Lexus GX 2004-09 :: Transmission - When Starting From A Stop Car Will Not Accelerate Normally
Nov 11, 2011
From time to time, and always unpredictably, the transmission acts up. When starting from a stop the car will not accelerate normally, putting me in jeopardy. Also, shifting automatically is a problem.
I tried shifting through the gears and got mixed and unacceptable shifting. Depressing the accelerator only increases the RPM, the speed hardly at all.
Is this a problem in the transmission or in some electrical control of the transmission?

So, my wife tells me that the interior lights have been flashing on. When she accelerates from a stop that blink on for a second. I figure she has not shut a door well but it appears that she has. I have not had a chance to check the doors.

I have hesitation as I accelerate especially starting from a stop. It will continue until cruising speed. Funny thing is when I put the cruse control on the hesitation stops and it runs fine. If I want to accelerate while on cruse the hesitation starts again until I let off the accelerator. Is it the TPS ? I changed it two months ago.

I have a 4 cylinder 2009 Sonata with an automatic transmission and it does not accelerate smoothly when starting out from idle. A slight touch on the accelerator pedal causes the motor to accelerate hard as though the pedal was pushed down a lot further than "a slight touch". Is this normal or should this car accelerate smoothly? I am wondering if there is a common problem with either the accelerator pedal sensor or maybe with the throttle servo.

I am not the original owner of this 1990 E250 cargo van with a 302 in it. I am trying to troubleshoot this shudder I am having. It only happens when I am just starting off from a stop. Every other place the tranny runs and shifts great. I trying to find a starting point and after reading a bunch in a bunch of different places, I am confused as to the tranny I have or even had.
It has in big bold letters METRIC on the bottom of the pan. It also has Automatic Overdrive and Ford on the bottom of the pan also. It is a 14 bolt pan with the two rear corners of the pan chamfered off. I see now it is DEFINITELY the AOD installed and NOT the AODE. The thing is my steering column is labeled 1 D and OD. That is a 3 spd overdrive to me. What the heck is going on? How can I tell what the tranny was that came out of the van?
When I look under the van at the shift linkage, you can definitely tell the linkage is colored red which to me looks like somebody has been down there playing around. Is it possible to put a AOD into this van with the steering column the way it is? Could this be a reason for my early shudder at starting off from a stop? Once I put my foot in it or get moving at a quicker pace, the shudder goes away. Something is not right with the way this tranny is set up. I am not even sure where to start.

So a couple months ago I had a transmission problem. It shifts high and hard all times and after the "od" light gets going (after it gets warm), the transmission slips (like riding clutch) when starting from a stop. If I went from drive to 1st gear with the selector and back, it cleared the slipping problem for a bit. I did an oil/filter change and about 50 miles later the truck is running fine, no issues. One day I hopped in it to go to work and it was like nothing ever happened. Fast forward 1,500 miles later. I start to notice the transmission is subtly shifting weird, like a small jerk when shifting. It gets worse over 50 miles and now I am back to the above problem. Is there a way this could be a sensor or solenoid problem? I never heard of a transmission correcting an issue then starting at it again so much later.
I don't like fixing or working on an issue unless I am at least 95% sure what the problem is. I also don't have $2k to plop down on a repair at the moment. Would it be worth it to take this to a dealership and see what trouble codes I am getting? I would try a transmission shop but it's not guaranteed they will have the test equipment to check a ford transmission. Also a friend said that AutoZone and other stores can't check transmission codes. So what's the best option here?

This morning as I was driving to work, my truck hesitated as I tried to accelerate from a stop sign. I pressed the pedal and nothing, almost felt like it was going to stall. After about 3 seconds it started driving again and I had no further issues. It seems to only do this in the morning when it is cold. It has done this a couple of times before, but usually it recovers almost immediately. I had no CEL come on. 2007 F150.....

So of course the dealership isn't going to diagnose this since "the car's not supposed to be driven that way" - but I get a nasty rumbling noise when I accelerate from a dead stop with wide open throttle. It only lasts for the first few thousand RPMs in first gear, and after that it is gone.
I was guessing that it might be the transfer case or something like that, but it's really hard to tell. I do have AWD. I did not have any such problem in my previous GS, which was a 2007 (current is a 2010). It's worse when I accelerate around a corner, and it also makes a small noise when I'm going above 80ish mph, which of course the dealership isn't going to diagnose either.

