Shock after shift from 1st gear to the 2nd.

[yoyo]

When I drive the car from static, step on the gas untill the rpm is 3000 or more and then quickly release gas pedal completely and then shift from 1st gear to the 2nd one, and quickly apply gas again, a shock will be felt. The similar shock is also felt when I shift from 2 to 3. Is this the same as the idle problem?

shock? what do you mean by shock? is it a vibration or a jerk through out the car?

Have you tried altering your driving style to see if that helps?

Otherwise check out your motor and transmission mounts and see if they are worn, torn or loose, as they could be part of the problem.

+1 to changing driving style. Shifting isn't GAS OFF, CLUTCH IN, CLUTCH OUT, GAS ON, each shift should be a smooth transition in and out of applying power.

Get a feel for the drop in engine speed between shifts and let the clutch out (smoothly) when the engine speed has dropped appropriately while slowly easing on the accelerator to prevent excessive engine braking. If you just let the clutch out with the engine still at 3k the car will jerk as the engine is forced to match speeds with the transmission.

I mean jerk. Jerk is more accurate.

don't mean to jump in on the mp5 forum but I am pretty sure your motor mounts are going bad, especially the rear mount. Check your tranny and passenger mounts for any rips. You can check the front as well, they are pretty easy to check. The rear mount is challenging but can be done, just grab a flashlight. You may have to put the car up on a lift to get a good look at the rear mount, but if all the other mounts are decent, the rear mostly likely may be going bad. When I replaced my front mount, it was ripped to hell and when I did the rear, the rubber material was pretty much gone. Hope everything works out for you.

Is the shock after your foot comes off the clutch pedal, or happening while you release the pressure on the clutch pedal? Assuming the latter, it usually means you are releasing the clutch too fast, let it out slower. This will let the clutch grab a bit more slowly which will bring the transmission and engine into rotational sync gently. If you just yank your foot off the clutch (worst case), they will be spinning at different speeds, and then there will be a big bang when the two are smacked together.

If you have been driving a manual for a long time and the car just started doing this then it might be a clutch issue. If you just had clutch work done it may have moved the point where the clutch engages up or down along the pedal's throw, and you will need to adjust your pedal release to go slowly over the new engagement point.

Shifting at too low an RPM can make the car jerk as the motor tries to spin back up, but 3000 should be high enough that this isn't the issue.

The jerk happens when I release the clutch and (I think) when the two parts join each other. I found the reason: the rpm drops so slowly after I release the gas pedal. And before it drops to the desire value, the clutch has been released. I think this is abmormal. I have driven 10+ manual cars before. None of them was like this. Do I need a light flywheel?

Sounds like motor mounts to me too they are notorious for tearing usually not in a stock p5 but I would start there most likely the rear just under the intake mani and passenger side

my car has 137,000kms, and this similar thing happens to me in 1st and 2nd, even if im finding a parking spot in 1st and i add a bit off gas the whole car jerks, is it possible my mounts are going bad this early?

Everybody go get motor mounts

I get a shock too. Shocked that my car won't accelerate faster when I let the clutch out.
