Its been told - that you can use the speedo gear as a "dipstick measure".Half way up the gear mesh is supposed to be "A=OK".I made one of the DIY tool bits to fit the plugs - from a bolt and 2 nuts locked together. Heating / hammer tapping / good tool bit should get it loose.But speedo hole works too, of course.Good Luck

I welded a cut down wheel bolt with the 17mm head into a socket. I hated the bolt wobbling in the socket, so that eliminated that.Also, IIRC according to BROKE VW, you can check the site. For AAZ years of 020 it should just be fill to the level. The later year trans had a slightly higher fill hole so you didn't need to top it off at through the speedo hole. He has an identifying pic on his site somewhere.
got it figured, never got the bolt out, but put 2 quarts in, and was able to poke my finger down and feel the level by the plug. worked great
