I'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 RepliesMy boyfriend bought a 1999 ford explorer, he put about 2,000 miles on it in four months... I believe it now has roughly 110,000... Now the other day, he was pulling out and shifted from reverse to drive, we heard like a loud clunk/thump noise... It shifts into drive, and revs but won't move, it feels like neutral... If you shift to second, first, or reverse it's fine... Tranny fluid is good... O/D is always engaged...
View 3 RepliesOverall, my wife and I like the car. It feels solid, and so far we have about 950 miles on it. Today though, something weird happened.
I was driving, and we were getting on the freeway after crossing an overpass, so it the on-ramp was one of those sweeping, downhill, 270 degree curves to the right. Nothing out of the ordinary.
So I let off the gas, and I'm taking the turn, and there was this "thump!" noise - almost as though the transmission was shifting. The car shuddered. Then it did it again.
It was disconcerting, almost reminiscent of our wacky dual-clutch transmission issues we had with our 2011 Ford Fiesta. Now granted, its a bit of conjecture since I don't know what could have caused it. I wasn't going quickly enough where any stability control mechanism (ESC) should have kicked in... so I'm not sure what else could have caused it. Undoubtedly I'll be testing it again to see if I can reproduce it, but its got me concerned.
I 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.
I have a '74 Dodge B-100 van, 318 V-8, with a 3-speed A727 TorqueFlite tranmission (which was totally rebuilt about 20,000 miles ago). Overall, this old baby that we call "Blue Thunder" is in almost pristine condition. It starts well, runs great, and over the years has been highly reliable. It's been in the family for almost 38 years and is special to all of us. I've maintained it extremely well from day one.
Here is the big problem.....under very light acceleration at the 2-3 upshift, it makes a loud-sounding and aggressive-feeling "clunk" or heavy sounding "thump". Under hard acceleration, or accelerating on an upgrade (hill), it does not make this sound at all and I do not feel or hear it at all. There are no other accompanying symptoms such as whines, roars or vibrations. I recently took it to a reputable (in business for 35 years) transmission shop recently with the above problem description. He checked the fluid and adjusted the kickdown band. This same shop had serviced the transmission a year earlier. He recommended that I let him him take it to a general auto repair shop down down the street for a diagnosis on the "loud clunk" ....as he did not think it was a transmission problem.
I agreed for him to do so since, the shop "down the street" is also known for quality repair work. The written problem description was sent aong with the van. In a week or so, the auto repair shop called and said all they could find was a little wear in the spider gears in the rear differential. I gave them permission, since the differential was already open. to replace anything that looked like it needed to be replaced. It took a while to get the parts, but they replaced the spider gears, both side bearing cups, and 1 of the differential bearing adjusters. Of course the work included new gear oil and gasket for the differential cover. It was an onerous bill, but I didn't complain, thinking that the terrible "clunk" would be gone. I picked up the van and immediately noticed no difference at all. The loud "clunk" was still there under the exact same conditions.
I took it back and asked the owner to ride with me where upon I easily recreated the "clunk" by accelerating very lightly. He said, "Oh, that's in the transmission, because it's only makes the sound when it shifts from 2nd to 3rd gear". I called the transmission shop back and they want nothing to do with it....saying that a noise like that one is practically impossible to pinpoint. He said even if the transmission were rebuilt, he cannot guarantee the noise would not be there. Both shops say the U-joints, yokes, engine mounts, and transmission mount all look OK.
I have a 2002 Camry, and recently on the passenger side towards the front wheel there has been a fairly persistent thump or clunk when I brake at low speeds (i.e. immediately before a full stop). I took it to my local mechanic yesterday to see if he could figure it out, and unfortunately he wasn't, although he did point out that my dog bone was cracked and suggested changing that out. Afterwards, the thump/clunk did seem to be more subdued, but it's still obviously there.
View 12 RepliesOur excursion usually sits unless we are towing or need to haul a group of people. The past three days my wife has been using it as a commuter. Yesterday she told me that two times at start-up she has heard a loud clunk/thump sound coming from the rear of the vehicle. At first she thought it was happening when she engaged the brake to put it in drive. Today she called me and told me the sound came just after start-up while the vehicle was warming up before the brake was applied. What this could be? I wish I would have observed it so I could give more details.
View 2 RepliesI get this thumping noise during shifting at times. It doesn't always happen but I hear it somewhat frequently. It's a deep thump coming from the transmission during shift.
View 6 RepliesI've been hearing a quiet 'thump' when shifting. In particular, when first letting up the clutch starting out in 1 but also when shifting between gears when the clutch is fully down such as from 2->3.
I thought perhaps a fluid change was in order since I'm at 110,000 miles. It didn't make any difference. (I used Mobil 1 GL5 which according to independent tests is safe on yellow metals.)
So then I wondered if it's the engine mounts, but I'm not sure what it sounds like when they need to be replaced or if simply shifting between gears while driving as described above would cause a worn one to 'thump'.
My new 2012 Prius III was braking with the normal Prius noises until yesterday. It as 1,000 miles on it and while my wife was driving it on the highway a person cut in front of her so she had to brake hard to avoid them. Ever since then when I press on then brake normally I hear a thump noise and feel a vibration under my right foot (just to the left of the brake and on the floor). It comes when I brake at speeds greater than about 12 mph. What it is and why it started? I'm planning on taking it in to the dealer to get it checked out...
View 11 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 RepliesRecently my 2004 Santa Fe 2.7 AWD (~86k miles) has started to give a sort of hard thump when shifting from reverse into drive. It's fine going into any other gears and it shifts up and down normally. If I shift from reverse to neutral and then to drive it's fine.
I changed the transmission fluid when we first got the car at 40K miles with Hyundai Liquid Unobtanium SPiii fluid and again at 80k miles with Valvoline's SPiii offering. I just checked the transmission fluid level and it's within the normal range.
I can't tell if this is just drive-line slop or something else inside the tranny.
Last year, July, replaced Trans.modulator..All went well. Now..sloppy shifting, occasion heavy thump changing gears when slowing. Trans. people say All good according to their programs.....but they also feel the same problems. Its an internal problem, they say, too expensive to tear down.Drive it until it dies. ( 161 K on the odometer.....otherwise is perfect. I want to do a flush, then drop the pan, change the screens, tighten the bands and replace Trans. fluid.
View 1 RepliesO.K. first of all I had an issue with the Odometer pointer being jumpy. Sometimes it wouldn't move. Now I replaced the input sensor at first and did not fix the problem. I replaced the output sensor and fixed it. "BUT", Now, I have a problem with the transmission shifting. I get an engine light while driving and the 2nd gear seems to take its time shifting and when it does it make the left side drive shaft kick in hard and spends my wheel to a screeching effect. Plus a thump on the transmission. I rechecked the sensor for connection and reinstalled. Drove the car still have the same issue?
View 2 RepliesToday (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 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 RepliesOver the last few months I've noticed a clunking/rattling in the front end somewhere -- probably started at around 60,000 miles. I've considered T-SB-0300-08, but it can range from a clunk-noise to a metallic clunk-noise, and is often felt on smallish bumps. Sometimes I can feel a knock in the steering wheel, especially at very low speeds. I get the distinct feeling that the front wheels might be wobbling a bit as things clunk going over small bumps. Predominantly a left-side thing, but not exclusively.
View 19 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 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...
I 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.
