Lexus ES 2007-12 :: Transmission Slipping - Car Will Rev Up With No Acceleration
Feb 19, 2016
I purchased a 2007 ES350 from a Toyota Dealership (64K, now has 66K). I purchased a warranty for the vehicle. Over the last couple weeks I have begun to notice my transmission is slipping - the car will rev up with no acceleration. It will usually catch on the second attempt of pressing the gas pedal. I notice this behavior usually after a cold start in the morning as I am leaving for work.
Before I go into the dealership to tell them about my potentially expensive problem, I want to ensure I go in knowing as much as possible. I have already found a ton of issues surrounding various transmission flairs at varying gears. (TSIB: TC001-06)

In 2006 I purchased a 2004 5-speed manual shift Nissan Xterra 4x4 with 19k miles on it, it looked and ran like new.I live in Florida, during the Summer of 2010 I noticed that when I accelerated from a standing start (like at a traffic light) as I shifted through gears 1-4, at some point the RPMs would rev up but the car was accelerating very slow. The only time this doesn't happen is in 5th gear or in 4WD-high or 4WD-Low. This problem is not consistent, it happens occasionally but enough times that I've had to alter the way I accelerate to avoid this problem, ie accelerate very very slowly.
I have taken my Xterra to my local Nissan dealer, twice, they cannot replicate this problem no matter what they do; drive it cold, drive it hot, fast, slow, cold weather, hot weather, no matter, they can't replicate the problem.
I have read here and there on the 'net (we all know the 'net never lies) that the transfer case on 4WD's can act squirrelly or could even be a simple case of replacing the transfer case fluid.
Why this "slippage" is happening and how can it be fixed? This is of concern only because if I have to accelerate hard (like when a locomotive is looking to T-bone me) I'd like the Xterra to get up and go rather than pause and reflect over the lilies of the field while Thomas the train is bearing down on me.

So, we bought this camry about a year and a half ago and it has slowly developed what I believe to be a transmission slip. It seems to happen more often when the car is cold (prior to warming up to operating temperature). The transmission only shifts between (i think) 1-2 gear. Could be 3-4 but, it's kinda hard to tell.
Anyhow, it doesn't keep us from driving the car but I fear it will eventually make the car un-driveable.
We have a used car warranty but under the automatic trans. section it appears to only cover hard parts and not things like bands or other friction materials.
is this a known issue for this transmission? and if so, what typically causes this kind of slipping?

We have a 2010 Santa Fe AWD LTD with about 140, 000km on it. It recently came back from front suspension work. The suspension is fine now, but we notice harder shifts in the transmission. Also, there seems to be a vibration just before shifting gears and when under load (like going up hill) seems to slip (like on ice) about once every second until the shift is made. Once the shift is made it drive smoothly until put under pressure again. Even stepping down a bit on the accelerator will cause this slipping feeling (or maybe its loss of power).

Just had new plugs put in and a tuneup so it's not that. Could something from the suspension work cause these symptoms?

Car has 67k. It did this before when the car was under 50k. took it in , got it documented and they could find nothing. Last 3 days when I punch on the freeway to pass someone, the car goes in to neutral. Manually down shifting does not work. I had to pull to the side of the freeway today for a few minutes before it would engage. Felt like I was in a very dangerous situation.

My son changed the oil in our 97 Lexus. (It has about 185K miles) The transmission started slipping same day.

My 2009 Santa-Fe AWD Limited is sick! Starting from a stop, the vehicle has abrupt shifts with the transmission slipping (RPM revving). Seems worse when cold. Checked the fluids, and found ATF fluid in the engine oil and engine oil in the ATF fluid. Quick internet check suggest a leaky vacuum modulator valve. (There is no way the fluids went in the wrong holes, the vehicle only has 69k kilometers on it, so it still has original ATF fluid, and I recently changed the engine oil myself.) So, do you think this is the correct diagnosis? How hard is it to change the modulator, and where is it located?

