Six Speed quattro transmission from and Audi S4 are not going to be a good choice for your car. They're rated for AWD torque, and if converted over to FWD they'll grenade quick.. alot of the Ultima guys have tried this and get nowhere quick. You may look for an 01X FWD transaxle which already has the center diff removed. 01A and 01E designations are the quattro 5 and 6 speeds respectfully.
Biggest issue with the audi transmission is the long one piece input shaft with integral 1st/3rd gears. They just can't take the torque load not being distributed across the entire case as in AWD. you can get one off input shaft made with separate gearsets for 1st/3rd but they cost a boot load and would put you into used G50 territory easy by the time you get done with the parts and overhaul.........
If you're not going to put a G50 in that beutiful car, you'd be better off doing this with a JDM 6MT from a subaru STi than with the Audi counterparts......with durability and strength in mind. but then again that's a $3-5K transmission in itself when found and is just as expensive as a used G50

According to this guy the 01X is the 2wd box and the 01E and 01A are quatro 6 and 5 speed boxes. During my search all of the adds for the AUDI Bentley repair manual lists these the same way.
from one add:
Transmissions covered:
- 5-Spd. Manual Transmission 012/01W Front Wheel Drive
- 5-Spd. Manual Transmission 01A All Wheel Drive (quattro)
- 6-Spd. Manual Transmission 01E All Wheel Drive (quattro)
- 6-Spd. Manual Transmission 01X Front Wheel Drive
- 6-Spd. Manual Transmission 02X All Wheel Drive
- 6-Spd. Manual Transmission 0A3 All Wheel Drive
- 5-Spd. Automatic Transmission 01V All Wheel Drive (quattro)
- 6-Spd. Automatic Transmission 09L All Wheel Drive (quattro)
- Continuously Variable Transmission (CVT) 01J Front Wheel Drive
- Rear Final Drive
- Rear Final Drive 0AR
So maybe these are basically the same?
