Rattling in 2nd or 3rd at low rpms
 

Just like a new parent, I think I've been extra sensitive about every little noise my car makes. I've noticed that when ever I'm in 2nd or sometimes 3rd, at low rpms (around 2-2.5k) I hear and feel a little rattle in the transmission, like something is loose and shaking around in there. I would guess that the gear isn't quite engaged, since I notice the same noise in my old civic when I don't get 1st in all the way. As I get up around 3k rpm, the noise slowly disappears. I'll be calling the service dept. of my dealer later today, but if anybody has some input, it will be well appreciated!

Next time it happens, place your fingers on the reverse lockout ring and see if it goes away. Rattles coming from that ring are common in 6mt Subarus at low revs.

Mine does it too, sounds like an old truck.

How much load are you trying to put on the engine at those RPMs in those gears? Low speed, high load situations aren't good for any car.

Speaking of, I always catch myself 'playing' with that ring when my hand is on the shifter. Not trying to pull it up, but just fidgeting. I know I can't be the only one... right? :D

I'm used to reverse gear being to the right and down of 6th, so this is somewhat new to me, but I like the placement more. Makes it easier to switch between 1 and R. Also like how the gear indicator shows R with a nice bold border, stands out!

Not very much. I usually notice it driving around during slow city driving, right after shifting up from 1st after starting from a stop, like at a light or something.

Hmm, sounds like you're driving her right then. Have you ever heard clutch chatter? Sounds like what you're experiencing. If it's not the ring like others mentioned, I bet it's clutch chatter. I don't remember if our car had it stock... We've got the Clutch Masters clutch and flywheel in there now.

Its most likely this. It can be very common and sounds exactly like the OP described.

Somewhere, on one of the sites I thought I read a service bulletin or something-of-the-sort that if customers complained of this to change to a different lubricant. I cannot for the life of me remember where I read this...

I think they also mentioned something about giving it to Zoomie so he could test thrash it for you also!:thumbup:

My car makes this noise under the correct circumstances. It's nothing that concerns me at this point. Sounds quite normal for the type of transmission.

The noise is from the transmission, not the reverse lock. It happens when traveling slowly at a load level that is almost lugging the engine.

I hope this noise doesn't become another BS warranty thing like what happened to the V160.... I'm sure that made Toyota upset.

Ishii

Nope, I'm always playing with mine.

I have this experience when I'm going too slow at a gear in which the car seems less comfortable in. I never imagined it being any sort of mechanical issue but more of just learning the car's behavior.

Let us know what the service people tell you :S.

This!

I get the same thing when I up shift too early in the city. I just figure it's the car telling me to rev it more next time.

:word: Due to the lack of a center arm rest, I'm always either pushing the e-brake button or messing with the reverse ring in traffic.

Back on topic, I've encountered rattling on more than one occasion. Slow speeds or low RPM's + moderate to heavy load will do it...but since you said you're using light load, it sounds a bit more serious.:iono:

This was pretty much what Subaru service told me, I guess I got used to up shifting too early in my truck, which has way more torque and could handle the low rpm+slow speed. I've been trying to be more careful, but the engine winds up so quick, I find it very difficult to stay in gear when driving around the city.

That's what she said... Couldn't help myself

I experience the exact same thing... I often semi-stop at stop signs and stay in second gear accelerating from about 9-10 mph (is this bad for the car? - obv I should be stopping at stop signs but disregard that for now...) when I experience "the shakes"

I find I need to get over ~10 mph to not lug the engine in second. I find the car can maintain speed at 2k RPM and preferring to accelerate over 3k.

Is it the entire car shuddering? I remember some taxis shuddering under acceleration when the rpm is low. Torque fluctuation? :iono:
Seems odd.

Picked mine up last night and noticed the same rattling. Kind if annoying.

Is this rattle people talk about happening under the hood or at the shift nob?
If it's under the hood, then I notice the same thing too.
Do you notice that noise happening when you are doing engine brake too?
I hear it both during acceleration and engine braking between 1500 RPM and 2000 RPM.

