Hi John, I first read your post in the spring of 2009 because I was experiencing exactly the same thing with my 2008 Toyota Sienna. The hesitation in shifting at low speeds when accelerating after slowing down to turn a corner occurs intermittently but is quite noticeable. I've been back to the dealer several times, have been in touch with Toyota Canada - (last contact was in May 2009 and still waiting for a cAll back - it's October!). There is a culture of denial around this problem that is unbelievably arrogant. I'm very disappointed with the lack of commitment to customer satisfaction. My advice to anyone looking at the Sienna is ... buy a Honda Odyssey. I sure wish I had.
John - If you - or anyone - are still following this thread, I'd like to hear how your situation is. Thanks.

The hesitation coming off of corners is a design issue with the transmission (if it were Microsoft they'd call it a 'feature'). Every Sienna has it and it is not a defective part so the dealer cannot do anything for you. Toyota may re-engineer it in some future model, but don't expect to get the upgrade.
I can reproduce it every time I want to in my van with a hard brake followed by heavy throttle so the behavior cannot even be called intermittent. It is however, very driving style dependent- in my normal driving pattern I rarely see it My advice: brake further back, gently and with an even deceleration in anticipation of the stop so the down shift doesn't occur so close to when you want to hit the gas and the problem will go away (as a bonus your passengers will be more comfortable since they won't be jerked around as much.)

You and "johnsienna" give a very accurate description of the transmission hesitation. This is definitely a problem with the 08. I also owned an 04 Sienna and did not have this problem. This hesitation has become much more noticeable after we reached 20-25k miles. It is intermittent but very noticeable.
The dealer said they can not do anything unless there is a TSB. I am adjusting my driving to anticipate when to lighten the foot on the throttle. Hopefully a bigger transmission issue will not develop in the future. I have been happy with the Toyota Sienna otherwise. How this 08 transmission continues to operate and the service provided by Toyota will determine if we stay a Toyota owner in the future.

This problem just continues to carry on from one model year to the next. My 2009 Sienna is experiencing the same type of hesitations that are previously mentioned. I took it into a Toyota dealer last summer and they claimed they never experienced this hesitation on the test drive but they did a "reset" anyway and suggested that I make sure I keep changing my air filter at appropriate times. They refused to go on a test drive with me. I got the sense that they were aware of this type of problem but chose to ignore it like Toyota Canada prefers to do with this issue.

Toyota is VERY well aware of the transaxle downshift delay/hesitation problem.

If you've read this thread and understand the issue is not regarded as a fixable problem for the dealer why waste your time taking it in for service? I mean if you know every single van has this issue, they can't fix it and adjustment of driving patterns alleviate it and that all the dealer will do is look at it, test drive it, reset it and give it back to you almost exactly as you brought it to them why waste your time?

But it is a "fixable" problem, how and when remains the question so drilling down at the dealer on regular, otherwise free time, basis might well be worthwhile.

If you have free time to spend sitting around at a dealer your time is a lot cheaper than mine. More power to you all- I couldn't do it.

Shortly after we bought our 2004 Sienna van XLE AWD, I experienced this hesitation issue incessantly. I solved it by starting out in 3rd gear, moving to 4th for around town, and drive for faster speeds. It works beautifully though some who are with me don't understand.
