Hello Eric, I have the 2007 v-6 SE I have had the valve body replaced then the Trans. The flare problem still existed.
  They then had my car in for service and said couldn't find the problem. However when I got the car back the flare was gone and has been gone for 6 months now. I have strong reason to believe they went ahead and reprogramed the ECU with the latest TSB and didn't want to tell me so they don't have to count it as a fix attempt and they protect themselves
 from possible lemon law buy back.
  I happy the flare is gone but the trans does not shift smoothly and has a downshift problem in 1st and 2nd gear.
  My Gas mileage has also dropped and I get no where near the MPG I should be getting.
 
  To say the least this experience with this car has been my worst ever!
 
   Keep in touch, Chuck

4th to 5th gear flare by ericlsailor

I have now experienced a flare from 4th to 5th gear. It seems unrelated to the cold weather. The other lower gears appear to have some slippage and some not so smooth shifting. After the TSB was applied, I notice that the 3 to 4 shift holds longer than it used to and when cold, it takes up to 3000 rpm before it shifts.
 
My original problem with slippage in the first gear has not continued and I am sure it has to do with the weather getting warmer. I have an appointment for the flare issue which may be easier to replicate as it seems to happen each time.
 
Has anyone heard if Toyota has issued any kind of statement about the transmission problems and a once and for all fix for the problem?
 
Eric

Ha! That explains it! I couldn't figure out why, when I asked the dealer to do the latest ECU software update for the infamous 4-cylinder shifting/throttle response problems, they refused. But then, they did the update (very obvious improvement in drivability), and told me they hadn't done it (see post 739 in this thread). Thank you Chuck28.

Transmission hesitation by totoman

I own a 2007 Toyota Camry LE, and have concerns about the hesitation when excelerating. It can occur from a stop sign, merging into traffic, or changing lanes at higher speeds. During city driving if I let off the excelerator at say 40mph, then try to reaccelerate, it hesitates as well. I'm not sure if that deceleration and reacceleration are clutches actually slipping, or if it is the ECM trying to keep a soft shift. And get this........when I mentioned it to the salesman during the demo ride, he said that the accelerator has a computer that monitors each driver's habits, and that in two weeks it will adjust to my demands on the engine. I had a trouble-free 1996 Camry, so I had no reason to doubt him.

Lesson...
 
Never, NEVER, talk technical aspects with a salesperson, that is unless you are the one "directing" the conversation. And ten to one odds say the salesperson will get it entirely wrong when relating it to the next person.
 
Toyota has eliminated an important part from their transaxles and that required them to use DBW, E-throttle, to delay the onset of rising engine torque for certain fairly common driving situations(***). So DBW is used to make it "easy" on the transaxle clutches at certain times. Say when a downshift is required but cannot be quickly accomplished due to the "abolition" of the transaxle component and therefore the loss of its functionality.
 
*** Driving situation/circumstances described quite adequately in a TSB issued for the Camry in the spring of '03.

Totoman,
 
There is a software update (TSB - Technical Services Bulletin), which the dealership can apply free under warranty. It makes substantial improvement in power, driveability, and cruise control smothness. It's been previously posted in these forums.
 
It takes about 1/2 hour for the dealership to reload the ECM software with the upgraded release, no big deal. Runs great.
