Latest Toyota tranny f/w fix--->NG!

[eflw1029]

Finally got some feedback from one of the forums and it appears the latest Toyota firmware flash to fix the infamous 3rd gear to 4th gear "flare" did not resolve the problem. Before everyone gets totally bummed out over this I'm hoping Mr Shyvly posts his results. Anyway, here's a snippet as taken from one of the ES350 owners on ClubLexus...
Just got my car back from the dealership this afternoon after the transmission received the flash reprogramming for the flare problem. I quote 07LexusGuy:.......

IT DIDN'T FIX ANYTHING!!

In fact, instead of cold flaring, it flared on the way home after 20 minutes of driving. I'll wait to see if it'll flare on cold start tomorrow morning. So far, I'm not impressed with what I see.

I've finally saved a few of the video files to bring to the dealership if and when I encounter the flare. While my 2007 V6 Camry is still relatively new and I have not encountered this flare I do have some of the worse luck ever and knowing this, my fear is it will eventually manifest itself. For those who have tried this latest warranty fix can you quickly post here so the bunch of us can plan and decide next best steps? Thanks guys!

Yes, I saw this post last night.
Kind of a letdown. :-(
I'm still going to go ahead with my re-flash on Tuesday 5/29.
I only have the once after each engine start 3rd-4th slip (flare), which is relatively minor compared to some, so I'll keep my fingers crossed.
Here's a video of what mine does:

I'll report what happens.

Hello, I am concerned with the transmission flare issue as well. 2007 V6 LE here, purchased back in April 2006.

However, I have not experienced any type of transmission "flare" at all. Overnight cold start, after 2-3 hours of driving, none at all as seen from the video above. So my concerns and questions are:

- Is the trans flare issue affecting all 07 V6 Camry's?
- Are there other owners who have the 07 V6 Camry's who never experience the flare issue?
- If no issue is present, is it still recommended to perform the latest TSB (TSB TC007-07) in this thread?

Thank you for anyone's input

- Small but unfortunate % of 6Spd Tranny cars Camry/ES350

- Never experienced it, so far at almost 16K and counting..... When my tranny is cold, under light and moderate acceleration it will just hold the gear a little longer which is what I expected it to do.

- As they say.. if it aint broke don't fix it. Computer updates for an issue thats not present is only asking for trouble. Obviously mechanically the trannys that are working are fine with the current programming. They've made changes in the code to compensate for this flare issue, thus I wouldn't want those changes with a perfectly working tranny.

It's funny you should say that.
Mine doesn't do that. Instead it usually just tries to shift from 3rd to 4th at the normal warmed up RPM, and I get the flare.

In the minority of times that my 2007 Camry V6 tranny doesn't slip (flare), it will hold in 3rd gear longer and to a highwr RPM before it shifts into 4th.
It reminded me of how my 2002 Camry V6 was, and I wondered if that's what it's supposed to be doing instead of slipping.
It got me to wondering...

One thing that initially came to mind months ago, was whether the logic thinks my tranny is up to temperature before it actually is, and lets the shift go ahead at the lower RPM like when it's warm? Because it either flares, or waits til a higher RPM, delays the shift and doesn't flare.
(This transaxle does have a fluid temperature sensor)

I'll go back as many times as I have too, till they get it right or hell freezes over. The latter will probably come first!

That's a good theory on things.

I know for sure when the cars overall temp. is warmer or warmed up, it upshifts at least 200-300 earlier than when cold. It would be nice to know what the behavior of others with trannys that don't have the flare like mine.

2 cars with identical programs, one car flares and and the other doesn't... seems more like a mechanical issue. The programming is a patch trying to fix it. But what's wierd is that with a new tranny, it still happens. So obviously there's variances in how trannys are built.

To me this seems like good debugging information for Toyota. You should be commended on your insight.

Here's yet a third variation however. My car DOES hold the 3-4 shift a little longer when cold but I DO get the flare. Hmmmm.....

I'm scheduled to go in Tuesday to get the TSB done.

I'm going in Tuesday too.
Will post Tuesday night what happened.
