if it were just a few of us with transmssion problems, toyota would not have issued a tsb or modified their brand new transmission 3 times in less than a year to correct the problem. they would have just popped in the same new tranny and we'd all be good to go.
can't speak for the rest, but i love my camry despite the flare and am sure it will be corrected in time.
Anyhow Happy New Year to all!
The local dealer has a meeting with new Camry owners on Jan 10; I may go and see what they say.
Anything "learned" about individual or personal driving habits, styles, should be erased each time the vehicle is started, and according to the engineering white papers I have read that's exactly what happens.
Otherwise I would rather hate for my wife to be the follow-on rental customer for Kyle Petty.
that's interesting... can you be more specific?
"The poor response you described typically surfaces either when the accelerator is depressed fully to the floor or when depressed in an aggressive manner. The newer version of the Camry has transitioned from a manual throttle linkage to an electronic throttle control system. The electronic throttle control monitors the everyday driving habits of the operator and then tailors itself to make the most efficient gearshifts. On rare occasions when the operator fully depresses the pedal or depresses the pedal in an aggressive manner, the system may experience a delay in determining how to make the optimal gearshift.
At this time Toyota has no plans to make changes to the shift characteristics of the transmission. To minimize this condition, we recommend trying a firm yet gradual application of the accelerator.

Toyota Customer Experience”
A week later a TSB was published as a fix to the imaginary problem. The TSB helped but did not cure the problem. If you call the 1-800 number At TCE they say there is no problem with the transmission and we can of no further assistance to you! What a company!!
Hopefully Toyota will resolve this problem so everyone who is dealing with this issue will be able to completely enjoy this really great automobile.
It is neither necessary nor appropriate to tell people that because your experience differs from theirs, they are wrong in what they report.
I'm quite sure from everything I've read about the 07 Camry that the largest majority of owners are happy and problem-free. But it is a fact that some are having some problems, some of which are very serious, and they are entitled to discuss them here without enduring insinuations that they are being less than truthful.
By the same token, those of you who are having problems need to accept that not everyone has the same issues you do. If you find you need to tell someone ("female" or not) they are having a transmission issue, it's extremely likely that's because they are NOT having a transmission issue.
In other words, no one should assume his or her experience with the 07 Camry is everyone else's.
Let's try to keep that in mind, okay?
Now, let's allow this discussion to focus on being helpful to people with problems. Those who aren't having difficulties, please say thank you and visit the main Camry group to find other discussions of interest.
Thanks.
wwest, you didn't get that out of any automatic transmission engineering white papers regarding "fuzzy logic" cumulative learning. (It's called "cumulative" for a reason... ) And yes, multiple drivers will result in some intermediate shift response characteristics not to the liking of one or all drivers - particularly if one of the principle users drives like a grampa and the other at the opposite end of the spectrum drives like a boy-racer in a hurry to get to his own funeral. To erase the "learned" shift quality parameters in some cases involves something as simple as disconnecting the negative battery cable. In other cars, a scan-tool has to be connected to the OBD-II port and programmed out through a specific instructional routine - but it's NEVER automatically done.
If what you state were true then why do the many more expensive and/or upscale vehicles that can recognize the various, different, key codes used by each driver not state something in line with the need to not go randomly swapping keys?
Now, given the wide and diverse demographics of this market can you think of even one good and valid reason that personal driving styles or habits should be retained beyond the point of shutting down the engine?
To the contrary, the white papers I have read indicate that these systems begin to learn the driver's unique style or habits as soon as the vehicle is put in motion and within a very short period the driver has been "binned" into 1 of 4 categories. A short time later the driver's style is further resolved into 1 of 16 categories and thereafter the driver may actually be rebinned should the system note a change in style.
A rental Camry? I'd not like to imagine what it could mean.
I wonder why they try to have it learn how you drive. People learn faster, and I really can get used to anything, if it's predictable. The hesitation would be less annoying if you could count on it. Sometimes, I hit the gas and I get an alarmingly fast response. Followed by a panicked braking, of course.
They make a lot of money if they persuade you to go back to them for service, so it makes sense to do this.
"I'm quite sure from everything I've read about the 07 Camry that the largest majority of owners are happy and problem-free." The few available articles that I have read indicate that the Toyota recall rate has increased 41 times (not percent the last two years.)If they had 1000 recalls 2 years ago they have 41000 recalls now. It is hard to get accurate local news about this because if a local paper prints bad news about an automobile company they lose a bulk of their advertising money.The next time you read a paper look at the number of pages dedicated to auto advertising. PS I knew you were not going to let that comment about a female slip by!
I wish I had seen this forum before buying, it really would have persuaded me to buy American again. This is my first and last Toyota!!!
