Lexus GS 2006-11 :: GS300 Rough And Jumpy Transmission When Slowing To A Stop?
May 31, 2005
Notice roughness/jumpiness in the transmission when slowing to a stop, or crawling along (like in a shopping center)? it's quite evident on my car, and perhaps i just have a problem that nobody else feels.
It's as if the tranny is downshifting when slowing to a stop, and I can really feel it...makes it difficult to come to a smooth stop. and then if I'm moving very very slowly in heavy traffic, it seems to be "wandering" between 1st & 2nd...something like that...and it's very jumpy. Not smooth at all.
I realize that Lexus may come up with some reprogramming for trannies (that happened on my '01 GS, and it made a big difference).

I bought a 2005 3rd gen about 8 weeks ago and I love it except for one problem, a really bad idle/vibration through the cabin when cold starting, it improves when the engine is warm but is still noticeable.
It went back to the dealer where I got it and they gave it a full service, new plugs, oils and filters and replaced the transmission oil too after the check vsc and engine management lights came on.
The codes pulled showed a misfire on cylinder 2, the dealer said the service would cure all and sure enough no more vsc lights but the rough idle and vibration are persistent.
The car has only 78000 miles and I'm pretty certain a Lexus isn't supposed to behave like this.

I bought my 06 GS300 AWD with 104k a year and half ago and have noticed the transmission sticks while shifting. This is prevalent during winter or cold driving.
These are the cold symptoms w/o Snow Mode active:
-sticking between shifts (gears 2-4).
-on highway coasting speeds, take your foot of the accelerator and the Tac. needle bounces.
-downshifting to lower gears the car pushes forward further than expected.
-coming down a decline with your foot on Brake, the gear upshifts instead of downshifts (has happened after driving for more than 20 minutes).
- high Tac. reading during warm-up drive, have to depress brake pedal further, to prevent collision.(this one I expected since all Toyota vehicles that I've owned has done this).
I have talk to my local Lexus dealer and a tech mentioned this transmission has been known to do this while it's cold.
So, my question is, should I consider changing the trans. fluid to see if the problem goes away?

My 2006 lexus gs 300 has this annoying issue where if i would accelerate with light throttle from a complete stop, the car would kick and sort of shake.. This happens the most and basically every time when i would slow down at a stop sign with using the brakes, then let go of the brakes and accelerate again, the car would feel like it has some sort of throttle delay and then you feel a heavy push/kick like the wheels are confused..

During low rpm cruise and light throttle acceleration below 2000rpm the transmission feels like its lagging or doesn't engage until after like a second or two after you press the gas pedal down. Been happening the past couple months and I would like to find a fix for it instead of buying a used trans or new trans.
Just picked up this code the other day as well.
P2757: Torque Converter Clutch Pressure Control Solenoid Control Circuit Performance or Stuck Off
Recently changed the fluid over a year ago with Toyota ATF @ Longo Lexus. Car has 140k+ miles on it.

When I accelerate from a stop, the car jumps, slows down, jumps again, etc... I do hear a noise when I accelerate rapidly on the highway, almost like a leak somewhere, but I'm not really sure.

I bought my 2006 Prius used and I had just put it over 100,000 miles. The dearlership has replaced the HV battery under warranty and suggest that I replace a slightly leaking waterpump and cracked belt, said nothing about the transmission.
My concern is, my transmission. When the car switches from electric to the gas engine, the car jumps a little bit, and it's an obvious and not smooth shift. And when I put it in Park, the vehicle rocks back and forth a bit, shifting a few inches before coming to a still position. Is this standard with other 2006 Prius? I drove my friends 2007 Prius and the shift seems smooth and it doesnt rock when you put it in park. Should I be concerned and if so what should I do?

