 PM

I experience a similar problem to the one described here. When I'm slowing down to stop at an already very slow speed (about 5mph or less), when I press the clutch pedal and shift into neutral, I hear a loud clank, and the car lurches forward. Could this problem be relative to the shifting into first lurch and thud?

Mandingo · 09-11-2011, 05:46 PM

Strangely, I have always had a thud when shifting into reverse. Going into first is sometimes very difficult (embarrassing at stop lights) and I have to go back to neutral, clutch out, clutch in, then back into first and it usually works fine. I'm pretty used to that though b/c my old mazda3 and 330ci did this too. There isn't any lurch forward that I can detect but I'll try on a more level surface.

This is a bit off topic but the idea about realigning the shift gate got me thinking. My upshifts into 2nd were always very notchy and sometimes downright gritty for the first 4k miles. The only reason it got better was because I learned by accident that if I move the shifter closer towards the drivers side as I'm engaging 2nd the notchyness is almost eliminated.

Before, I would engage 2nd with more of a diagonal motion towards the rear and away from me. Now I pull the shifter almost straight back at first then, a sort of jog to the right to seat it in gear. Sounds ridiculous I know but it works. It seems like that particular issue could be related to the shift linkage and gate and not so much the transmission itself. OT rant over.

the reason you are getting a thud is becaue you are going too slow and the timing on the car is fighing the gear. try pushing slightly on the stick when slowing using the break and it will "slip" out of gear. normally it is about at idle that this happens because the computer try's to set the idle while your engine speed is decelerating. or just tap the gas verly lightly and give the stick a easly push to neutral and tada! there is always a point when you accelerate and let off that the gears do not completely touch and thats what you are creating.

I know I just hear the rattle/marbles-in-a-can thing when coasting to a stop (esp going into garage) and depressing the clutch. Also hear it when starting from a stop in 1st, but releasing clutch too soon. Other folks hear this too?