I was driving out of a parking lot and as I accelerated onto the main road my vehicle stopped. I heard a grinding sound and could not go forward or reverse. While the car is in drive, park or reverse my car will roll any which way. It pushed it across the street. I tried to locate my tranny dipstick via visual inspection and manual. I could not find it. Could the stick have never been put back at some point in service and caused this issue. That seems unlikely but the thought occurred. Could it be the velocity joint? Whatever it is it certainly sounds like a transmission issue.

While driving around with the 8 speed is350, It seems like the transmission is slipping when changing from 3-4-5 under light throttle. The revs shoot up and then it finds the next gear kind of like someone riding the clutch in a manual car.
This used to happen a little during the winter on cold start but its happening more often even in warm weather. Maybe I'm just crazy but I'm sure its not supposed to be acting this way.

I have a 2008 RX350 AWD with only 500 miles on it so far and I am starting to get concerned about what seems to be excessive slipping or a delay in response in the trans. Under normal forward driving the trans seems to shift very smooth. The problem occurs under situations where I am coming to a near stop, basically coasting, and then have to accelerate again to continue forward. This could be in a slow moving traffic type situation or when maneuvering through a parking lot. When I try to execute a small increase in speed the engine revs but the trans doesn't respond.
It's as though it's in neutral and unable to decide which gear it should be in. After a 2 to as long as a 5 second delay it finally engages and moves forward. The condition is even worse if I am heading into a slight incline. Once it is engaged everything is fine and the subsequent shifts are very smooth. When starting from a complete stop it works perfectly. I've never had a transmission slip this much in any vehicle. There was one situation where I was almost broadsided because the RX delayed in moving forward.
I realize this is a subjective call but I am trying to determine what level of slipping in the trans is considered normal under the conditions I've described. I have searched and read past threads about issues with the earlier model years but I thought they were resolved by now. I haven't taken the RX in for service yet but I fear I will get the standard - everything is working as designed - answer from my dealership.

I live in an area where we don't really get any snow, very rare. But when it does, everything shuts down because our city doesn't have the proper equipment (salt, plow trucks, etc.)no one here owns snow tires, and we're all inexperienced. It snowed today around the same time as the drive back home and it took forever because it was rush hour at 5:00 pm (Fairly populated city, around 440,000 people).
Needless to say almost everyone was going super slow, 20-25 mph. Couple of people in SUVs were going fairly fast, but generally everyone was being safe. I saw a couple of accidents but nothing too crazy. I had never driven in the snow before in my LS460L. WOW. that was a stressful and long drive back. What normally takes me 30 minutes to get home took me close to 2 hours. While everyone was going very slow, I went EVEN SLOWER because of how nervous I was.
I felt like I never accelerated too fast or aggressively, and I did slow controlled braking (did not slam my brakes abruptly or anything). Yet every other time where I had to come to a complete stop, the rear part of my car would lose control and slide/slip to one side or another. Again, I felt like I was driving cautiously slow (between 10-20 mph) and did nice and slow controlled brakes. But I seemed to be the only one on the road slipping and sliding when at a stop.
The conditions were pretty snowy, but by no means was it crazy (maybe an inch or two of snow). Something that would be laughable to those who are used to real snow . That was a really scary and long drive. I am glad to be home. and I don't plan on driving my car out in the snow anytime soon.

My dad recently bought a 2011... He says now there is a hesitation on acceleration?? Don't know if it was always like that or not he's owned the used car only a few months.

My tranny slips in drive and od when it is warmed up.It's fine for a few miles when it is cold.Did a quick search and it seems like it might be a bad mlps.
My question is, Will a bad mlps act up all the time or just when it's warmed up? Will a mlps and connector from a 91 tranny work on a 95 tranny? Don't really want to throw money at it if it will need a rebuild.

