This is stock trans that came behind my 1jz gte vvti when i did the 1st swap into my 1st gen 4runner. Outside casings are extremly similar, internals to carry mild upgrades for the 1j and 2jz motors. I would consider mating the two together to turn this into a 4wd trans. But i really wanna keep this as simple as possible and currently the ecu i have for the 1j going in will not support this trans :(
