Lexus LS 2007+ :: Latest TSB Shuddering Transmission At 30 - 75 MPH?
Sep 10, 2012
Those with AWD model LS's and shuddering transmissions. Don't go into the dealership barking orders. Just mention that you "think" your car is suffering from this condition and that you would like it checked. Certain conditions have to be met with the vehicle so plan on leaving it with the dealer for the day if possible. It has to be driven with the scan tool connected and recording live data. So this is NOT something you want to drop-in unannounced for.

2005 GX470 transmission shuddering. While lightly driving, I feel a shudder at approx 35 mph, then again at 45 mph. I took it to the local Lexus dealer to have them analyze. Would you believe I could not get it to shudder when the mechanic went for a ride-along. Meanwhile, I'll just wait until the problem gets worse then bring it back in.
The mechanic mentioned Lexus had problems with the LX a few years back with transmission shuddering, but not with the GX.

I have a new-to-me 2008 LS600hl I recently purchased with just over 60k miles. When I test drove the car I noticed some vibration that the dealer and I presumed to be tires or even warped rotors, however after a balance and resurface (they paid for) the problem persisted. I then set out to isolate it further my getting up to 60mph and letting the car coast down to 35 several times. There is a very pronounced shudder in the driveline- almost like a washboard road effect, most noticeably as it drops through the 40's mph. I can completely eliminate this if I drop the drivetrain in neutral- therefor it has to be in regeneration or the transmission.
That said, the dealer had a Lexus engineer look at it. His assessment was uncertain, as there are no other LS600's around to compare it too. They would like the problem to be more pronounced so that they can be sure where the problem is coming from and asked me to drive it an additional 5000 miles.
The mechanic and service tech agree with me there is a problem, but are now somewhat bound by their engineer telling them to wait 5000 miles. I'd really like to have something else to support my claim. The car has a week of warranty left on the drivetrain when I purchased it- so the problem is documented.

I'm a proud owner of 2005 Mustang GT, 4.6L with an automatic transmission. Intermittently for the last year or so (maybe once every 3 or 4 months) its been shuddering when in reverse. Today it ramped things up a notch. :-/ The shuddering was pretty dramatic when I was trying to back out of my driveway, I shifted into park for a moment, then back into reverse, and it seemed to be ok. Then when trying to back into a parking spot this afternoon at work (in a parking garage with a small incline) it lost power almost entirely in reverse, lightly pushing on the gas just caused the car to shudder and not move anywhere. I shifted into park, and then back into reverse and heard an audible "pop" (my windows were down, but they hadn't been earlier so I'm not sure if this happened in the morning) and the car did not want to reverse. Rather than risk further damage I decided that it was parked relatively ok (90% in the space, eh good enough) so I stopped.

Working on a 2002 prius with 153k miles. bought it with a "Bad transmission" diagnosed by toyota dealer. Got I home and did a quick check but there were no codes. I drove it about 50 feet into my garage where it would shudder badly while being driven which from my experience sounds like a bad MG2 motor. Drained the oil and thought hhmmm th oil does not smell bad and neither did it look burned. Proceeded to pull the mg2 but found it looked brand new, no burned spots or any such thing. SO I put it back together and think its a bad invertor. put on a different invertor that I have lying in my garage that I "think" is good and start the car. get code p3125 and p3120 and still have the bad shuddering when i try to drive it..Is there any way to test it further before I pull the trans and put a new trans back in?

I have a 2002 F150 Super crew with a 5.4 and a 4R70W tranny. The issue I am experiencing is when the truck is driven where the tranny has shifted through all it's gears and cruising at say 55 mph, when depressing the accelerator pedal it either downshifts of something unlocks making a shuddering sound which sounds like when you run over rumble strips on the side of the road. The shuddering only happens for maybe a second at the most. If I am on the accelerator pedal when it up shifts or locks back up it makes the shuddering sound again. The harder the unlocking / locking or downshifting / up shifting happens the harder and longer the shuddering is.
This shuddering happens at the very last transmission function which happens in the transmission during it's normal operation. Other tan this issue the tranny shifts and operates excellent.