I have a 2004; 4cyl Sonata, that jerks when I accelerate from a stop light or when I step on the gas, it jerks and sputters while passing another vehicle, then it gains speed?

When I accelerate from a dead stop I have this squeaking that comes from the back of the truck that goes away after a few seconds. Then when I get up to about 50mph I have this really annoying vibration. Its not a real heavy vibration but it is there. I am thinking it could be the universal joints, am I way off here or what?

I have a 2008 ford f150 4.7 liter 4x2 & the problem I am having is when coming to a stop when I accelerate there is a slight shimmy in back end or could be described as a vibration for just a few seconds and then you don't feel it anymore until you come to a stop & restart. Once you have pulled off it will not do it anymore out on road. I checked fluid & it is not low in back end. Transmission shifts good so what could cause this.

I am trying to find out why my F150 Supercrew with a 5.4 and is 4x4 as I start from a stop and I give it gas it shifts from 1st it shifts fine. but when it goes into 2nd gear it starts laboring really bad as if it has no power. If you give it little gas it seems like it has no power. So I decided to push the overdrive button off and it still does the same thing. I have never pulled a trailer in overdrive and it decides to shift automatically into overdrive when I am driving below 45 mph.

I got a problem this morning my car was juddering when I tried to accelerate my Toyota Prius 2004. When it's over 40MPH the car runs smoothly. After few hours it increased and now its jerking and juddering big time. Also when my car is moving the "Traction Control light" flashed even on dry tar roads. When I try to run from the battery the car runs smoothly at any speed. Also on neutral, the car idles fine and no juddering. Since few months I felt like the clutch plates are slipping and engine revs high than normal only when it's running on gas. Seems to be okay on battery.

i have a 04 f150 2WD I've been noticing a slight vibration on initial takeoff, it only lasts for a couple of seconds then it goes away. I have the "non serviceable drive shaft" the u joints are staked into the yoke. there is some up and down play where the drive shaft goes into the transmission extension housing. Does that play is normal or what may be causing the vibration?

2006 F150 FX4 5.4L, 118k miles... At highway speeds (45-50) and (55-60) as I am slightly accelerating it feels like the transmission or maybe ignition system is skipping a beat. Kind of feels like a small bump. I replaced spark plugs with motocraft about 35K miles ago and recently all transmission fluid via cooler line. Had some concerns about system flush so I just drained and refilled entire system via cooler lines. I have read that it could be my COP's ...

Have a 2004 GMC 4x4 extended cab light-duty Sierra 2500 with about 40 K miles. When attempting to start and drive the pick-up after the pick-up has been parked for a few weeks, the vehicle has to idle for perhaps 1 minute before the automatic transmission will start the move the vehicle. Also have similar 1991 GMC pick-up that will engage almost immediately after starting the vehicle, despite having been parked for a similar length of time. Did not seem to notice on 2004 when the vehicle was new, but, has become more apparent during the last year. GMC maintenance and repair have no explanation. Once the 2004 is warmed-up and driven, no problem - the transmission kicks-in immediately; but, not after being parked for any extended length of time. So what gives here?

I recently bought a 06 GX470 w/ 70k miles and noticed vibrations/sputtering when i accelerate during a turn. For example when you back out of a parking space, turn your wheels all the way and go. It happens when i turn right and left.

I have GX470 2009, now a little over 80000mileage. The car has been serviced by Dealer all the time. Recently, it has been served brakes, rotors, and new tires, cost a lot of money because no warranty. After the last service, I feel car has vibration around 30mph, not steering, no noise, it is gone when I release gas or just simply accelerate. It is very smooth and steadily at the high speed. I called the dealer and was told there might be driveshaft problem. I did find one side rube boot has a little very dark grease leaking (actually not leaking). Just use my finger to remove a little around the end of boot.

Dropped my car off at the shop due to the transmission lag from stop to slow speeds. Sometimes it feels like I was dragging sandbags. Then all of a sudden the car wakes up and goes.
The shop said the fluid "looks" fine but seems to think there might be too much fluid in it. So here we go with a transmission service. I hope this fixes it.

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).
