Lexus GX 2004-09 :: Hard To Shift Into Next Gear When Merging Onto High Speed Roadway
Aug 12, 2013
2006 GX470 57000 miles loaded. I purchased this new and I was wondering if anyone on here can give me a bit of input on what you may think is going on.
My truck when merging onto a high speed roadway my truck doesn't seem to want to shift into the next gear. Almost like if it was a manual I would have to shift it. It really whines out before it shifts.
Also My husband is hearing a humming/vibration from the rear when we are doing about 65 steady I've already had my tires removed and checked to see if I may have thrown a weight or a broken belt but everything is good. I have Michelins on the truck and they are about 2 yrs old. No damage on the tires I have them rotated every 5000 miles.
I had the truck in for service and told them about this. The Lexus service rep told me his mechanic told him he found nothing. I asked them to check again and he said the mechanic would take it home to drive it at a speed that was needed. Again I was told nothing was found. Got the truck back from the seat repair don't even think the truck was taken home.

I had the cam gears on my 2009 RX350 replaced and after the replacement I noticed that the engine noise is louder. It's louder after a cold start and idle. And it's louder when driving. Even the transmission sounds like it's struggling - it's taking much longer to shift into higher gear and occasionally it makes a whining sound when it shifts. Also, I'm hearing whining sounds when I steer the wheel (which was diagnosed as potentially caused by a faulty power steering pump, which by the way did not cause any noise prior to the work done). The replacement was done by a reputable Lexus dealer.
The Lexus dealership claims that the engine noise level is within acceptable limits even though it is much louder than before the cam gears were replaced. They deny that the replacement cam gears could be defective or that the replacement itself could have gone wrong. They have acknowledged the noise coming from the transmission and have offered to replace it (still under warranty so no cost to me). Now what is strange to me about all this is that prior to having the cam gears replaced, the engine noise was very quiet. The only occasional noise came from the cam gears on cold starts but lasted a second or two.
Now I don't know for sure that replacing the transmission will fix the noise issue. And it is so strange that the transmission seemed fine prior to the work done. What's happening here given the facts? Could replacing the cam gears somehow damage the transmission? Is there any interaction between cam gears and transmission. Aside from the transmission, what could explain the much higher engine noise (when not shifting so transmission not a factor) after the cam gears were replaced?

,My wife drives a 96 Civic DX Hatchback, 5 Speed. It has about 160,000 miles on it, and she only drives it to work and back (a 15 minute drive via the interstate).
Just yesterday, she told me that the clutch feels 'looser' than normal, for lack of a better term. When it's first started, it's hard for her to get it into first and/or reverse, but once driving, she says the shifting is fine. When she's driving at highway speeds in 5th for a while, then has to get off at her exit, she said it's hard for her to get it back into 1st gear. She says she feels like she has to push the clutch harder than normal to get it back into 1st gear.
I don't know much about manual transmissions, and am hoping for some insight into what the problem(s) may be?

My 2008 seems to be having some intermittent trouble shifting into the proper gear at a couple of speed ranges.
Occasionally I'll start it up and pull out of a parking space (or leave a stoplight) and it feels like it's stuck in 1st well after it should have switched to a higher gear (I sometimes feel the upshift at about 10* mph). If I continue accelerating and hit about 40-50 mph, once again it appears to stay in the current gear instead of shifting.
When this issue is happening, the car feels even more underpowered than usual and takes way more throttle than it should to accelerate. This results in a cruising RPM of 3.3-3.5k at 60 mph. At that speed the engine would normally be doing about 2.2k RPM. Similar power and RPM conditions exist in the lower-speed range, too.
This whole thing is usually preceded by a rough shift into gear (D or R) when I first start the car. It's always had a slight lurch in the appropriate direction as I take it out of park, but this is really noticeable.
If I stop the car and come back in an hour, it (usually) appears to have reset itself. I can drive around and the transmission control is as good as always.
This has been going on for about a month, with an episode maybe every week or two. I took it to a shop and they didn't find any problems (I told them about the weird shifting and lack of power).
Does it sound like this is what's happening (it's not getting into the right gear)? Thoughts on what I should do? I can't really remember the speeds.

Last week I was on a dive trip and my RX remained parked outside for a week. As I was returning home and I was merging on the highway my CEL appeared; I used my scanner and the code was p2195, which I cleared. My RX was driven for about 5 minutes before merging onto the highway.
On my way home I needed to stop for gas, I filled up and them merged onto the highway and the CEL came on again. I used the scanner and the same code p2195- which I cleared.
I completed my drive home, and have only been doing short city driving since then an no CEL's.

