Hi. I have a 99 Honda Civic. Recently when I release the clutch in first gear the car shakes. Why is the car shaking in first gear? I noticed it doesn't shake in 2nd, 3rd or any other gear except for 1st gear. What could be causing this?

both bad motor mounts/torque mounts and wroned out clutch can make your car shake at take off.

check your motors mounts. make sure they are not cracking nor broken.
if you see any motor mounts that are going bad or are bad replace all needed and see if its still shakes.

if motor mounts are good then you might want to start paying attention to your clutch for any excessive slipping which might need changing.

yeah ^^^ what he said
could be a warped clutch flywheel or just worn out

Did you mean transmission mounts when you said "torque mounts"?

brining this thread back to life!

OP did you ever fix the problem? Or does anyone else have anymore insight? I have the same problem

^This, or the friction disk/flywheel is contaminated with oil.

If it was the flywheel or clutch why wouldn't it shake in every gear. I am pretty sure that I am having the same problem as the OP and the shaking is extremely violent when taking off in 1st no matter how slow i let off the clutch or how much gas i give the car.

But when I take off in second, there is no shaking at all!

Sorry, don't mean to threadjack

Because of the greater forces associated with moving the car from a dead stop. It's a common symptom of bad/worn/contaminated clutch.

Quada

that makes sense, but why wouldn't it do it after taking off in second?

I still have the problem but it's only doing it when the car is driven for like 25 minutes and warms up. I don't have the problem when the car is cold or in any other gear except for the 1st. So I think the problem is that when I drive the car for like 25 minutes the friction on the clutch is building up and it's harder for the clutch to pull the weight of the car from a dead stop. After a while I found that the hood starts shaking also so I had to readjust the hood latch and lubricate it so it doesn't shake as much.

Does the hood latch have 8mm bolts or 10mm bolts? I have to readjust the hood latch today actually.

well it could also be that you dont quite know how to use a clutch right. too little gas when taking of will lug and shake the car too.

My car just started doing this today. Trust me its not this little shake like im releasing the clutch to quickly, it is more of a violent rupture! haha

Oh, and about 30 minutes ago I went to take it for another spin and it drove completely normal! I guess it's not a bad thing but WTF!

Anyway, I am still confused why IT DID NOT SHAKE when starting in second gear from a stop.

Globy, have you tried to start in second from a stop to see if it shakes?

Crash6066

yeah and i cant seeing it being a bad fly wheel. check to see if there is a leak anywhere near where the tranny and the block meet. ive seen it happen many times when the dizzy o-ring leaked and it dripped down onto the tranny

My wife was recently at a red light. When she went to release the clutch into 1st gear, the clutch stayed down and the car started shaking. She was able to physically pull the clutch back up and it is working again, but why would a clutch get stuck to the floor in the first place? FYI - Car is a 2001 Accord (not that it really matters).

Either your master cylinder or slave cylinder is bad. OR you have a hose leak along the line causing air bubbles in your hydraulic lines. (not sure what trannys accords have..... but if its hydraulic then ^^^^)

Maybe the release bearing got stuck for some reason.

I never tried starting on the 2nd gear. It will probably shake the car and stall if I tried it on the 2nd gear.

alright i decided to pull my motor this weekend to see what was up with this shaking. When I saw my clutch disk and flywheel it looked like everything was alright.

I did however notice some slight burn marks on my flywheel where the clutch was seated (I attached pics). Is this bad? Does my clutch look alright?

Another thing I noticed is that the passenger side axle (drive axle, right?) does not lock into place. Can this have an effect on the shaking?

And yet another thing was when I removed my tranny, I saw that the TOB was not seated on the fork properly, but I think I may have bumped this after I removed the tranny.

Any help is always appreciated!

ok im bring this back my flywheels and clutch have less that a 4k mi on it so i couldnt see how those could all of a sudden gone bad i ahve a stage 1 exedy clutch and fidanza flywheel

Oil on the clutch disk/flywheel can also cause chatter.

Quada

My problem was caused from my T-bracket splitting in half so check really well first.

00b18ek

but wouldnt oil cause chattering through all the gears not just first and if i start off in 2nd its fine....ill check the t bracket

00b18ek

i cant really find out till i take the car off the ground but would that cause a little rattle when im just sitting at idle and once the motor is under torque it stops