As of 1/3/07 NHTSA's website contains 32 complaints specific to 07 Camry transmission issues. These complaints are listed across 3 separate "transmission" categories. I did not read the details of each complaint so it is possible that some posted complaints may reference some other transmission or driveline topic.
Interestingly, there are no complaints filed on NHTSA's website for Lexus ES350 transmission problems. The V6 Camry and ES350 use the same transmission.
The ClubLexus forum does contain 2 discussion threads for ES350 transmission problems. This specific posting contains some interesting insight into the problem, and hopefully the fix.

I just saw where Ford has adopted a variable displacement ATF oil pump for the new Ford Edge and I suspect its to fix this very problem.
2014 Malibu 2LT, 2015 Cruze 2LT,
Most Toyota transaxles have the O/D locked out until the ATF is WARM, then it will upshift into O/D.
Mine takes up to about a 1/4 mile on a cold morning.
But that's an upshift so who knows..??
Took the car to dealer (jersey city).
They Recaliberated ECU ENGINE AND TRANSMISSION (PER TSB#EG056-06).
Then was advised the car would be sluggish for about 10 to 15 miles then it would be ok.
Also, the mechanic said "your car should be much better now but there will always be hesitation....it's normal".
Drove the car 25 miles to confirm that hesitation when pushing the accelarotor while on 35 or highr speeds doesnt increase the car's speed.
Called dealer again and they were more than eager to help.....will see what happens when they check the car next week.
Also! I test drove a camry LE at another dealer and found out the car got the same problem.
So it looks like a defect in all 2007 CAMRY LE.
Needless to say, this condition in the wrong situation can result in severe injuries and even death!
I think at this point it may be too early to file a complaint re this defect to NHTSA (http://www-odi.nhtsa.dot.gov/ivoq/).
Must say service dept of Toyota at jersey city is very responsive.
Please share your experience.
Thank you

Ford has just announced that the new Ford Edge has a variable displacement ATF pump which I strongly suspect is being adopted to solve this very same problem as is being reported for many of their FWD vehicles.
Knowing how the "standard" fixed volume ATF pump is constructed within most automatic transmissions it is hard for me to imagine how it might be easily converted to a variable displacement pump.
Were it me I would look into adding a small accummulater pressure storage tank much like the one used in the ABS pumpmotor assembly.
Adopting a variable ATF pump would very likely mean a complete and total redesign of the transaxles and that might be an explanation for why Toyota has not yet come up with a satisfactory fix.
with the linkage being mechanical, the throttle is going to open and close with the accelerator pedal. and if the gas doesn't increase when the pedal is pressed, and the throttle is opened, then you can go too lean and stall which is a no-no and safety problem in and of itself.
isn't DBW fun fun fun?
Aside from class action suits...I thinke if all of us make it a point to RATE the CAMRY LE in as many places as possible...this might help.
By the way, any suggestions as sites where we can rate the camry to reflect this serious problem?
NO!!!!!!!!!!
First, the only Toyota I own is a Prius.
But I do have a 2001 AWD RX300 which exhibits the earlier symptoms resulting from the revised shift pattern/schedule adopted late in the last century as a safety measure. Seemingly on all Toyota, Lexus, Ford and VW FWD vehicles with automatic transaxles. At least those are the marques wherein complaints of 1-2 second throttle lag or downshift downshift delay/hesitation problems can be most easily found.
My solid suspecion is that sometime late in the late century, say 1995, the automotive insurance industry approached the automotive manufacturing industry with the news that statistically FWD and front torque biased AWD vehicles were proving to be dramatically more hazardous(***) in foul weather conditions than their RWD and rear torque biased AWD counterparts.
The obvious message being: "either fix what's wrong or we will start charging a premium to insure FWD and..., vehicles."
Another obvious point along this line is like the over-confidence drivers of 4WD/4X4's get in foul weather so do many FWD owners due to the extra traction provided by the engine weight being over the driven wheels/tires.
But that wasn't the major issue.
Engine compression braking on a FWD vehicle can have a really adverse affect on vehicular control on a slippery roadbed surface. Even more to the point the anti-lock braking system can be made non-functional due to engine compression braking.
So nowadays almost all FWD and front biased AWD vehicles with automatic transaxles will UPSHIFT upon a FULL lift-throttle event. That leaves you in coastdown mode in to high of a gear ratio should you suddenly have need for quick acceleration.
Because the engine is now at idle and with the trnasaxle having just completed an upshift there is now insufficient ATF pressure/flow to complete the required downshift quickly.
So the manufacturers have chosen to use DBW, e-throttles, to delay the onset of engine torque developement until the downshift can be completed.
