Introduction:

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 is p/n "020-300-044-X" and the FN is "020-300-044-NX".

The other code number to find is stamped into the bottom of the 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 transaxle is:

FN03033

This signifies its an "FN" transaxle, and a mfg. date of 03/03/(8)3 or Mar. 3, 1983, in the format of DDMMY (with the 10's digit of the year assumed to be 8 - as in 80).

In the above right image, you'll see a top view of the transaxle.

One minor difference that you might run into with the various 020 transaxle versions is what chassis that transaxle was originally installed in:

Note: If you find an mistakes, omissions or have more information to add, please let me know.

Speedometer Drive Gears:

There are 3 available speedometer drive gears available for the 020 transaxle. Since the speedo gear is driven off of an intermediate shaft in the transaxle, the actual gear needed will depend upon the final drive ratio of the transaxle.