The problem is that it appears the torque converter is locking up so early even right after getting into second gear at speeds between 20km/h and 40km/h. This causes shuddering/rattling coming from under the hood. If I am not mistaken a torque converter should lock up at speeds 80km/h+. I've never seen this behavior on any car before. I'm not sure what kind of damage is being done either by all this shuddering and rattling going on with the transmission. I feel that this should be something that needs to be addressed via some software update. Is there any software update in regards to this issue?

I bought a 2011 Santa Fe in September and now that winter has set in up here, I find that when approaching a stop sign and there is black ice, I noticed that when you press on the brakes, it shudders. Almost jumps if you know what I mean. I've never had this experience and scared the crap out of me the first time. Is it normal? The only time it does this is when the wheels lock and slide on the ice. The brakes? I think then shudder. This is the first Hyundai I've ever owned and love it so far.

2007 Camry LE. This morning while driving, she noticed a shuddering that scared her. She called me and parked the car as soon as she could. I went to drive it around and, as she had said, it was shuddering.
I drove it for a bit, neighborhood and highways, and took note of everything. The RPMs were low - About 500. I'm not sure where it usually idles, I rarely drive this car, but my Jetta idles around 900 so this seems strange to me. RPM gauge occasionally bounces around at idle. Once the car gets moving there are no issues. Only at complete stop. It feels like the car is about to stall.
I drive a manual and if I keep it in gear while approaching a stop it makes the same shuddering because the RPMs are too low for the selected gear. This is what it reminds me of.
Here is a video of what's going on under the hood. As you can see, the airbox is vibrating heavily. That's the most obvious place. The engine and intake manifold are also bouncing around, but it's hard to see in the iPhone video.

I just bought a used 2007 Santa Fe Limited. It has 78,000 miles on it. I have gone bumper to bumper looking for problems and am pretty happy about the condition. HOWEVER, I have noticed a shuddering/bobbling, fairly faint, when going over slightly rough roads a low speeds. The tires are shot. But they are all exactly the same ... meaning the same wear more so on the outside. I believe they were rotated properly, but something is wearing the outside prematurely. Is the shuddering/bobbling the culprit? What is the most common issue for the Shuddering/bobbling at low speeds on slightly rough roads?
Next, I want a quiet ride. Handling is not a concern. Should I go with a slightly wider tire or slightly taller tire? Lastly, I need new mats. I want them to be the same as what came with the car. Do I have to go to the dealer or are there some vendors with better deals on factory mats.

2007 LS460. On a couple of occasions recently, my transmission would not come out of park. I shut the engine down and restarted and it worked fine. Is this a sign of bad things to come?

I have a 2007 Honda Element. When I am driving at slower speeds (<20mph) and turn sharply the vehicle shudders very hard. What is causing this?

I purchased my first Lexus in October, a very clean 2009 ls460. In colder weather (for Tucson AZ) in the 30's to 40's I notice that the transmission slips while the car is accelerating between 2nd and third gear.
By slipping, I mean as the car shifts between 2nd and 3rd it feels like it goes into neutral for a half second, so rpms spike 500 rpm, the car stops accellerating, and then catches as the next gear is finally engaged.
It does this pretty much every day when the car has been sitting overnight on the first steady acceleration after backing out of the garage. It only does it once, subsequent shifts a re pretty much normal.
Every once in a while coming out of a parking lot after say grocery shopping, it will do it again, just once.
I dropped it at the dealer and they of course could not replicate it.
I made a youtube video which shows it sort of. besides the rise in engine rpm, you feel a lurch in the acceleration as it drops down into gear.
Service records showed the trans was serviced just before I bought it.

