Here's some transmission information I've gleaned off the web
concerning Volkswagen transaxles. There are two important numbers/codes
to use to identify a Volkswagen transaxle. First is the Volkswagen part
number. Amazingly, the "020" transaxle will have a Volkswagen
p/n that starts with "020", for example the "FF"

transaxle, circled in light blue in the above
left image. It is a 2 or 3 letter transaxle designation consists of the
first 2 or 3 letters of the transaxle code. For example, my 020

in the transaxle, the actual gear needed will depend upon the final
drive ratio of the transaxle.
