Is the Sienna platform shared with anything else? - Toyota Nation Forum : Toyota Car and Truck Forums

Does anyone know if the Sienna shares the same basic platform with something else like a Camry or Highlander? After running into problems trying to get the tranny pan off of my 2007 Sienna, I was hopping to get some tips from other forums.

Sienna platform is a version (albeit highly modified) of the Camry platform.

The first gen Sienna was based on the Camry platform. The second gen was based on the Lexus RX330. This enabled Toyota to offer AWD as an option.

Yes Highlander forum has a write-up on the tranny boolt removal.

Thanks for the info, shortlid. I found the tranny pan thread and my suspicions were confirmed. Looks like I should be prepared to remove a couple nuts from the tranny mounts and jack the tranny up. It shouldn't be this way.