*** Ford Motor Company has just been awarded a patent for two techniques which appear to directly address this issue. The first of these involves substantially reducing the level of regenerative braking on a hybrid vehicle when the OAT declines close to or below freezing. The second involves disabling regenerative braking the instant the anti-lock braking system activates so as not to interfere with ABS activity.
The only vehicles in production to which Ford could currently apply this patent are both FWD or front torque biased AWD.
This isn't directly related to the topic at hand, but I had to respond to your comment. There is NO evidence that front-wheel-drive vehicles were involved in a greater frequency of crashes in inclement weather conditions compared to rear-wheel-drive vehicles. Therefore, the insurance industry never approached the automotive industry demanding changes.
If there were such evidence, there is no doubt in my mind that the research arm of the insurance companies, the Insurance Institute for Highway Safety, would have publicized a study to that effect.
If you can provide a link to ANY research showing FWD vehicles are so dangerous in bad weather, I'd like to see it.
That said, it is the Camry that has been the best selling car in the US for 9 of the past 10 years, not the accord. Should you be interested in the Camry, and are looking at the I4 5A, just make sure it's built after October. As for the V6 6A, I'm still not aware of anyone with one built in the past few months that has reported the RPM flare.
Can you spell "parasite"?
Can you imagine what would happen to FWD automotive sales, let along used car values, assuming what I surmise is true and the information became publically available from a source considered as reliable as the IIHS?
"...There is NO evidence...."
Not only does the Ford patent speak strongly to this issue there is clear and certain evidence that Toyota, Ford, and VW have "stuck to their guns" in the face of fierce public outcry about the adverse affects of these 1-2 second downshift delays. Why wouldn't they simply revert to the old tried and true shift pattern/schedule?
For Toyota it seems to have begun with all the reported premature transaxle failures in the 99 RX300. The most real indication of this being a problem was with the 2003 Camry transaxle as recorded via the TSB issued in the spring of 2003. And as you can see those exact problems continue with the 2007 models.
Eight years is an awfully long time for Toyota to take to correct a design problem.
Don't we ALL know that these transaxles used to downshift upon full lift-throttle events? Other than the aforementioned safety issue why such a drastic change in the shift pattern/schedule and seeming only for FWD models?
Because anyone having ever driven a stick shift FWD vehicle on adverse roadbed conditions knows full well the hazards of downshifting to slow or stop. Best to use the e-brake lightly.
It reminds me of Toyota's attitude with the "oil sludging" problem. Toyota blew it with their somewhat slow response of even acknowledging the problem. Seems like history is repeating itself again. Sad too.
What's happening with the auto industry of late. Why can't any company just produce a trouble free product that anybody can afford to buy & own? I'm at a loss on this question...!
The Sandman :mad:
The evidence is out there. The dealerships know of the problem. There is definitly a transmission problem with their new line of Camry's. Most importantly, the transmission issue is an extremely dangerous safety issue for all of us. We all need to bond together and start writing letters to Toyota, continue giving bad reviews to the new Camry, complain to the National Institute for Highway Safety, write letters to our senators and congressman. We need to force a transmission recall among Toyota and place pressure upon the company. Thousands of people read this forum and Toyota has a team developed to read our posts and figure out how to do damage control through the press.
If Toyota will not issue a safety recall for the 2007 Camry transmissions within the next 4-6 months, a class action lawsuit will have to be formed and will be available to all 2007 Camry owners.
Then you said, You can be certain sure that the automotive insurance industry is just as "beholden" to the automotive industry as are the automotive magazines and your daily newspaper.
Can you spell "parasite"?
So which is it? Is the insurance industry able to stand up to the auto companies and say it's time do something about these "hazardous" front-wheel-drive vehicles? Or is it a "parasite" that feeds off the auto industry?
All your statements about how automatic transmissions upshift, downshift, and hesitate are beside the point. Where is the evidence that FWD vehicles have been "dramatically more" hazardous than RWD vehicles in bad weather conditions? Can you point to higher fatalities and injuries? No, all you can cite over and over are Ford's patents which deal with regenerative braking, which is used at present only in hybrid vehicles.
This is my last comment on the issue, although I find it curious that if you think FWD and "front torque biased" AWD vehicles are so hazardous, why do you own both a Prius and a Lexus RX? Shouldn't you be driving a Crown Vic and a Tahoe instead?
Now, let's return to the topic at hand, before the hosts step in and ban this side thread.
Agreed, there is no SOLID evidence that FWD vehicles are more hazardous in wintertime foul weather conditions, and only past history leads me to believe that the insurance industry has gotten involved.
So, I hereby revise my statement as follows...
My solid suspecion, based on the purely circumstantial evidence before me, is that sometime late....
