So i've done a bit of searching on this and it seem that every thread I find has a different answer. What does it take to put an auto TT trans in my 97 sc300? Is it possible with the stock computer? Is there any way to tighten up my stock auto until i get something else figured out? I haven't touched my trans and since I went NA-T it isn't very happy with me haha.

 

Well after doing even more reading I see that you can't use the auto with the stock ecu. Guess its time to buy an aem

 

you can probably put a 1jz auto trans in with the stock ecu its mechanical line pressure like the GE, although im not 100% sure how it is on the 97 but most 2jzge non vvti autos are the old mechanical style, and the 2jzgte one is electronically controlled by ecu. maybe someone can confirm or add more info to that im still learning all the auto stuff.
