Lexus LS 2007+ :: LS460 Transmission Would Shift Hard And Jerky Almost Through First 3 Gears
Feb 3, 2014
So I recently purchased a 2007 LS460 with 115k on it. I've noticed that about a month ago the car started driving pretty weird. The transmission would shift hard and jerky almost through the first 3 gears, like driving a manual.
Also, when I tried to floor the car from maybe 40-50mph, the rpm would shoot up only 500 then downshift and accelerate causing a violent jerk. It feels like if I was driving at 50mph on 8th gear, when I floored it the car would feel like it downshifted to 7th gear for merely less than a second and downshifted again to 4th gear causing the car to jerk hard.
This is the car's history:
- Reset the ECU by disconnecting the battery (no luck)
- Auto transmission software has been updated at the dealer
- Valve springs recall has been completed
- Head covers has been changed
- Engine module has been reprogrammed by the dealer at 70k miles
- Trans fluid has been changed at 70k miles according to lexus.com service record
So at this point I really don't know what could cause this problem anymore, maybe it could be the transmission fluid?

The area where you shift transmission gears isn't lighted. Find that strange even though you can see what gear you're in on the lighted panel. Gear not the right term, but think you know what I mean.

2009 Kia Sorento. The Transmission was replaced twice last week and the week before. For the same problem. 50K miles. Auto Transmission...
I have a hard shift between 3rd & 4th gears, I have had the transmission replaced twice. Could it be something else?

I have a 2004 manual transmission Santa Fe. I've maintained it very well since new.
About 6 months ago I noticed it was getting difficult to manually shift gears. It wasn't grinding or anything, just "hard" to get it to go into the various gears while driving. Before, I could shift into any gear with just 2 fingers on the gearshift and it was smooth as silk.
I went in and had the gear oil changed. This was something I didn't even know needed to be changed and the guy said most people never do. They showed me the oil they took out and it looked more like black water than oil and smelled kinda funky. They changed the gear oil out, but still no difference, and in fact it's getting worse.
The best way to describe it is the only way I can really shift gears now is to find that "sweet spot speed" where the gears will change on their own (so to speak). I find it particularly difficult going from 1st to 2nd, such as when starting from a stop light. People almost rear-end me now as it takes me longer to get it into 2nd gear.
Once in gear it runs perfectly, no problems. The clutch seems to be working normally, except perhaps while stopped in 1st gear, it sometime seems to jerk a bit, and I find this most noticeable if I'm stuck in very slow moving heavy traffic with the constant stopping and then moving forward slightly and such.
It is almost impossible to "gear down" into a lower gear unless I'm at the speed where it would normally go into that lower gear on it's own. The best way to describe it is how it is possible to drive a standard transmission car WITHOUT a clutch if you shift at just the right time/speed. But I DO use my clutch, but if I'm not close to "that speed" it's really, really difficult to force it into another gear, and the few times I do try and force it, I'll often get a bit of grinding.

I went on vacation for a week and left my car at my parents house. I came back and now it has become extremely difficult to shift between gears. It's nearly impossible to get the car into reverse, extremely difficult to get it into first, makes a thud when pulling it out of first, is semi difficult to get into 2nd, but only a mild nuisance to get into 3rd through 6th.
For more information, the car is a 2012 Volkswagen GLI with just shy of 40,000 miles. The car ran just fine before I went on vacation and the car was not moved while I was on vacation. I did notice that a little ticking kind of sound when I had the car in neutral with no clutch. So the throw out bearing was starting to wear, but it was a very slight. But I haven't had any other problems.

So I changed transmission fluid on my 1.8t GLS because I was having difficulty shifting out of gears on cold starts. It seemed to work fine for a few days and now I'm back to square one, it still doesn't want to shift correctly!

I have purchased LS 460, 2010 with 21000 miles on it. Dealer said he put new Kumho tires on it. But the power steering feels hard, and is not even as soft as my Honda Pilot 2009. I have made an appointment with Lexus dealership for this concern ( I had the vehicle checked by Lexus store before purchasing.) I have read good reviews about Michelin tires, am wondering perhaps I need better quality tires. Do not know what the dealer is going to recommend.

