Since you've done a manual conversion already, I've got a few questions for you, if you dont mind answering.
Can we use just any 01E transmission? Are they all the same from the inside out?
Most of the conversions I saw were done using 01E on 2.7T, and if I remember correctly S6 came with a manual version in Europe as well.
Would that be a better transmission to use? Or that IS the 01E tranny on the S6? What about the 0A3 transmission used on b6/7 S4s?
Thanks in advance, Cheers
The 01E external dimensions are similar, there are a few subtle differences throughout the years however. Early cases (pre 1998) have the bolt pattern on the bell housing differing by two bolts and a dowel pin. The later transmissions also have provisions for the heat shields installed over the front axles, versus below for the earlier transmissions.

The gear ratios also differ as well, there are 3 choices for final drive and several other choices for 1-6 ratios.

I've put together a swap kit using a rebuilt tdi transmission for ~$3500.00 shipped for a few other list members. If you go the used route keep in mind that the 01E's are pretty problematic in regards to the 1-2 collar and fixing that costs ~$1100 plus labor.

The 0A3 is a different transmission entirely.. As Siena stated. The trans mounts differ, the shifter differ, there is only one style of output flange on the axles, the bolt pattern differ slightly and there are no provisions for a speedmeter pickup on the 0A3.
