Hi, welcome to the forum.
VW semi-auto gearbox codes start with 'B' so it won't be one of those and they are all IRS with a CV joint at both ends of each half-shaft. Beetles never got a fully automatic box so if it's fully auto it could be a type4 box from a varient, but not sure on the EA code either, sorry.
If it is auto or semi auto then you're stuck with that, no way to change it.
You can pick up second hand gearboxes fairly cheeply if you need another one?
Could you post any pictures of your gearbox and engine and I'll try and work out what they're from...
:roll:
