Lexus GS 2006-11 :: Tranny Struggles To Get Into 1st Gear From Any Speed To 0 MPH During Hard Braking
Jan 21, 2016
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.

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.

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 recently bought a 2002 Accent with the 1.6 auto 133000 miles. I have been reading the postS around here about the crappy transmission. My car seems to have some life in the tranny still but it has slipped from 3rd to 4th gear around 45 mph when i get on the gas too hard. Its also a little sluggish to start off. My question is should i change the fluid out knowing i have a slipping issue? The reason i ask is that last time i changed the fluid and filter on a Jeep that was slipping i ended up having to rebuid it. Is that a real possibility if i change the fluid in this Hyundai?

I have a 90 Cutlass Cruiser SL and it is shifting real hard going down to first. Other gears are fine. Checked motor mounts, ok. Also stutters at higher speeds in OD but when I kick it down to drive it quits. She has a lot of miles but I can't afford a new car.

I have a 2006 GS RWD the transmission started acting weird 4 month ago went to many workshops and no codes were found in the computer and my problem is that when i am moving in the car for more than half an hour and stop the car seems hard and jerking while shifting to 2nd gear and if i put it in tiptronic it go to 5th gear immediately it seems ok when the transmission is cold so what do you think it has got 125000 miles on it and what is the normal temperature for the transmission so i can test it with mini vci...

My 2007 Prius brakes extremely hard at low speed (while I am applying the same amount of pressure). While decelerating, I let the regen braking do most of the work until I get to about 10mph, then I press the brake so I will have equal pressure until I stop. When I get to about 5mph I feel almost a lunge where the brakes aren't working as hard and then the brakes take hold extremely hard. My prius has been doing this for awhile not depending on the weather, but I finally noticed it worse than normal yesterday when it was raining and my car braked hard and actually skid and the traction control light came on.

If the front rotors are warped would I not feel it when braking anytime and not just braking hard at high speed?

Sons saturn will not go into gear after a hard braking action. The shifter will move, the car just acts like it is in nuetral, engine revs with gas, no movement in any gear or reverse. After waiting for a few minutes he can put it in gear and go as if nothing happened. I have checked the fluid, its nice pink and clear and full. He says it has happened 3 times in the past week, has driven it for over a year with no major problems. He is 17, but seems decent with a manual.
I have tried to replicate but can not the car drive good, no shifting problems on normal driving and no check engine lights.

With 8 speed tranny has the clanking/clunking noise when shifting to P? When I park my car and shift from R to P there is a clanking/clunking noise and I feel small vibration on shifter itself when the noise occurs. It happens all the time and the noise loud enough. Is that normal? Up to this moment I thought it is normal (it still very well maybe) until I drove my friends Audi that does not have any noises when playing with the shifter. My Audi did not have that either.

I have a 2006 Nissan Sentra with about 58k miles on it. When it shifts into gear I hear a slight squeak, almost like a bushing or something like that. It does not sound mechanically related. More of something squeaking or loose etc.

I have an 03 F350 4x4 dually. Was pulling hard left at low speed when braking (front). Replaced pads, calipers, rotors, hoses and tires. Still the same problem. You can feel the abs activate right before it almost locks up the left front brake (basically will pull the steering wheel out of my hand). BTW the abs light does not come on.

2010 RX 350 NAP ... Brand New and OEM where it would apply : Tires (Conti's LX20s)
Brakes / Rotors (had same shake before replacing and did not improve after replacement but maybe I am dealing with a bad caliper here)
Tie Rod Ends
Stab Links
Lower Control Arm Ball Joint
None of which have solved a vibration issue thus far. Strut feels solid and the corner push test had the car settle out in less than 2 bounces.
If car has sat a while the driver front (where the issue lies) feels like a imbalanced tire/bent rim (rotated the wheels just to be sure it didn't follow the wheel/tire) or like a broken belt. The tires are almost brand new and only put them on because I was trying to eliminate the point of issue.
When braking, a light touch to the brake pedal makes a almost light clank sound (like weight shift is causing the clank or perhaps a sign of a bad caliper (although pad wear looks even but didn't have rotors rechecked but even with brand new rotors it was there so I don't feel it's a warped rotor plus the vibration is there even when not applying the brakes.
There is only one control arm and the bushing didn't look cracked beyond the normal surface cracking I have seen on most rubber bushing. The upper support is from the strut so perhaps a bad strut or maybe strut support/cap/bearing?
At a total loss as the local garages cannot find anything wrong. My thought was a bad wheel bearing, although there is not any grinding sound that you typically hear when a hub is going bad.
Could also be the CV Joint but not sure how to tell if that really issue the issue unless I replace all the other parts first (hub, caliper, strut/support/bearing).

When I brake very hard my right front wheel will skid, it releases quickly if I modulate the brakes. I removed the calipers to check for any frozen pistons. They are free. Pads are even and the rotors are good. I did bleed the system and no difference. what would cause this? Since I have looked at the mechanical aspect I wonder if there is sensor issue, is that a potential? I am not even sure if there is a sensor.

