5th & 6th Generation (2002-2006 & 2007-2011)Toyota Camry Discussion for years: 2002-2006 & 2007-2011
Topics of discussion range from fuel economy, safety, modifications, performance all involving America's favorite family car, the Toyota Camry.
ANYONE TRIED CHANGING TRANSMISSION FLUID TO A HI PERFORMANCE AFTERMARKET ONE TO SEE IF IT HELP IN THESE PROBLEMS,READ ONE POST THAT TRANSMISSION FLUID TEMP WAS A PROBLEM UNTIL WARMED UP . ANY INPUT 6CYL SE PEOPLE.

The Camry uses a WS type fluid.
$42 a gallon at Toyota.
I know Amsoil doesn't make a compatible fluid.
and the service advisor told me , people arent use to driving a DRive-by-wire.
He's right! Sort of... There is a diff between a cabled car and DBW, the DBW being more sensitive and having a multitude of additional "modes" based upon the various inputs from all the different sensors.
BUT - the shift flare problem is NOT caused by inexperienced DBW users... Further, fluid will not change the condition, especially full synthetic because it is thinner. The problem is the result of a faulty check valve allowing fluid to drain causing a "bubble" in the valve body... As the trans fluid builds pressure, the bubble isn't release and when the trans calls for 3 to 4 shift.... BBBBBUUUUUURRRRRP! You get shift flare.

Hey, you figured it out. Now aren't you kicking yourself for taking it in the shorts. If you had only waited a few weeks.

Very interesting. I'm curious, how do you know this is the exact cause? It sounds reasonable though..

Unfortunatetly for whatever reason, there's still the difference whether the valve body fixes the issue or a check valve.. I'll have to look closer at the workings of the valve body... It may be that prior 07/06 builds there's an issue with a solonoid or something. Post builds may have introduced the check-valve problem which may be deeper than a valve body.

This was the rationale provided as to why my transmission was not a candidate for the TSB as originally written but instead called for replacement as it was built after 07/06.... When I get a little more downtime I'll look through the FSM and see if I can locate more precisely what was described.

Thanks for the answer.
The burning question for me remains, is the 6 speed transmission inherently flawed? Are there different revisions, some of which show the flare problem? Are there units that cannot be repaired, others that can? Are there any V6 models that don't have any flare problems or shift problems in general at all?
I'm gonna be a nervous wreck when I pick up my new car.

LE V6, 8000 miles no major problems...I did notice a shift flare around 4000 miles, very minor, only a few times. I have tried to make it flare, hot, cold, slow, fast...could not duplicate the flare. I drive it in various ways, and run it hard a few times a week.
I am starting to like my Camry more and more..I hope it holds up!!!

Excellent explanation! Why hasn't Toyoi. figured this out? Seems simple to me.
