Lexus IS 2014+ :: Downshift Clunk When Coming To A Stop?
Jan 22, 2015
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.

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.

Slight clunk feeling from dead stop under more aggressive acceleration...my 14 250 AWD has done this on 3 or 4 occasions.

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.

I am the new owner of a 2007 Lexus GS350 and I absolutely love the car. 70k miles and it has been well taken care of by the previous two owners. The question I have is regarding a strange subtle jerk when coming to a stop. This seems to be the most intense with a medium force stop but I can also feel it when coasting to a stop. It happens frequently and sometimes is less harsh than other times. I noticed it right after picking up the vehicle but I didn't really pay much attention. After driving the car for 2 months I notice it more. The jerk seems to be happening during downshifting and is at about 15 mph every time. It's not extreme but passengers typically notice it if I point it out. Then they can feel it every time it happens. The other shifts are smooth including accelerating and so forth. I reset the ECU (pulled the ETC and EFI2 Fuses) about two weeks ago but haven't noticed a difference in shifting.

I have been reading some mixed reviews here in regards to the "CLUNK". I am referring to that feeling as if hit from behind shortly after coming to a stop. Some are saying it still exists in the 2005 while others are implying that it has been resolved.
Just to be perfectly clear.... Has experienced this "Clunk" in a 2005 GX?

My 2009 Sonata (4 Cyl.) has begun to downshift very rough while coming to a stop from about 20 mph. At first I thought it was the brakes, but now I'm convinced it's the transmission. Essentially it "jerks" a couple of times before stopping. It started happening at 30,000+ and only happens when transmission is still cold. Once I've driven for a bit it doesn't happen.

I have an intermittent issue where the tiggy seems to downshift harshly to 1st when coming to a stop while in D. Almost like dropping the clutch but not enough to chirp the tires - just enough to feel a thump. I figure it's related to the engine braking "feature" of this car but doing it incorrectly. It seems as though once it's happening, it stays like that for a while, but the next day for example, it will be fine.
I've been observing it for some time now and it doesn't seem temperature specific. In fact, I have a hunch it might be electronic even since if I turn off ESC it stops occurring. Turning off brake auto-hold doesn't make a difference either (this is turned off automatically if ESC is shut off).
I hate taking my car into the dealer for intermittent issues... they are notorious at dismissing something if it doesn't happen right then and there in front of their face. Thought maybe I should check the forums incase their's a TSB or something to fix this exact issue or if it's just unique to my tig.

I have a 2016 is350. I just took off my is250 exhaust and installed it onto the 350. It is an invidia axle back paired with a tsudo midpipe. Since I have made the switch I have noticed several times after braking and coming to a complete stop within a couple seconds the exhaust "pops" usually 1 time and it is fairly loud. This did not happen on the 250. What is concerning to me is that it doesn't sound like normal exhaust popping/gurgling when slowing down or downshifting it is more of a sudden loud single pop after coming to a stop.

I recently just purchased a 2011 Lexus RX350 AWD... I would like to ask on the downshift while slowdown the car.... Every once in a while I feel the tranny down shift while slowing down... It's not harsh or anything, but just enough to have a slight feel. Like a backlash? Is this normal? I also have 09 GS350 AWD.. It's so smooth that I can't feel the downshift at all...

Car that would go clunk after coming to a stop. (don't recall the type of car) It sort of reminds me of what my car will do on occasion. Sometimes after coming to a stop for a few seconds my car's A/C compressor will kick on, kicking up the idle speed of the engine. From time to time I can hear my rear brakes grabbing harder as the car attempts to move forward because of the idle speed increasing. Could be that's what he's hearing also.

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?

2010 F150 XLT FX4 5.4L Crew Cab Medium box, nice blue truck, lacking on chrome though.
My friend has a clunk/lag on take off from a dead stop only. Drives fine down the road, but when taking off from a complete stop, you step on the gas, and nothing happens for a second, feels like it lags, then clunks, gives a jerk, and takes off.
From talking to other newer Ford owners, seems like a common problem.

I've had my truck start making a nice CLUNK from the vicinity of the rear axle when starting moving from a standstill. (and it's a pretty decent thunk sometimes, you hear it AND feel it). I called and made an appt to bring it in and have it checked out (also having the first oil change done and gonna see if they can figure out why the automatic headlights are almost always on even on a bright sunny day) ...

My 2007 Sonata V6 limited would produce a pop / clunk sound (sometimes 2-3 in succession) under these circumstances
- Car is coming to a stop (brake applied)
- When I release my brakes, press on the accelerator, a pop / clunk sound would ensue
It doesn't happen all the time. I noticed it's more prevalent when it's hot outside or when I've driven the car for a little bit
My mechanic re-tightened the subframe bolts and visually checked bushings / ball joints but everything seems tight.

2010 SE 4Motion: My Tiguan's tranny seems to clunk pretty bad when coming to a stop. Wasn't a problem until after I got flashed to APR stage 1 so it may still be adapting, but I'm not sure.

Towing with my 07 F150. I now have a noise all of a sudden. I worry that is the rear end going out. As I accelerate normal from a stop, I , for one feel bump-clunk sensation, as if I have a bad u joint. 2nd I now have a "whip whip whip" whirring sound, sound character speeds up as I speed up.
I hope the sound is the brakes, because I know they are getting down to the end of their life.