When I brake hard. My truck wants to veer right. It drives straight otherwise.
I recently had my front shock replaced and prior tp that my truck did the same thing, although it was much worse since my left front shock was leaking. Originally I thought it was pulling because of the bad shock but now that thet've been replaced I am not to sure.
Alignment issue or something else entirely? Coud bad rear shocks cause the issue?

I have a weird problem with my 2008 Elantra GLS 86K Miles on it. I did a couple of searches on this problem but didn't find any threads. About a month ago I noticed that when I braked hard at highway speeds 65 to 70 Mph I would get a noise that sounded like I was driving over the rumble strips on the side of the road. The rumble was the same frequency no matter what speed you are going, it doesn't get faster or slower. The problem slowly got worse to the point that it would happen at 25 to 30 Mph. The noise sounds like it is coming from the front but I can't tell which side. I figured that it was probably rotors and time for a brake overhaul so I replaced the rotors, pads and hardware on the front and the back. I used synthetic brake grease on the slides and guides. I also replaced the brake fluid with synthetic DOT 3.
When I did the back brakes I found that the wheel bearing on the passenger side was leaking lots of grease so I replaced it with a Timken bearing. (I live over an hour away from the nearest dealer so I did the repairs myself.) While I was working on the bearing I pushed the rear shock up and out of the way and it stayed in the up position for quite a while, aren't the shocks under pressure and usually push right back down? (Just an off subject thought) Well after replacing the bearing the rumble strip noise went back to just happening at speeds from 45 Mph and up. I was also thinking of pulling the fuse on the ABS and seeing if the problem goes away but will pulling the fuse hurt the car in any way or trip a code? I know what the ABS sounds like and this is not the same noise you get when sliding on ice.

Ever since I start driving the car I always noticed at like around 5mph no matter how light you touch the pedal from rolling its a bit jumpy. Not sure if its a major problem or not... also the tranny is starting to feel a bit not smooth btw almost at 80k miles 07 GS350.

On my 2006 Camry, my ABS comes on intermittently when braking (~5% of the time) and the speed is very slow (5 mph or less). Exact speed is hard to say. I think one of the ABS sensors is misreading. No ABS fault light on dash.I have an explanation of how to check the sensors for AC voltage when spinning the wheel using a DVM.
1. Without a lift can I check this under the hood instead of at the wheel? Possibly at the plug into the ABS module.
2. Someone else on another thread mentioned that their dealership hooked in a monitor and drove around.
When I asked my dealership how they would diagnose this, they said they would do the same check as I mentioned above (#1). This would be expensive and since it is intermittent, they might not see anything. Do this monitor exists and what it is called?

Have noticed a thumping noise when braking at a Low speed on my 2013 RX 350. Brought it to the attention of my Lexus service mgr at the 5000 mile service. He did a test ride and heard the same thumping sound. He then test drove another 2013 RX at the dealership which made the same noise.

I own a manual accent from the 2000 that I have since last December. Fuel pump and battery are new, I changed them after getting the car.
The issues I have and I think they are due to the same reason, are the following.
1. Sometimes, when I turn the key to on position and before cranking, the engine light blinks and the car wouldn't start. Then I remove the key and try again until the light doesn't blink and then the car would start. This could be the second time, the third time or after several times. When the light blinks and I try to start the car, I can hear the fuel pump and the battery working, so the problem must be somewhere else. Also, this issue happens very randomly, it may doesn't happen during two weeks and then it happens one day and next day is OK again.
2. Few times it happened that even if the engine light wasn't blinking, the car started but like without enough power and then it stalled, I tried again, and it has always started OK the second time.
3. A couple of times, I was on the road and stopped the car in a red light and it stalled when I switched to neutral.
4. The car sometimes struggles with the first gear, when I'm switching from neutral to first gear to start the car (after being stopped in a red light for example). The car would start very slowly, even if I'm pushing the accelerator and don't have my foot on the clutch anymore. But after few seconds, the car runs well and I switch to second gear, third gear, etc. and runs perfect. Above 10-20 km/h the car runs perfect, I only have issues (sometimes, not always) at very low speed in first gear.
I think that's it. So far, my mechanic has checked the code problem and he coded a new key, thinking that it was a communication problem between the key and the engine, but it didn't solve the problem. I don't know where to bring the car, because every time someone checks it, they can't find the problem or a solution and I don't want to spend more money for no reason. But I'm also worried that the car breaks down one day in the middle of the road or when I'm in the field with volunteers (I need the car to do field work, but luckily it's not a remote area.

I notice it happens driving between 20-30 mph and accelerating very slowly. Rpm around 1500. The tranny changes gears up to to 3rd or 4th gear and the vibration starts. If i accelerate, it goes away. During quick acceleration I never notice this vibration. Also if I drive the car in manual and go thru the gears i never notice the stutter. The problem feels like driving a manual car in a higher gear at a low speed and need to downshift.
