Camry :: 2003 V6 - Trans Makes A Very Noticeable Downshift Clunk On Stop
Oct 28, 2014
I have a 2003 Camry LE with 1MZ engine and U151 5 speed auto trans. 138,000 miles The problem is that the trans makes a very noticeable downshift clunk when stopping.
With light driving you can feel what seems to be a 2-1 downshift just before stopping. With aggressive driving and rapid stop the clunk is felt either when stopping or actually after the wheels stop turning depending on speed and hard braking. If you stop aggressively it actually feels like someone hit you from behind. It literally shakes the car.
TRANS FLUID is full and clean. There is no smell or burnt appearance. The trans tests good in forward and reverse stall tests. Neutral to drive/reverse engagement is also quick and firm.
Here is the fun part. The condition does not exist when cold. After the engine and trans warms up it starts happening. Also, after presenting the condition with a hot trans, I can shift it out of drive and into 3rd and have no problem at all no matter how I drive. To make things more interesting, I can erase the trans learned values with a scan tool and the trans shifts normally for a couple of days before the condition returns.
We are concerned that there may be damage done if this condition continues.

Or just can I just replace and go. I'm having some issues with trans on my 06 gs430. It's having a downshift clunk/jerk when coming to a stop. I just purchased a used trans, but would like to see if it could be ecu related. I have seen other comments from other member that they replaced the trans, but still the issues were present. Some stated that there was some issues with the ecu holding the trans solenoid longer then the usual.

My truck is starting to shift strange. As it warms up and I'm in drive, it will shift between drive and 2nd by itself. When I pull up to a stop lite, it's like it's stuck in drive and doesn't downshift. Ultimately it dies. I've checked my fluid and its fine. Any ideas? Oh and my engine light is on. Can a parts store find the code for the issue I'm having?

1998 accord 4 cyl auto, mostly on start up and when coming to a stop at a light it sounds like someone is under the floorpan hitting it with a hammer. maybe 5 or 6 hits. I've looked into the exhaust being loose and hitting but it's tight and has good clearance. could it be a broken motor mount letting the engine rock too much? next, SOMETIMES when the trans shifts down into low gear you get a very noticeable clunk and the car kind of shudders. planning on doing a trans drain and fill today. lastly the instrument cluster is a little strange. tach doesn't work at all, speedo is fine as is the gas guage but the temp is erratic. when the temp is acting up you can thump it with your finger and it will jump around.

Lexus IS350 ... Noticed a reasonably quiet clunk from the car when coming to a stop? It happens when the transmission automatically shifts into 1st gear with your foot on the brakes.
I noticed that in my car, you can feel a slight lurch forward as the transmission downshifts into first when approaching a stop sign. If I am barely on the brakes, I feel the slight lurch but don't hear anything. Under normal braking, that slight lurch happens along with a clunk. You wouldn't hear it with the radio on, but it's very repeatable and with the windows down you can hear it as well coming from under the car somewhere.

On my 2003 6.0l Excursion, the 5R110 is having some issues with reverse lately. Sometimes when you put it in reverse it doesn't actually engage. The only way to make it "fall" into gear is by giving it a little fuel, which then sends it into reverse. Now here me out, I'm not hitting 3,000rpms when I do this, just a light raise in rpms will get it in gear. Solenoid issue, possibly?
I haven't noticed if it does this when it won't go into reverse or if it does it no matter what, but it will make a light clunk when going forward after using reverse. A very light, but noticeable clunk. Is this most likely a U-Joint related issue? Got under it and moved the driveshaft around, didn't notice any play at all, but perhaps I wasn't checking properly (wiggling it left and right).
Excursion is RWD (2WD) and has right around 183k miles on it, acquired in October with 172k miles, so not positive on previous history of the transmission. Also I know my gear selector mount is broke, so it cluster is off, but I certainly don't think that, in of itself, is the cause of my issues. Maybe I'm wrong?

My 2001 4.6L F-150 has been sitting on the driveway, used once every 2 weeks or so for the last 3 yrs. I came to start it a few days ago and it kept turning over but not starting. The key security chip is working, battery is charged, all plugs are firing, fuel pump fuse and relay check good. When I turn the key to ON, sometimes I hear the fuel pump priming, other times it doesn't. The times it does prime, the truck fires right up.
The times it doesn't prime, engine won't start. When the pump does prime, and while the engine is running, the pump makes a noticeable buzzing sound, much louder than normal. When the pump primes. fuel pressure measures at 42psi in the ON position, 36psi with engine running, and 46psi with engine running and vacuum hose removed. I believe all these are within specs.
My question is this: Is it safe to assume that the pump is going bad and will eventually fail completely? My second question is (and I know this can be debated til the end of time) should I get the Motorcraft or aftermarket? I have Airtex, Spectra, Carter, and Delphi available locally.

I have a code P1740 that sets after a couple of drive cycles. This is preceeded by a flashing "Overdrive Off" light, until the MIL eventually comes on.
The only driveability symptom seems to be a premature downshift into first when slowing down. When cruising at highway speeds, I can turn OD on or off using the switch on the end of the shift lever and all appears OK.
Could it be the OD solenoid, and if so is this something I could change myself?

