Lexus GX 2004-09 :: Rumbling Vibration When Transmission Shifted From 3 To 4 Gear At 20 - 25 Mph
Mar 23, 2013
My car is 7k short of its drive train warranty expiring. I noticed a rumbling vibration when the transmission shifted between 3-4 gear at approximately 20-25 mph. Took it into the dealer, and their expert rode with me and verified that it indeed was vibrating, but that he had never seen this issue on the 2007 GS350 AWD. He said he would have to check around the country to see if others had this problem. Four days later, he advised me that he was told to flush the transmission 2-3 times and for me to drive it about 1k miles to see if that fixed it. Well, it doesn't do it anymore, but I'm not sure why, or that it won't do it again just after the warranty expires at 70k miles. I certainly don't want to look at a 4-6,000.00 transmission replacement after the warranty expires. The dealer obviously doesn't want to incur the expense either, under warranty. Even though the transmission does not rumble or vibrate anymore, should I ask for the replacement anyway?

I have a 2000 passat v6 with a automatic transmission, I was on the highway yesterday and 2x the car shifted down by itself from 5th to 4th gear. I noticed when I bought the car it had a slight tranny leak which I assumed was from the seal drying up because the previous owner let the car sit for a little bit. The first day I bought the car she hesitated going from 4th to 5th for like 3 seconds but every day after that it has been fine. I have been told by some people to flush it and get new fluid and a filter, and then other people telling me that the tranny fluid is lifetime and if you flush it your going to blow the tranny up.... What should I do, the day it acted up I got to where I was going then the car sat for about 2 hours and on the way home on the interstate it was fine like nothing ever happened. I drove it to work today there and back and again no problem.

Need to identify this noise? After starting the car after sitting overnight or anytime the engine is cold it makes this sound when shifted into gear. You can hear the sound dissipate and eventually go away but it has me worried.

First time Lexus and RX350 owner. Not familiar with the new type of shift gear. When I shifted the gear from Park to Reverse straight down instead of moving to the right first, the vehicle would jerk and make a thud sound. Not sure if this would have damaged anything. After I have get used to moving the gear to the right first before shifting down, I would still sometimes have this jerk/thud. But if I do the whole shift movement (shift the right first) real quick then the chance of getting the jerk/thud is much less. Is it a manufacture defect or just I am not doing it properly?

Not sure if this is normal. Only noticed it recently but my HI-LO gear lever vibrates. The faster I go the worse it gets. Why?
I spoke to a friend who's a mechanic. He reckons everything's fine. We just put some new grease into the transmission, etc.

Any way to adjust how much the outside mirrors tilt down when the car is shifted into reverse? I have looked in the Owners Manual and I can't find anything that addresses this. I feel like there must be some adjustment since sometimes the mirrors tilt a lot and sometimes they tilt just a little.
I have tried shifting the car into reverse and letting the mirrors tilt and then adjusting the mirrors with the adjustment controls to the preferred tilt angle, but they didn't retain the memory and went back to the previous tilt settings.

A month ago I had the Lexus dealer do a 50k mile service (although I have 68k). I work from home and rarely go anywhere. The miles are highway miles to North Carolina Mtns. I have a 2007 GX470 that I bought new. Tried going out last night to dinner and the car would not go into gear. The shifter would move freely but would not engage. When I tried putting it back into Park, there was a grinding noise, not bad but it was there. The car is UN-drivable. Before I have it towed to Lexus, is there anything simple I could check? The car drove perfectly the day before.

I have a 2004 RX 330 and the transmission kicked out of 3rd gear going around a turn. It felt like something gave way and broke. Now the transmission only works when the selector is in 1 or 2. It will not shift above 2nd gear reverse works fine. I have not experienced any transmission issues with this vehicle till now. The car has 215k miles so its higher mileage. The transmission doesn't make any strange noises while running in this limp mode. There was no check engine code flashed when the incident happened. I read a couple of message threads and saw some mention of limp home mode from the knock sensor. I think that this should have generated a dash code at least. I tried resetting the any codes that were generated with disconnecting the battery for 30 minutes. This made the problem worse and the car will barely idle now. The resetting of the codes did not fix the shift issue.

I just bought my 2007 GX470 last Friday. Last night I drove it home in the season's first snowstorm. I've got plenty of experience with winter driving and Toyotas, so I thought I knew what to expect.
I dropped down to 3rd gear for a long hill and the transmission or engine started surging. It would hold at 1100 rpm, then suddenly jump to 1400rpm when my foot was not even on the gas. Then it would drop back to 1100 again.
The car has 78000 miles on it.

I have 142k miles on my 2005 RX330 AWD. This week I can feel the transmission slip/shudder when shifting from 2nd to 3rd gear.
My local transmission guy is pretty reasonable but like most salesmen he's going to say rebuild it the entire transmission in lou of something less invasive.

Like the title says, I sometimes experience a long shift from 1st to 2nd. When the transmission is cold, it seems to shift fine from 1st to 2nd. It isn't until it is warmed up that I get a looong shift. It winds up,,,,, then it shifts. I have no problems in other gears.

