Car jerks if not shifted at right rpm???, What could cause this? Options

[str8thugginit4ya]

Hey guys, I know you're probably thinking from the title that I'm probably not shifting and driving the car right. But, I like to think that I'm an okay driver and I know a thing or two about how to drive a manual. My main problem that I have is that whenever I'm shifting from 1st to 2nd, or any gear for that matter, and I don't rev match it perfectly it jerks a LOT. Now I compared the jerking to my brothers Infiniti G20, and whenever I don't rev match perfectly when shifting, the clutch just catches the gear back and goes on driving. No jerking or anything. Could it be my bushings that are bad in my suspension? Or maybe my clutch needs changing?I know for a fact that I don't ride the clutch, but what could be going wrong. I'm not saying that I'M not doing anything wrong here, but I just wanted to know if this is a sign of something going bad??? Any help would be appreciated.


-Thanks, Ryan

its really a two person job.... theres a good chance its in the synchros too... but the slave cylinder is located on the transmission itself... the master cylinder is against the firewall... master cylinder has the fill spout on it and the clutch pedal is directly attached to it... its right next to the brake fill spout and diagnosis box, right below the windshield line... you really just need to check this for leaks... if you do have a leak you're going to notice your clutch fluid going down... obviously make sure the fluid is filled as well... the slave cylinder check is a two person job... if you follow the line from the master cylinder... it runs right to the slave on the front of the transmission... its a plunger inside of a sleeve... to check it... push the clutch pedal in and hold it... at this same time have someone watch the slave cylinder... it will retract if its bad while the pedal is pushed in... wait about 15-20 sec to be sure....

important... are you getting any "grinding?" or just like rough shifts?

My 3rd gear alone grinds, but that is because the synchros are shot in the third gear alone! All the other gears have no grinding. But nothing with rough shifts. The only other problem, other than the third gear, is that if I don't rev match the shifts then I would get a jerking. It's not a MAJOR jerking like it's going to stall out, but it kind of annoys me because in ANY other car I don't get that. It shakes the whole car back and forth a couple of times.