The subject: F150, 2007, 5.4L, FX4 version. It has only 80K miles and was very light used by my sister. It seems to me come with a 4R75E ....
Recently I notice a strange vibration every time tranny downshift from 4 to 3, specially noticeable going uphill. Some times can be feel when tranny shift from 3 to 4th...
A friend in my town comment to us, this is a very common condition here because there are just small streets and avenues so that truck shift very frequently betwen 4 to 3 and then back to 4th...
Sounds like a excessive wear on a bearing thrust ??

When the driver side door is opened there is a clunk sound about half way through the swing. When the door is closed there is a couple clunks then a thud. The sound is coming from the front of the door.
What is causing this and does it mean big trouble soon?

My 2012 V6 seems overly susceptible to the belts squealing (which leads to the AC not cooling until the belts dry) when I drive through a puddle.
I don't have charging or electrical problems or any symptoms of a too loose belt, although I suppose perhaps it is slightly loose? Or is this just a common problem because of a not big enough splash guard?
I'm not talking about driving through a monsoon flood with water up to the doorjams, I'm talking about even going 5 to 10 or 20 mph, through a dip in the road with a little standing water, and knowing water will splash up into the engine compartment, make my belts squeal, and half the time, make the AC stop until the belts dry.

So I keep hearing about how the DSG makes a unique sound when you manually downshift.

My 2007 Santa Fe with 48K km developed a clunk in the front end that was most noticeable when traveling under 30 km/h. I made an appointment with West Edmonton Hyundai. This was not the dealer I purchased the vehicle from as I moved to Edmonton after I purchased the vehicle. The dealer had it fixed up within 3 hours....both sway bar end links were worn out. Just wanted to point out the good service I got. The entire bill was covered under the standard vehicle warranty.

I don't do too much long range driving but i notice about a week ago i was driving about 70mph for about 40 to 50 miles.. and when i got of at the exit i started to slow the car down and during the down shift i felt the car to a little jerk and clunk with a bit of hesitation during it.. Today i was doing another long trip and it did the same thing..
i use the highway a lot but usually on it for maybe 5 to 10 miles and it never does it.. I called the dealer and explained it to them and he said he would have to drive the car. and i know since it only happens on 40 plus mile trips the dealer isn't going to go for a test drive that long..
The next long trip i have might be tomorrow nite headed to AC for some gambling so i am going to try to remember to bring my camcorder so i can try to record it for the dealer..
car is a 07 wolfsburg 2.0t automatic completely stock..

My 3.6 4motion has a rough downshift, 4th to 3rd. I can feel the clunk. The service department (which has been otherwise great, at Gurley Leep in South Bend, IN) says it's "within specs." And no TSB. I know we've discussed the TSB for the rough downshift on the 2.0T. Anything on the 3.6 4motion?

I have a clunking sound coming from the back end. It is most noticeable at lower speeds going over bumps. I can also make the clunk happen by grabbing the top of the right rear tire and rocking it. I can feel something moving while I am doing this, but I can't pinpoint it. The bushings seem to be in good condition. The left rear wheel bearing was replaced recently. I also have an intermittent brake pulsation which feels like a warped rotor. I don't think it is actually the rotor, because it doesn't happen every time I apply the brakes. I believe that these two things are related. Is it possible for the rear struts to cause these issues?

2011 Sonata Limited ... I have just under 60k miles and did a tranny drain and refill at 24k and 55k. Just had the brake light switch replaced. For some reason when cruising with the car in overdrive, if I let off the gas to decelerate and ease into the gas again, I get a real hard down shift and shift. So every time I get on the gas again it is either kicking out of overdrive or downshifting and shifting back immediately. 99% of the time it is a hard thump. When I have the cruise set I do not notice this at all. It does it in ECO or out of ECO. This is new and I started noticing this after the brake switch replacement.

I'm getting a CLUNK when coming to a stop with my truck.
If I shut off the overdrive while coming to a stop it doesn't do it. Or if I manually shift it down a gear.
I read on here it could be a U-joint or the yoke or something and maybe something needs greased.
Anyway I crawled under the truck and it looks like I need a special socket to remove the 4 bolts holding the driveshaft to the rear end.
What type of socket it this? No grease fittings on my U-joints. What's causing this CLUNK as well?

After braking down to 15 or 20 mph my 2004 Trailblazer transmission has a slight hesitation and clunks when I start to give it the gas. Could this be due to a sticking modulator or some other issue?

Recently started experiencing a hard downshift after driving for 30 minutes, and only from 2nd to 1st. No other shift issues with other gears, up or down.
When moving over to manual shifting, it doesn't appear to have the issue when downshifting in manual.
I replaced the radiator about 2 weeks ago due to a serious leak, and the shifting problem wasn't an issue before as I would have noticed.
Going to start with the fluid lvl, but it feels odds with it occurring during the downshift to 1st.

I was driving up a fairly big hill in Connecticut using cruise control (65 mph). The transmission downshifted, and the car started to rev (speedometer and tachometer) and slow down. I then felt a clunk and the car started to go again. The car kept on doing the rev up and then clunk as it gradually slowed down. Putting the car in Park caused a grinding noise, and Park did not keep the car from rolling. What did I break?
