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

i can't believe that at all... i have an e153 tranny w/ LSD and poly mounts and i get no jerking at all on shifts... even if i don't rev match and thats a much sportier tranny than the s54... the springs may be shot on your clutch disk... the springs relieve the pressure on the plate and disc when the disc engages... if this is the case... either replace the clutch altogether or deal with it until you need a new clutch

Well I haven't gotten around to checking the Clutch Master & slave cylinder. So if all those are fine, then I guess well move on to that. Kind of in a tight spot for cash right now, so I guess I'll have to wait to replace te clutch. Are these all the problems that could be causing the jerking? Because I want to make sure I don't have to replace anything I don't need to.

Hey, I had/have similar problem to yours. I even made a post about it. http://www.6gc.net/forums/index.php?showtopic=70281&hl=

What I did today was a tune up. New NGK wires/plugs and a new rotor + cap. All of those items were original on my car since 1994 and about 110,000 miles or so!

Anyways, I did have some jerking aroun 1800 - 2200 rpm. Now the car drives much smoother and I would say 80% of the jerkiness is gone. I would also say that now I "have to try harder" to make the car jerk.

Hope this helps. Ohh, the car is a 94 GT 2.2L