I purchased my first Lexus in October, a very clean 2009 ls460. In colder weather (for Tucson AZ) in the 30's to 40's I notice that the transmission slips while the car is accelerating between 2nd and third gear.
By slipping, I mean as the car shifts between 2nd and 3rd it feels like it goes into neutral for a half second, so rpms spike 500 rpm, the car stops accellerating, and then catches as the next gear is finally engaged.
It does this pretty much every day when the car has been sitting overnight on the first steady acceleration after backing out of the garage. It only does it once, subsequent shifts a re pretty much normal.
Every once in a while coming out of a parking lot after say grocery shopping, it will do it again, just once.
I dropped it at the dealer and they of course could not replicate it.
I made a youtube video which shows it sort of. besides the rise in engine rpm, you feel a lurch in the acceleration as it drops down into gear.
Service records showed the trans was serviced just before I bought it.

Well, i have almost had it with this car. When the car is idling in park... ti sounds like the transmission is chattering,... then, once i put it in gear it gets louder. like a medium fast "clinking" noise. ALSO, when rolling at a slow speed and i barely hit the gas the transmission (or maybe engine) makes a zipping chattery noise.

My 2009 Accent started doing the Hard/Jerky shift problem that I seen discussed in the forums. Had check engine light, scanning showed a code P0717. My question is, which sensor should install?

Lately I have noticed that the transmission is not shifting smoothly in the lower gears. I have 114K on there. Spoke to my service manager and he mentioned that it may need calibration. Doesn't sound right after all the miles?

After driving around hard for a couple minutes I got home and the car smelled like something is burnt then I went out to drive normally to get the smell out but didn't work. Then I realized my gears were hard to move into especially 1st, 2nd, 3rd. Its hard to change into those gears now. what could be the reason? What do i need to do for my gears to move smoothly again? I just got this car, my first.

We are having issues shifting the car it is hard to shift into gears. I have replaced the transmission and the clutch, trans mount is still good all mounts for that matter are still in great condition its getting tiring to have to slam the car into gear all the time.

My 03 Gli 24v manual transmission has been acting up lately. First it started to get a little difficult to shift into gears about a week ago. Then tonight i was driving through a parking lot in 2nd, and after i came to a stop i tried to put it back in to first and it would not go into gear. As i was trying to get it into 1st i could tell it was grabbing a little bit and the car was inching forward.
I got it to a parking spot and starting reading about other peoples issues, one i read said they were able to get it to move after pumping the clutch some. After trying that i was able to get it into gear and drive it to my parents. Looked at my brake fluid and its full. Took it for a test drive around the neighborhood and it was shifting fine at first then started getting a little difficult to shift again. I tried taking off in 6th and it stalled. I tried going from 1st around 3k-4k rmps to 6th and it was still driving with very little lugging. My clutch feels and is still stiff, not loose at all. I do have to go all the way to the floor with the clutch before im able to shift
Finally to my questions. Could my clutch be going bad? Could my cables need adjusting? Something I read about a pressure plate maybe?

I own a 2002 Monte Carlo SS 3.8 6cyl. I believe it has a 4T65-E transmission.
On a regular basis if I drive 20 miles out of town, on my way back the transmission starts to shift hard (long shift?). From my research online, the 4T65-e is a faulty transmission to begin with. Is it worth replacing the Shift and Pressure solenoids? If I were to buy a new transmission where should I look? What are some model numbers?
Oil, trans fluid, filters are changed on regular basis.New catalytic converter. No Check Engine Light.

I've got a 2003 Xterra, RWD, manual transmission, with around 110k. It's been giving me a little trouble shifting into gears 1-3 when the weather's below 30F. It started doing this when I got the transmission fluid changed last, about 2 years ago. I took it back to the mechanic who fixed it immediately, and he changed the fluid a second time for free, but when the problem persisted, he said he had no idea. Needless to say, I haven't gone back to him. Since then, I've tried to ignore it (not too hard in sunny NC), but it's getting worse and I'm about to move to Chicago, so I think I should fix it before I move to the land of harsh winters. My first guess would be the tranny fluid weight might be a little low and I should try a heavier weight.

