Today (not 2 days after taking delivery) I was travelling on the highway. stopped for fuel and as I am decelerating on the offramp when the truck shifted from 5th to 4th it went CLUNK, It did this twice, in the same circumstance. I can't make it replicate the noise every time. But 2 times in 24 hours is enough.
View 10 RepliesI have a 2005 Accent GL (4dr Sedan) base model, 5 speed. I live in Canada (not sure if that will play a part); I notice that when I shift from first to second there is a 'clunk', not really a grind, and not a major clunk... but it's noticeable. As the car warms-up, it seems to be less pronounced (or maybe I start to ignore it). Is this something to worry about? or could it be the clutch plates.
I have had lots of bikes with wet clutches and this is 'normal' for a bike going into first gear. With the bike it's due to what I call Hydrolic-stick ... (2 or more) plates 'sticking' when you let the clutch out, one spinning faster than the other. Off topic now...
2007 Azera 120k miles. Have noticed first thing in the morning when shifting from 4th to 5th gear, I hear a clunk.. Yesterday I heard two clunks when downshifting from 5th to 4th. Tried shifting the car manually today and was able to replicate the problem. After 15 minutes of driving, the problem is gone.Never seems to happen in the afternoon after car has been driven.Transmission fluid is full. Have always changed at the 60k intervals.Fluid is not burnt. Light pink color.
What could possibly be causing this? Is this likely to get worse? How long might I have before the car might become not drivable ? I ask this because I have been considering trading it in for a new car. Now seems to be a good time to buy a 2016 car, since the 2017"s are almost out.
I have been reluctant to post another clunking thread because it's nearly impossible to accurately describe what is happening. But I have reached by breaking point and I wanted a few opinions before I take it into the dealer. I am still under powertrain warranty, but I want to be confident I am not wasting mine and the dealers time if I am just missing something easy. I also know dealers don't always take clunks seriously so I want to pinpoint it first.
Symptoms : Car has 50k miles. I am the original owner.
From a stop, when getting the car rolling moderately aggressively there is a clunk/pop noise from the car. I can slightly feel it in the pedals and it is fairly loud. Almost like a distant hammer and nail pounding. It's a single clunk, with sometimes a double "pop pop". It's noticeable even with the radio turned up a little. If you are smooth on the throttle it doesn't make the noise. It seems random, like something is hitting something which only happens under certain weight shifts.
It sounds like it's from the rear and the front. It seems to switch. But honestly I am not confident either way. Where it is. It is silent on turns, bumps, speed bumps, driveway, etc. I don't think it's the suspension. It is not a clicking/tapping, only a single clunk or knock.
It also happens in 1st/2nd in stop and go traffic. If you leave it in 1st and the traffic is moving from say 8-15mph where you don't need to use the clutch it will clunk during on/off throttle. Anything above ~30mph I haven't been able to replicate the noise with on/off throttle.
It also does it if I downshift when coming to a stop and don't rev match. Say you are slowing down and you go from 4th, 3rd, then 2nd, let the clutch out and it rev matches up to ~3,000rpm which causes the weight to shift forward....clunk! It is not easy to replicate which is another reason I am slow to bring it to the dealer until I pinpoint it.
Things I have tried:
- Subframe bolt torque check. Installed ECS spacer/bolt kit anyway.
- Sway bar links are tight, or at least they didn't budge at all.
- Adjusted the rear hatch a million different ways as it was making a similar noise earlier.
- Spare tire tightened, tools removed
- Rear seats up/down/mix/seat belts fastened, etc.
I was only able to locate one motor mount? Where they are. Seems fine. Dogbone seems fine, again hard to tell.
Suspect:
I have VWR springs, but I am 90% sure this started happening right before I had them installed. I did the rears myself, a well known shop did the front. I noticed the noise maybe 2k before the springs were installed.
Clutch linkage somewhere - I had issues with my transmission (early build). The clutch was replaced at 7k. I've always had a very loud flywheel and a grinding feeling in the pedal. Maybe the shifter linkage is hitting something? I have little experience with VW's so I am still learning and don't know what to check.
My rear harmonic balancer is cracking like everyone else. I have no vibrations yet and I don't see how it could be causing a clunk in the current state. Maybe a motor mount is bad that I cant see? It feels like something is loose in the drivetrain.