I purchased a 2007 ES350 from a Toyota Dealership (64K, now has 66K). I purchased a warranty for the vehicle. Over the last couple weeks I have begun to notice my transmission is slipping - the car will rev up with no acceleration. It will usually catch on the second attempt of pressing the gas pedal. I notice this behavior usually after a cold start in the morning as I am leaving for work.
Before I go into the dealership to tell them about my potentially expensive problem, I want to ensure I go in knowing as much as possible. I have already found a ton of issues surrounding various transmission flairs at varying gears. (TSIB: TC001-06)

I have recently purchased a 2007 Lexus and just starting having a problem when trying to accelerate when I first start to car and try to move forward.
Basically I put the car in drive accelerate, the RPM is high but the car moves at a snails pace of at all.

For the first mile or so on cold mornings, by transmission shifts slowly - sort of a second or two delay until the car warms up. Is this normal?

Many people speaking of the flare they get; up to 1000 rpm between 3rd and 4th gear when the car is cold.Here's what I did.
Started the car. Cold as normal. Let it warm up "NORMAL". Meaning NOT for 5 minutes or anything. Just the normal 30-60 seconds like most people do first thing in the morning. Before pulling away and driving off, I took the transmission and ran it through the gauntlet.
Park to reverse:
Reverse to Neutral:
Neutral to Drive:
Drive to Manual: (Automatically starts in "4")
Manual tap down to 3, 2, then 1.
Manual tap up to 2, 3, 4, 5, then 6
Manual back to Drive.
Take it back to Park:
This whole process took about 10 seconds. I then pulled away and drove off. Temperature gauge still hadn't really moved. Total time since starting the car is probably only about 1 minute or a little more. While not spinning tires, I did accelerate "Faster than normal" just to see how 3rd to 4th would go. There was no flare at all from 3rd to 4th.

I have a 2009 that seems to have issues in the lower gears, I think that I have a transmission issue.
When I'm coming to a stop, I feel the transmission downshifting from about gear 3. It's not wildly jerky or abrasive, but it's not smooth either (or I wouldn't feel it). When it downshifts, after it engages (or torques down for lack of a better term) it feels as if it releases a bit, which makes me have to compensate with harder braking (again, not saying I am slamming on the brakes, but I have to brake harder so it doesn't feel like I am now going to coast into the car in front of me). It doesn't feel like the transmission is going to take off on its own, but it definitely feels like it has a certain threshold it wants to stay above.
In the loaner I have (RX), when coming to a stop the best way I can describe it is it feels like the transmission has completely disengaged and I feel NO transmission downshifting at all. The only way I get this type of braking in my LS is if I throw it into Neutral and take the transmission out of the loop. On the way to the dealership this morning to drop it off for other issues, I was at a stop light and went to accelerate and it felt as if it skipped a gear because I was stalled for a second (acceleration wise, not that the engine turned off) before it took off as it should. Also my acceleration seems to be a little hesitant when starting off .

I have sent my 2008 ES350, 47K to a dealer since it has a bit hesitation on accelerating; RPM goes upto 3K easily to get engaged to next one.
The dealer told me that no hardware problem but they did update a tranny firmware. They added that it may work right away or work after 3~4 fuelings.
What would be next step?

I recently bought 2007 ES 350 drove @700+ miles, 2 times I had this incident in this week, the latest is today. In cold morning when I try to drive the vehicle when it is cold when I pull the lever to drive mode the accelerator increases the RPM but the car is not rolling or I should say very very snail pace, so I tried pushing the lever back to park, then reverse drive the vehicle and then engage to drive mode it works fine but I hear lot of fan sound. For initial few min I feel that it is not picking up much speed but then it becomes normal. It really tensed me. What action can be taken to resolve this?
As per the Autocheck report this was manufactured in Jun 2006 and the vehicle service records from Lexus web there is no sign of any transmission problem or fix to transmission. The car has 100K+ miles on it.

Lately I have noticed that the transmission is not shifting smoothly in the lower gears. I have 114K on there. Spoke to my service manager and he mentioned that it may need calibration. Doesn't sound right after all the miles?