I have a 2002 ford ranger edge. swb, 3.0L, 5spd. I have been noticing it is getting harder to shift gears, put in 1st at a stop light lately. There is no grinding just seems harder to engage. Checked fluid level and it is clean and full. Recently i have developed a vibration under power. Let off the gas and smooth as can be, apply throttle and starts vibrating. Not sure if flywheel is "hot spotted" or perhaps broke a spring on pressure disk. Just seems odd it's only under throttle. Yes already checked rear end and U-joints.

So I just purchased my new-to-me, CPO 2010 RX 350 two weeks ago. It had 81,750 miles when I purchased it, and it now has about 83,000 miles. I just came back from a weekend vacation, having driving about 500 miles total. This morning when I turned on the car, I noticed a message saying "Check AWD System," the check engine light was on, the general warning light was on, and the traction control light was on. As I was driving, I realized that the car wasn't downshifting properly. I didn't drive faster than 40 mph on my morning commute. When the car did downshift, it was a hard, jerky shift.
I did some reading on the forum, and many people suggested all the warning lights could be fixed by taking off and retightening the gas cap (due to the vehicle not reading the emissions properly or something?). I also read that topping off and overfilling the gas tank can be cause for the warning lights to go on. I did fill up once on my way home from my vacation, and haven't filled up since.
Anyways, I just now tried to adjust the gas cap and then restart the car, but the warning lights are still on. What I should do or if I should drive it a bit to let the emissions build up again? My problem is is that I live about 6 hours from a Lexus dealership, so I'm trying to figure out if I can resolve this on my own or what I should tell a mechanic specifically if I need to take it in.

I've got a 2011 lexus es350 with a bad transmission. I purchased the car 4 months ago with 50,000 miles on it. I noticed in the carfax that the transmission fluid was changed at 25,000 miles??? I knew that wasn't normal. After having the car for 4 months i noticed the transmission would shift rough in the mornings. I took it to lexus and they added more transmission fluid to the tranny. After I got the car back it had no getup and go. And the car would stutter when revving at high rpm.

I've been having problems with my column shifter ever since I installed a Pioneer shift cable probably about 3 years now. I was told and also thought that the cable would loosen up after awhile but it never has. I had some put it on and I watched him do it. He seemed to have some trouble because it took him a long time under the dash. It shifts so stiff that over a period of about 2 years it finally broke the end of the shift tube one night. Luckily I was able to fix it the next day by getting a spare without missing any down time. It was still just as stiff with the other shift tube. It finally broke the plastic on my shifter tonight, not necessarily whatever is causing it but because it takes so much effort to shift into Park, Reverse or Drive.
I think the plastic may have cracked over time. Luckily I had another one at home along with another shift tube. I didn't replace the shift tube this time but I did remove the caps and smear some grease on the bushings to see if it would make it turn. I looked further down at the end cap that broke last time and sure enough one of the bolts was backed almost all the way out. I retightened it tonight too. That's what happened when the bottom broke last time. One of those bolts backed out and it cracked the housing. It works now but if you go all the way to 1st to get back to anywhere it really takes a tremendous amount of effort to get it to shift. Something is not right and I cannot pinpoint it. I know they offer brand new shift tubes but I'm not sure if that's the problem.

This is on my 7.3PSD. I've observed that the 1-2 gear shift drops about 1,000 RPMs and takes a good half second or longer to do so when given a lot of accelerator pedal input. And then the 2-3 shift is a very quick and harsh shift.
If I am accelerating gently the 2-3 shift is as unnoticeable as the 1-2 shift is quick. Is the slow 1-2 shift causing the trans to protect itself and affecting the 2-3 shift? And if so, what do I do to resolve all of this? I changed the trans fluid a week ago and there is no change.