I have an '07 with 122k miles. There is an issue with the car when I attempt moderate to hard acceleration. I have observed the following behaviors:If I hit the gas hard, the engine will suddenly cut out, almost as if it hit the rev limiter or VSC has kicked in. The engine does not die, it just appears to go back to idle. It is not a miss or stumble. It is a full loss of engine power. If I keep my foot on the gas, it will kick in and out, sometimes so suddenly that it will chirp the tires when it re-engages. It will do this until I let off the gas and accelerate more slowly. It seems to happen when the car starts to pull hard over 3k rpm.
It can happen in any gear, as I have tried playing with keeping it in 1st, 2nd, or 3rd, and have observed the same behavior when I hit the gas hard. It is not pedal position dependent, as I have observed this at anywhere between half throttle and wide open. There are no lights when this occurs. I have held it in this state for almost 20 seconds at times, trying to get a CEL, but nothing happens. I have hooked up a TIS tech stream monitor, and there are no problems recorded. The car runs and idles perfectly aside from this problem. If I accelerate normally, it will run just fine. It almost seems like a fuel delivery problem. Could the pump be suspect, not allowing enough fuel during high demand?

About 6 months ago I bought a '08 GS 350 CPO. Love the car but after a month or two of ownership, on light acceleration 3rd and 4th gears will shudder. The whole car will buck and shake, but if I give it more gas it will smooth out. Doesn't seem to be the engine, I suspect more the transmission. Of course I took it in and they "could not reproduce the problem"... Is this just a normal characteristic of the car?

While driving recently I experienced what felt like continued acceleration when I applied the brake. It was only a fleeting moment, but was scary nonetheless.

I have a 1998 honda civic LX that slips very very seldom upon acceleration. It happens under light acceleration and medium acceleration (I dont accelerate hard enough to see it slip at high acceleration, it might!)
What happens is, the car stops accelerating and simply idles. As the motor idles the car drifts and slows down. I have never done it, but I bet in this state I could come to a complete stop just by drifting if I keep my foot in the same spot on the accelerator. When I change my foot, and accelerate harder, the car wakes back up and keeps accelerating like nothing even happened.
I don't think it is the transmission slipping, because in that instance revs would climb and acceleration would halt and that is not the case. I recently gave the car a huge tune up, here's the list
Valve adjustment
Oil and filter change
Cleaned throttle body and IAC
New distributor and cap (Plug wires aren't really in good shape)
New spark plugs
New air filter
Set the timing
New belts
Cleaned injectors
Cleaned battery terminals
I don't know what could cause this problem! The only thing I have come up is the Possibility a TPS (Throttle position sensor) going bad. The only thing that I know of that is wrong with the car is the exhaust manifold has a big crack in it right before the upstream 02 sensor. No doubt this leak is messing with the cars readings of the AFRs. Could this be part of the problem? It is throwing a code for the catalyst system.

2009 LS460 I have had my car at the dealer a few times for loss of power on acceleration. The last visit which lasted three weeks finally gave a diagnoses. The problem was confirmed by the dealer and the factory reps, a knock sensor picks up a signal that retards the timing resulting in no power, I was nearly run over by a semi the last time it happened. They tried to give me my car back on 7/24/14 with the knowledge that the problem is not fixable at this time but I should drive the car and they will tell me when there is a fix. I left the car at the dealer. I was also told that they had a few others with the same problem that could not be fixed.

I have a 2007 LS460L. Bought it new and have loved it dearly for 6 years now. It now has 70k miles and is under an extended warranty purchased at 50k miles. As a first year model it has had a ton of TSBs done on it.
The problem i have had as long as i can remember is a lag or stutter during medium to hard acceleration. It feels a little like the old turbo lag or like a very mild stutter. It has had the transmission adjusted, had the service manager driver it for a week to try and capture on computer etc. But nothing has fixed it. At times it feels like if you watch the tachometer during these moments you can actually see a bounce (I may be imagining).
I have almost given up and just lived with it. We have tried tranny, type of oil, software tweaks etc.

I have an 08 460 LS. I am experiencing sluggish acceleration. It feels like the car is in the wrong gear and has no power. This is intermittent and most of the time ok. Occasionally it is jerky when pulling out when it has proper power.