Sometimes when putting the vehicle into first it's almost impossible to get it to go into gear. Sometimes it's super smooth. Also when putting into reverse we hear a loud clunk. That one is most of the time but sometimes it goes in smooth. I was doing some looking around at the pedals because I think I am going to have to replace my master cylinder and noticed that on the inside of the vehicle where the clutch master cylinder comes into the vehicle it's leaking black fluid. Does that automatically mean my clutch master cylinder needs to be changed? Could this be the cause of it being difficult to shift because the clutch isn't fully disengaging?
View 11 RepliesTurns out the brains of the transmission are not working. Valve body to be replaced under warranty. We were getting severe Clunk between 4and 5 gear and 5/6. It was more pronounced going up hill and when towing. Actually scared me a few times with severity of the noise and shudder of the vehicle. Will take a week for parts and warranty work to be done. I assume it is a very expensive undertaking.
View 2 RepliesWhilst driving unloaded, I mean the car is not under load, in say 5th gear , if I go to increase acceleration I often get a sudden unsmooth change to 4th. The change is not the normal smooth change down but a very abrupt clunk back to the lower gear. This is intermittent and hard to demonstrate to the dealer for repair.
View 4 RepliesNew truck 11000kms ago thats done medium amount of work but nothing heavy or sustained for long periods of time. I get the feeling of clutches slipping especially when truck is cold but also when normal temps. Doesnt make any weird noises or anything. I can really notice the difference in torque if in manual mode being much better, but still not perfect if i stomp on the gas pedal and go through the gears in manual mode will still slip. Also is really harsh shift if i come to a halt in 3rd manual mode with the brake pedal depressed push minus button the truck makes very loud clunk noise into gear 2 then 1. Took it to ford they couldnt find anything ? Thinking of trying another dealer.
View 2 RepliesI am hearing a noise first thing in the morning when I leave my house and the car is shifting from 2nd to 3rd. The sound, I think, is coming from the front center of car, say directly below the radio area. The noise lasts only 1 to 2 seconds and sounds like when some tries to put a transmission in reverse while still rolling forward. A metal against metal sound of two pieces trying to mate up. I'm thinking transmission...I'm hoping center diff. There was mention of a scraching sound coming from front passenger side on initial startup. Idea was this could be Immobilizer or ABS.
View 2 RepliesI am new to the all wheel drive breed. When I turn the all wheel drive knob one click over to the right (4x4 low I believe) how much rougher should the shifting be. I notice it starts in 2nd gear, but 2-3 shift jolts the car to the point it almost snaps your neck(not WOT just normal accelaration). Each subsequent shift is a little smoother, but still very noticably rough. Is this normal? Even in the regular high mode, sometimes my regular around town low throttle shifts are pretty jolting.
View 4 RepliesSeems like the problems just keep building up. Today leaving work T-reg shifts fine untill it got to 5th gear. It was around 35 mph. Went to give it more gas and it never shifted out of 5th to a lower gear. It did accelerate but even with pedal to the floor it never downshifted. Whats going on. It has done it twice in the past two days. After only having it on the road for less than 5 min each time.
View 6 RepliesOccasional clunk when truck is shifting gears. Not consistent. On highway at high acceleration clunk is more apparent. Any thoughts. 2004 v10 with new engine placed at 70,000km now at 85000km. Otherwise truck is running great.
View 8 RepliesExperienced a clunk when shifting from D to R, especially when in a parking situation where you might shift back and forth a few times. I always make sure the car is not rolling and my foot is firmly on the brake while shifting from D to R or vise versa, but it doesn't seem to work. Is this normal with the DSG or should i bring it in to the dealer?
View 11 Replies"Clunk" noise when shifting from P or R to D happening to me right now with my '06 GS300. It doesn't happen all the time, but it happened all day yesterday and sounded pretty serious. Took it into the dealer today, still under warranty, and of course it wasn't happening. Tech said he will keep it overnight, let it cool down, and check transmission fluid level which could be the issue. If that isn't the issue they said it could just be a "normal" sound. My wifes 2006 Sequoia shifts smoother and doesn't make a sound when you go from P or R to D ... Don't tell me it is the break pads releasing either because that is just as far fetched as the normal theory.
View 14 RepliesI've just bought a 2005 Prius, 142k miles. It's a great car, and frankly with any 'new' car I buy I always worry about new sounds. This time it's 'clunk' or 'thump' noise when shifting from D to R and vice versa. It doesn't happen all the time, but it's a noticeable noise that can be felt as well.