P.S. I know how the direct injection noise sound like and I'm not talking about that.

I noticed that the sound tube resonator box can easily rattle against the intake manifold.

It has soft rubber mounting.

The injector pump for direct injection makes a knocky / rattley sound. Its on the drivers side of the motor, on the top at the front. If thats where its coming from, thats normal.

Any updates?

Same thing here, but I think it's just clutch chatter.

Clutch in at low rpm and it goes away.

Same thing here. Automatic. I can reliably reproduce the issue going slowly (20-30 MPH) up a slight incline between 2k 2.5k RPM in regular drive mode.

someone find a solution :(

I play with that too often, through the car into Reverse at a light once! Never again though, - no more playing. Reverse lockout ring is not a toy.

i was under the car the other day, some of the undercarriage panels rattle around down there.. maybe its coming from there.. I didn't have anyone with me to test it out at the time.

There is a bit of gear rattle in these cars in first and second gear. It is nothing as bad as the noise my previous '02 Ford Focus.

If you lug the engines in first or second and accelerate you can hear the noise in my car. I would say it is nothing to worry about.




BTW, try not to rest your hand on the shifter, it could cause the shift forks to wear on the slider that engages gears internally. I do a little track driving instruction and a surprising amount of people hold on to the shifter.

Hey guys I'm experiencing the same problem as stated above. It's weird to describe, it's like a rattle or something is muffled or loose in the engine bay around 2-3k rpm. The only difference between me and the rest of you is that I drive an automatic.... What could be causing this sound? Just to reiterate, it only happens in low gears at low rpm. And it's on a lite load. I'm still trying to properly break in my new ride. Thanks

this is normal, low RPMs and low speed in 2nd gear, nothing to worry about. Had this noise in many of my previous MT cars.

Really? I picked my car up 4 days ago, and have heard a slight "metallic rattle sound" coming from what sounds like under the hood, on the drivers side.. (Right Hand Drive in Australia) It happens during acceleration from approximately 2,500 - 4,000 revs..

My last couple of Manuals did not make this noise?
Should i be worried?
Any1 had the same problem and found a fix?

I have this similar sound as well. i recently installed catless front pipe and thinking it causes this. I thought nut or bolt got lose on either overpipe to front pipe or front pipe to exhaust pipe section. I havent lift up my car to check it out to inspect bolts and nuts but i doubt it. if it got lose then i would hear loud tank sound from car or exhaust leak sound. regardless i am going to lift up my car this weekend and see everything is tight and secure.

Three or four possible issues:

For most, you're hearing the clutch rattle. I'm not sure what causes it but a quick search reveals almost every 6MT car has this at low RPM's and it goes away when you push the clutch in. I've noticed these engines are really shakey at 1700 - 1850 rpm as well.

For the very few others, it could be the shifter linkage, high pressure fuel pump, or loose undercarriage parts (exhaust etc etc). This is quite unlikely, but should still be considered.

Finally, it could be engine knock. There's about a 0.01% chance that's the case though and it would make that noise under load in every gear at low rpm. If you've heard a bad motor in the past, you'd know this in an instant.

I have notice the idle speed varies when I am sitting still for a bit, in neutral. Almost like it is thinking about stalling, but it doesn't.

Something else to check that caused a similar sound in mine is a loose rear axle. The mounting bolts on mine where not properly installed causing them to come loose. Kinda sounded like someone tapping something with a metal hammer but only a few times and went away as soon as I got on the gas.

Finally I found something similar. Mine happens at a little bit higher rpm, light load. Just like a truck...
Lots of people told me it's normal. But it's just annoying because my roommate's frs doesn't make that sound.

Here is my post with videos:

I recently am having a issue with a rattling noise as well but for me it's only on first gear.

Sounds like it's coming from the rear/middle of the car.

if it's the same clanging noise I hear when loading the engine in 2nd gear at low rpm, I've been told it's just resonance of the dual mass flywheel. There's springs in it that have a resonant frequency around 1500 - 1800 rpm in second gear with load on the engine. Engine braking in 2nd gear at low rpm will also make the noise.