I have a 98 GS4 and a 04 RX330 and one major issue I have with the RX, is the poor downshift response when slowing down, to say 5-10 mph and give it gas, the transmission takes FOREVER to realize I want first gear. If I am giving it 50% throttle at 5-10 mph after slowing and needing to get a move on, the throttle seems like it is there, but the transmission takes an eternity to realize "oh, you want first? hang on while I think about it", then it grabs first and LURCHES forward, giving everyone a very uncomfortable jerk.
My GS however, when down to those speeds is always spot on the right gear. Yeah, I know its comparing a GS to a RX, but wouldn't you think that Lexus would figure that one out?
Is the 04 worse than 05 or 06? Can I use an 05 or 06 trans controller and get some improved transmission response?
You can tell by the lurch, the throttle is responding to the driver's throttle pedal input, but the transmission isn't figuring it out till way too late. I don't get the lurch like at slower speeds and higher throttle input, but it sure makes for a poorly driving car.
I see the same problem when taking slower corners, get it down to 10-20 mph for a corner and the transmission won't downshift till AFTER the apex of the corner, despite what throttle pedal is pressed.

I have a 2000 Lexus RX300 with 210,000 miles on it. We recently started to have some transmission issues. It sporadically drops into 1st gear while driving. We had the transmission fluid changed, and it did work for a short time, but it has recently started again. Is my transmission going to completely fail or is this something that is serviceable? We are trying to decide whether it's worth it to keep the car and fix it and drive it for another 100,000 miles or sell it. It looks great and drives great, otherwise.

New to my 2008 GX470. 100k miles. Love it so far. However I think I am hearing a intermittent rumbling as I drive down the road. It is like the rumble from a radio base sound. It could be normal road noise but I bet it is not.
I have replaced the left front axle (grease boot broken), replaced the rotors and pads, replaced all differential and transfer case fluids (not transmission yet) and inspected all the suspension parts.

So recently I have been feeling this weird rumbling/vibration in my gas pedal when I really gun it. Whats weird is i feel it mostly in first and second. But i feel it only on full throttle and under boost. I am assuming it has something to do with suspension. But whats weird is it happened after i installed my dp. So would this just be a coincidence or something else? I do know for a fact that I need new strut mounts and bearings, but I've been reading up on them, and the symptoms aren't really similar.

The car idles pretty rough & loud but ive noticed its only when im in 'drive' with my foot on the brake, at stop signs/lights. Its also much worse when the engine is cold. It settles right down if I come to the stop and shift into 'park'. So as I roll to a stop and hold the car in place with the brake the engine starts vibrating.
I dont know much about these things but it almost feels like i'm restricting it by having my foot on the brake and the engine wants more gas or air or something (could be way off base, but thats how i perceive it)
The RPMs sit around 1,000 and as the engine idles/rumbles it gets up to maybe 1,200-1,400 RPMs which i didn't think was significant but im pretty new to this.
Forgot to mention the most important thing- there is a rumbling noise that goes along with the vibrating, again only while stopped, goes away immediately when i pull off the brake and hit the gas.

Recently purchased my first Toyota, a 2012 Corolla S with 76,000 miles on the ODO. I have a concern about a front end rumbling.
First, the problem...
This "rumble" (the best way I can describe it) starts becoming noticeable around 20-25 mph, depending on the condition of the road I'm on (it could be lower, but I'm in Michigan, all the roads are bad here). This rumble isn't a noise, but more of a low frequency sensation that can be felt in the car and through the steering wheel, and vibrates the rear view mirror. The rumble comes and goes, it isn't constant. Sort of like driving over a rumble strips put on roads before stop signs/intersections, it seems to have an oscillation to it. The rumble intensifies very little with speed. It doesn't seem to oscillate any faster or rumble much harder, it's just there.
Things I've ruled out...
Brakes. When I bought the car, the first thing I noticed was that the front brake rotors were slightly warped, so I installed new rotors and good pads. That didn't get rid of the problem, though I didn't really expect it to.
Tires. The previous owner had seriously over-inflated these tires. Once taken down to their proper pressure, they were noticeably cupped down the middle. These tires were also horribly noisy would not balance, so brand new tires went on (Michelins). The new tires greatly improved the ride, reduced noise, and got rid of a lot of other shakes and vibrations, but the "rumble" remains.
Wheel Bearings. I'm not 100% on this one, but as far as I can tell, it's not the wheel bearings. I've taken the car out on twisty roads and there is no change in the rumble through hard turns, nor any additional vibrations of any kind. Usually bad wheel bearings will exhibit some noise or vibration when being loaded in a turn, but not in this case, so I've ruled them out.
Things I'm not sure about...
CV Joints. I've never had a CV joint go bad or fail on me, so I am unfamiliar with the common signs and symptoms. I have inspected the boots, and they appear to be in good condition and crack free, though that doesn't mean a joint isn't failing. There's no clicking during slow sharp turns, but I think that would only present itself if an outer joint was failing. I'm going to get the car in the air this weekend to do a drain and fill on the tranny (the fluid is getting pretty dark, so I want to get some new in there).
I drove a Ford Focus for the past 10 years and a Ford Contour for 10 years before that, putting over 200,000 miles on both, and never experienced any sort of problem like this.

Tires just balanced and rotated yesterday (second time just in case done wrong before). New ball joints and bars installed about 50k ago. Left front shock may be bad, but only slightly.
The issue: At about 40-55 mph, there is a rumble in the cab, unknown origination. Everything vibrates, although it "seems" like the left mirror is shaking more. The seat, floor, steering wheel, everything vibrates.
When I let off the pedal, vibration and noise go away, even within the "vibe zone". It only vibes when any throttle is applied, even just a tickle. I brought the engine up to the vibe zone RPM (1500-1800'ish) while in park and neutral, all seems fine.
I checked the U-Joints, they seem tight. I don't have access to a scanner, unless I want to pay the dealer.
