Hi all,

I have a 2006 Sienna with the 3.3L engine. I am considering changing the transmission due a catastrophic failure of the transmission fluid cooler resulting in antifreeze in my transmission which will most likely ruin the clutches sooner than later.

Are all 2nd generation Sienna transmissions the same (2004 to 2010)? The engine changed to 3.5L in 2007 I believe, but I am unsure about the transmission.

Thank you,