View 7 RepliesI own a 1994 Mazda B2300/Ford Ranger. Ever since I have owned it, there has been a slight "thump" when you let off the accelerator. Annoying, but for a cheap truck, I just ignored it. NOW, there is a clunk when I lift off, and when I hit the accelerator after shifting gears. There has been a loud "rumble" sort of sound for about two weeks, and I was told by a mechanic that I needed a "cat back" exhaust. Okay, but when I rev the truck in the driveway, it doesn't sound like the exhaust has issues. I DO get the rumble through the steering wheel and floor of the truck, and up until this morning, when I took the thing out of gear, or stepped on the clutch, the rumble sort of went away. Now, it doesn't.
View 4 RepliesI own an automatic 2009 Accent. I'm at 95,000KM.
Anyway, the problem does not occur all the time and appears to be entirely random.
When I start my car, on occasion, the car will make a CLUNK sound when shifting from park to reverse or drive. When it does CLUNK, you can feel the car lurch as if something fell out of place. The sound is quite audible, even with the radio on. The sound and lurch is not as pronounced when shifting to reverse. It doesn't seem to happen when going to neutral but is very obvious when going to drive.
Turning off the engine and restarting it seems to resolve the issue. Once I had to restart the engine twice before the clunk stopped.
Attempting to drive when the car does this sound results in increased RPMS. Usually when driving the RPMS sit between 2000 and 3000 but would jump to between 3000 and 4000 when the clunk occurs. Usually, the car will want to crawl forward if I'm not on the brakes but with the clunk, the car need quite some gas to start going forward.
Here's where it gets scary:
On two occasions, while driving on the highway at 100km (65 miles), I'd feel something slip and then suddenly my RPMS jump up by 1000. On both occasions I had to pull over, turn off engine and restart the car and the issue stopped.
Clearly, whatever it is that changes gears is slipping but the fact that it slips while driving just freaks me out.
The first thing is that suddenly there's a clunk type noise from the transmission when shifting in to or out of 2/3/4. Also, when I'm in one of those gears, letting off the throttle and then re-applying lightly causes the clunk noise. However, I haven't noticed any actual performance difference, just the new noise. It's loud enough that I can hear it over the radio at a reasonable volume, and it may or may not be my imagination but I think I can feel it through the floor of the car.
The next thing is that in the mornings, the car seems to have trouble getting in to gear from a stop. So I'll pull up to a light, then stop, and if I take off the brake and get immediately on the throttle, the car will lurch pretty bad, even if it's only a little throttle. I've found that if I let off the brake, and wait specifically to hear/feel the transmission kick in, there's no lurch and everything is fine.
Also, on that same note, sometimes when I let off the brake at these times, the car nearly stalls. It hasn't stalled yet but it's felt close a few times.
As well, from a cold start, there is what feels like an absolute ton of engine braking in second gear, I can feel the car pulling back immediately after I let off the throttle, and this seems strange and new as well.
My 2006 Elantra (54,000 miles) shifts really, really hard when it's not cold and passes through the 35 mph range -- hard enough to make you glad you've got your seatbelt on. I've taken it to my regular mechanic and now it's in an automatic transmission shop.
My mechanic changed the fluid (twice), and took it through a "learning sequence". The fluid didn't look that bad and he reported that there were no codes to work with. He thinks I'm going to have to get a new transmission.
The AT shop has confirmed that there are no codes to work with and that the problem begins at 143 degrees. They tell me that the transmission is shifting into a higher gear without releasing the lower gear. They tried replacing a couple of solenoids, but that yielded no change in behavior. Now, they're telling me they "think" I need a new computer. I'm just afraid the trial & error approach is going to cost me a boat-load.
I just had the motor torque and strut mount fixed and was told that I have an exhaust leak flex pipe. My problem is I'm still getting a clunk when shifting into reverse doesn't happen all the time but it is concerning plan to have flexpipe fixed in the near future. will that take care of the clunking sound or is it something else? don't have a lot of cash to work with right now.
View 1 RepliesI have a 93 ford escort which makes a clunking noise if I shift into reverse without letting the car warm up and idle down. It sounds as if the noise is coming from the front passenger side wheel well. The sound does not occur when shifting into reverse if the car is allowed to warm up and idle down to 1100 rpm. What's up?
