Ok guys, I haven't found any threads on this, so I'm assuming that I'm the only one with the problem.

When you decide to take your car suddenly, ***** to the wall, WOT, you redline the car, and you shift from 1st to 2nd gear, how do you get it to go smooth? The car jerks back and forth almost violently when I shift. I can't figure out how to do it.

The clutch grabs very high off of the floor, at the top of the pedal actually. Could this be the problem? I don't know how to adjust it. Has anyone else experienced the same problems?

 

You're shifting wrong.... are you letting the revs fall a little bit before releasing the clutch when in second?

 

slip your clutch more

 

Do you mean like a jolt forward when your take your foot off the gas?

 

It's driveline shock. You can't drive an AWD car like a RWD car; it's a different animal. In a RWD car, when you are slamming gears and popping the clutch in and out as quickly as you can, the tires will bark and the energy is transfered away from the driveline. In an AWD car, there is too much grip to "bark" the tires on the 1-2 shift, so what happens is all that energy is absorbed in the form of driveline shock.

This results in a jerky, lurchy feeling until the car resumes it's forward acceleration. What you need to do is let the clutch out a bit more slowly on the 1-2 shift and this will not occur. On the rest of your upshifts it doesn't matter as much and you can pop the clutch in and out like you would when speedshifting any other car. This will take a little bit of time to get the hang of, but once you get it, it'll be second nature and quite easy. Hope this helps...

 

That seems like it's the problem. So do I need to shift more slowly.....or just solely letting the clutch out a sec or two later?

 

Release the clutch slower.

 

The biggest thing you need to learn to do is rev match when you are shifting gears at higher rpm levels. This will ensure the rpms do not drop off, thus alleviating shock and minimizing power loss through loss of turbo spool.

 

You can't/don't need to shift AWD cars as fast as you do FWD and RWD cars. Just snick and go... but slower. You cannot slam shift these cars and not get the result you're getting.

 

yeah that happened to me when i first got the X and now ive learned my car and everything is fine now

 

so true.. i came from a 2000, 2002, 2005 STi then to a 350Z then back to a Evo X.. i struggled for the first week when driving the X coming from a powerful RWD 350Z. I must say.. thats the only thing i miss.. when the tyres bark from shifting hard 1-2.

 

Not as much as barking from 2-3 or 3-4

 

Being a recent LS1 owner..... I'm use to power on 1500rpm, and slamming gears .....No one told me you can't drive these like any other car. Isn't shifting slower from 1st to 2nd going to slow me down, obviously, during a race?

 

no..You can shift very fast from 1-2 w/o jerking the car bc i do it all the time. Its the timing of your shifting thats messing you up

who says you cant chirp tires on awd car?!! I used to do it with my evo IX all the time, sometimes even from 2-3rd gear

 

It definitely has a lot to do with the clutch and clutch master cylinder assembly and how high the clutch grabs. I shift the gears in my GSX as fast as possible and while using NLTS and its as smooth as butter.
