Since there is still a lot of stuff about these not known exactly and many confusing topics, thousand of pages and myths, I will try here to make it easier. If anyone has additional information or something is not right, please post, then I will modify the 1 post.
This is for stock factory transmissions only, NOT competition ones.
There are A, B and C types transmissions ( C was never used in Z cars so I will not add these here )
Update 9/7-21 : Also the 4.11 ratio R180 was not used on Z cars ( correct me if I am wrong )
Also not sure if 3.90 was used in the USA on the 260/280Z and ZX
So far I have:
