Thanks for all the transmission info that I rooted through before pulling the trigger on this one. I got one of the later VINs that has trans modifications and I am already planning the ATF cooling and filtration upgrades. I was determined to get a Sienna but after finding this van in excellent condition and 84k on the clock I decided it was worth the risk. We love the van so far but I will miss the utility and size of the 1st gen. I hope I don't regret this purchase.
