Car jerks going from 1st to 2nd Gear

[Sparco_GSX]

The jerk is slight but noticeable as the clutch fully engages in regular driving. I.E. I'm shifting before full boost is reached. I have a recirc kit for the BOV so it's not that I don't believe and it does it whether it's warm or cold (engine temp)
It is laid up this winter due to road conditions so this trouble was just happening this summer. It does not jerk when I shift at higher speeds from first to second after 5-6000 the jerks stop. I can drive stick in heavy traffic, but this is my first performance car. Anyway I want to get work done on it before the spring/summer and am wondering if I should be concerned. Also the tranny and rear axle were replaced a few months before I bought it.

Is it a result of the mods, bad shifting on my part, or a far worse problem. or possibly nothing to worry about
P.S. my mods are in my profile

well as a new driver to the performance world i can see your point.


does it jerk once or multiple times or forward or backward?

if it does it once and the RPMs shoot up it sounds like bad shifting. the easiest way to fix that is to tap the gas before letting the clutch out into the new gear. this brings the RPM of the Engine up so that it can match the RPM of the tranny more easily and results in a smoother shift.

you said there was transmission work done? if the clutch is newer or a racing clutch, they have a higher tendency to grip more and can be a little more rough when shifting than a clutch that has been broken in.

basically, practice shifting.


if you dont think this will solve any of your problems then i wouls check the quality of the tranny work that was done, find the person/shop that did it and ask around to see if they are reputable.


i am sure someone here will know more than i do

Thanks it is an ACT 2600 clutch, also it jerks once almost as if the engine stalled but the car doesn't die and isn't in the process of dying It's just first to second. anyway i've got bigger problems now... Taking engine apart and replacing pistons, I bought a Lemon, Oh well the experience is good for me.