I own an automatic transmission 2004 Hyundai Accent with about 180,000 miles. I bought it brand new, but it seems to be having trouble shifting into the right gear. Many transmission "specialists" keep telling me they can't figure out what is wrong, aside from offering to completely rebuild my transmission. The car has the following symptoms:
1. At a stop sign or red light, my car doesn't always begin idling properly. Sometimes it just won't go anywhere at all, even with the motor running.
2. As I drive down the highway, it acts like it jumps into a higher gear for no reason. It sometimes resets itself with no action on my part.
3. The car jerks back and forth, not seemingly due to shifting into gear, but randomly.
4. The check engine light does not come on often, but by the time I can use a DTC reader, the light goes off.
Everything seems to be intermittent, so I can't replicate the problem on-demand for anyone who wants to inspect the problems. Is there anything I can do? Is there an easy way to figure out what's really going on? I'm assuming this is transmission-related...

GS350 ... The behavior is such that under hard braking, the transmission struggles to get into 1st gear from any speed to 0 MPH. Only happens under hard braking. Basically it feels like the tranny is slow in getting back to first. If im driving at 40 and brake hard to 0, once i stop, the tranny feels like its still getting into 1st for the next 2 seconds and then it hurches confirming it has reached 1st gear.
The second behavior is that when I am driving at 70 MPH or any speed, and i brake hard to reduce speed 10-15 mph, the rpms will go from its normal 70MPH Rpm ~2000 RPM and drop to idle speed around 500RPM while the car is still at 60 mph.

It's a 4 cylinder 5 speed, and once or twice a day when the light turns green and I go to put it in low gear, it just doesn't want to go into gear easy. It's like the syncro isn't happy or something. The clutch is depressed all the way and not dragging.

For the past 3 months, upon shifting from 2nd to 3rd gear, the car lurches forward in a hard shift. Sometimes, it is nothing more than a benign "clunk", and other times it is violent, as if hitting a wall. This does not happen every time it shifts and even under identical acceleration, the results vary from none to violent. The number of violent shifts vs. small jolts has increased over time, and all other transmission functions and shifts are fine/normal. After much time researching the inter-blogs, I have come to no consensus on what is causing this or how to fix it.
Some say it is the adaptive shifting program and it just needs updating and others say it's the tranny and a rebuilt tranny replacement is the only thing that eventually fixed this problem (though one posting on the Hyundai forum is of the same exact problem, but the solution is worrisome -- contact negative battery terminal to positive, let sit for 10 min, reconnect, then drive at 1/3 throttle, shifting through all gears a dozen times. Poster says this resets adaptive shifting program and worked for him).
Finally, today, I took it in for a diagnostic with a local transmission specialist, and they could only replicate the hard shift once, but when that happened, he said the car went into limp mode and read two codes: P1193 and P2127. The car has never gone into limp mode (P1193) nor shown an signs of suppressed RPMs associated with this mode. Also, he seemed to focus his attention on the low voltage to the pedal position sensor (P2127) as being the major issue that is causing the hard shift. I also called a past dealer that worked on a similar issue with the car when I bought it used 4 years ago and they recommended updating the adaptive shifting program as they did last time; though I don't recall if the shifting issue was the exact same problem I am having now. So, a few things:
Does this sound like a computer issue or a tranny issue? Could the pedal position sensor having low voltage cause a shifting problem like this? Any merit to the connecting the battery terminals idea? Should I be wary of the mechanic that did the diagnostic today?

As we know, flashing dash lights are a part of owning a Volkswagen. Even moreso a modded Volkswagen. Last night I was treated to my first CEL during 3rd gear pull merging onto the highway. At 4200 RPM, the car cut timing and throttle ferociously and the CEL came on and flashed for about 10 seconds. The road was rough so I anticipated that it was the car registering a knock and Bronson said it could've been that. I pulled over, checked everything I could visually at 1:00 AM and it all seemed fine. Car accelerated and boosted well from then on, on the way home.
This morning I got in for the drive to work and noticed within 2-3 miles that the car was idling strangely. Not long after, the CEL came on. It would surge from 1,000 to 1,300 RPM randomly. I took it back home to pick up my VCDS and my laptop and scanned the following codes:
Code:
000768 - Random/Multiple Cylinder Misfire Detected
P0300 - 001 - - Intermittent
Freeze Frame:
Fault Status: 00100001
Fault Priority: 2
Fault Frequency: 1
[Code] ....
Since then I have checked:
- Intake hoses/clamps
- Intercooler hoses/clamps
- Diverter valve hoses/clamps
- Throttle body pipe/clamps
- PCV hoses (The PCV on the valve cover was replaced by the BFI catch can. It has been on the car for over 6,000 miles with no issues, and all of the fittings are tight.)
- Boost tap hoses/clamps
I reset the codes and drove it to work and all was well, but I'm staying out of boost until I find out what the problem is. The car has stock plugs, stock coils and stock DV and only 7,800 miles.

