scroll down to the bottom and it has all the available transmissions for supra with their gear ratios and the rear end ratios that they came with and it says for the tt auto 3.769. This is the rear i plan to use also because the 5 speed sc300 has a short first gear and this makes it a little bit longer and useable once you go na-t.
