Are all Audi 6 speeds 01E's?

This is a great site you guys have here, great information and a great group of people. Question for today is are all Audi 6 speeds 01E's? I have been on ebay.de and have managed to find several Audi 6 speeds that are 2WD but I want to make sure they are 01E and not something else...hopefully I am moving in the foward direction here!

vairking,

cheers

Any easy ways to determine if an Audi 6 speed is an 01E or not?

I have an 01X and it is an 6 speed