I have been having an issue with my 4-5 gear shift under hard acceleration and know that a rebuild is due soon but I was wondering if any high performance kit available with all the clutches and friction discs needed to rebuild.

Could my brake issue be related to my transmission problem? Neither are constant. Brake problem= sometimes the brake pedal feels hard, like there's no power brakes (I drove a car once. ..looong time ago. .. that had no power brakes or steering) but it will kick in after a short distance. Transmission prob= seemingly unrelated, is a problem shifting from 1st to 2nd gear. This has happened maybe a 1/2 dozen times, the first time and mostly when in heavy commute traffic and when going between 1st and 2nd gear because of the slow commute speed, but also at other times when not in lengthy slow commutes. When it doesn't shift, the odometer doesn't work (shows only dashes) and an engine light comes on (the sprocket/gear looking one). Usually the transmission will eventually shift and the light goes off.
I read that the brake problem might be a vacuum hose problem? Something about a booster? Is this dangerous? or is it like having a car w/ no power brakes? Going to have my transmission looked at this week. Read on another site about dropping valve seats on this year car. If there's a major transmission problem, I'm wondering if it's worth fixing? I changed, timing belt, water pump, front and rears brakes, tires. 143,000 miles.

Background facts:
Tranny swapped from my 4 speed auto to a 1.8t o2j 5spd
13lb. Light flywheel
Powerflex dogbone mounts
Peloquin LSD
The problem: Very hard to get a smooth shift from gear to gear. Trust me, I know how to drive, but I can always feel the car shifting into a different gear if you know what I'm saying. On my friend's bone stock Jetta, I just let the clutch out without gas in between shifts and you don't feel a thing.
On my car, you feel EVERYTHING. People have told me the light flywheel will make the ride more uncomfortable in many ways, especially since the RPMs drop much quicker in between shifts than stock.

Taking my car to get the brakes serviced this week. Every time I brake at a high speed the car shakes. I am guessing best case scenario I get the rotors resurfaced and worse case new rotors.

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 2004 RX with 82,000 miles, well maintained. Lately the engine will start but the warning lights won't go off and the gear shift won't move out of park. I have to keep turning the vehicle on and off until the gear shift will go in reverse.
It doesn't happen every day but off and on over the past month.I've had numerous brake light switches replaced which could maybe be the lights, would that affect the transmission too?

Lately my 2007 GX470's steering wheel has a shaking/vibrating problem whenever I apply the brake at speed above 50 mph or so. Without braking or with braking at slower speed, there is no problem at all -- everything is glass smooth.
1. I assume the front brake rotor is warped?
2. Will I need to change the rotor or is there a way to fix the warp (it that's the problem) without changing the rotor?
3. Approximate part & labor cost?
I plan to bring to dealer for a check up but would like to know ahead of time what to expect.

I own an 08 Rx350 at 70k miles now. This is my first car ever; my parents bought it brand new and gave to me as gift after I graduated from college. I try to take good care of it; whatever the dealership tells me to replace, I replace it. I follow the maintenance schedule and owners guide to a T. I never really paid attention when my parents drove this car...but I don't know why my car vibrates when I get maybe above 60 mph and try to apply the brake. I do not brake hard and now I pretty much avoid applying brake and just let it glide. Is this normal? Whenever I visit the dealership they do a complete check up. All the check up results are normal;nothing wrong with tire trims, brake pads, suspension etc.

I have an 04' R32 with about 56k on it. Here's the problem; when I drive it hard and speed shift from 2nd to 3rd it grinds just a little. It doesn't do it when I'm just cruisen grany shifting. For awhile now I've been thinking that the synchronous from 2nd to 3rd gear was going bad, till I talked to a friend with a 20th GTI who said that the 6 speed trannies will start to do that, and there's really nothing you can do about it. Is this true that I just have to deal with it or can it be fixed?

So my MK7 GTI is my first manual car...And I am having trouble doing slow speed maneuver most of the time...
I often found myself in a situation where the speed and the rpm of the car is too low for 2nd gear, and when I try to shift to first, it would't let me, unless I almost come to a complete stop....
I tried to press the clutch all the way in, then rev up the rpm, then release the clutch, but it doesn't work much, the car still jerks...