More lately I've been noticing that when moving slowly, if going over a bump in the road of any sort, the steering wheel seems loose and the car wants to jump to one side or another slightly.
Picture moving straight ahead, and hit a rough section of or a small pot hole, and the steering wheel will move by itself to the left or the right quite a bit. I haven't noticed anything on the highway.
What can cause that? How should I go about describing to the service advisor so that it doesn't seem trivial? Last thing I want is a steering rack or major front suspension component slowly dying right after my warranty runs out. All I know is that it has struck me as "hey this doesn't feel normal".
Am I just being overly sensitive now that my powertrain warranty has months left on the clock, or does this sound like a legitimate concern? The last few things I've had them look into at the dealership during other service visits have been returned to me as "no problem founds" and I'm starting to feel like I'm just going crazy.
After some additional googling, it seems like I'm describing something commonly called "bump steer"... how much bump steer is normal for this car with stock suspension, I don't know... all I know is that I seem to have become acutely attuned to it whereas I never noticed it before. Hopefully I don't get the "we didn't notice anything wrong" again if I mention it, and whatever it is, is covered.

I'm a long time Lexus owner but new to 3GS, I've searched around but couldn't find an answer. Is it possible to sync my phone book to the car?

I have a 2006 LEXUS GS300 AWD. I loved how it looked stock but I wanted more. I replaced the stock shocks with Brian Crowler coilovers and got some 20" Niche Verona staggered wheels. I dropped it about 2 inches. The problem is that when I take off I have a vibration that comes from the car up until i reach about 20 miles per hour. However, when I put on the stock wheels there is no vibration. I got it put on the rack and all the arms are fine. I even checked the tires and the rims for any problems and they are fine.

I bought in my 2006 GS300 to Lexus dealer 2 weeks ago for the engine misfire issue and were told to call corporate 'cuz it's over the 9 yr period for 1 month. Called and told me to bring it back for inspection on the issue. Dealer performed the test and found the misfire, but got a call from dealer that they won't cover it because I missed it by 1 month. I had explained to the rep that we moved around quite a bit and found out about this not too long ago.

My '06 GS300 has a bulb in the driving lights (inner set, closest to the grill) that is out. It is the small light that turns-on when you turn the proper night-time lights on. SO, my driving lights operate normally, but when I switch the lights on, and the smaller bulbs turn on, one is out.
I was able to locate a post that suggested a 194/t10 LED light for replacement. How to confirm this is the proper bulb for the job? Also see these listed as #2825 in halogen.

Owning a Lexus . I recently bought an '06 model GS300 and have just had an issue appear with it.
Issue is that, whether in drive or reverse, the car accelerates on its own - not very quickly, but quickly enough that it'll crash me into my garage door if I'm not careful.
What this could be? Variously, I've read that it could be a Throttle Positioning Sensor, or Idle Air Control valve. Some things I've read suggest it could be air conditioning related (though I don't understand that one...).

I have a completely stock 06 GS 300 AWD. Just noticed this morning in traffic that my lights keep wondering up/down while I'm stopped ?? Arrived at work and watched the lights shinning against the office wall, still going up/down... I'm assuming hunting for level ?
Not sure if this is happening while driving.. needs to be a fair dark night & smooth road to see if it is doing this. Because both lights are doing this simultaneously I'm thinking its the control module ?

I have tried resetting the ECU via fuse pull. I have confirmed brake lights work (as do all of the lights). Car has just 66K and simply will not start at all. Battery terminals clean and connected.
ECU?
ECU Capcitor leakage?
This thing is a blast to drive, but has so many issues and is not stuck in my garage!

I was trying to find a guide on how to change out my reverse lights to LED, I'm having problems removing the panel. The guide i found on here had all the pictures removed. I'm also trying to change the lights for the make up mirror.

I have a problem with the rear right door on my 2006 GS300. It wont unlock no matter what I do. When I try with the key it just makes a funny whirring sound, and the inside lock switch does nothing at all. I need to take a look at the door but obviously I cannot get it open to do so.

I have a '06 Mercury Mountaineer, right over 100,000 miles. For the past few months the car has started to make a sound and even produce an "clunk" that I can feel when I am slowing down to come to a stop. It only happens when I slow down to around 3-4mph or slower. The transmission has only around 10,000 miles on it. What could be causing this?
