I'm sure this has been covered somewhere, but for the life of me I couldn't find it using the search function so please forgive me if this has been covered. I want to 1UZ vvti swap my Altezza, but keep the 1UZ vvti automatic transmission. I've seen people talking about this being possible, but I can't figure out which auto 1UZ tranny fits in the Altezza/IS200 shell. Any leads or info would be greatly appreciated. Thanks for your time .
