I've been trying to find documentation showing what model transmissions came in what year / model cars. I thought I had come across one at some time but cannot find it again for the life of me.

A520

A525

A523

A543

A555

A568

I'm trying to wrap my head around which is what, what internals can interchange, which had the reverse in top left vs bottom right etc etc.

Thanks for any links / help.
