Replying to: hewhohesitates (Oct 14, 2009 6:13 pm) 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.)

Replying to: hewhohesitates (Oct 14, 2009 6:13 pm) 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.
