Tranny gear ratios:
Never could get Goober to correct AW site. Mistakes in both Bentley & ETKA
225Q 6-speed
1st 41:12 = 3.417
2nd 40:19 = 2.105
3rd 40:28 = 1.429
4th 37:34 = 1.088
5th 34:31 = 1.097
6th 31:34 = 0.912
rev 30:12 x 23:14 = 4.107
final drive 1st-4th 63:15 = 4.200
final drive 5th,6th & rev 63:19 = 3.316
bevel boxes - 17:27 x 27:17
180Q 5-speed
1st 42:11 = 3.818
2nd 40:19 = 2.105
3rd 39:29 = 1.345
4th 35:36 = 0.972
5th 32:33 = 0.970
rev 31:11 x 23:14 = 4.630
final drive 1st-4th 63:15 = 4.200
final drive 5th & rev 63:19 = 3.316
bevel boxes - 17:27 x 27:17
180 FWD 5-speed
1st 33:10 = 3.300
2nd 35:18 = 1.944
3rd 34:26 = 1.308
4th 30:29 = 1.034
5th 31:37 = 0.838
rev 17:10 x 36:20 = 3.060
final drive 63:16 = 3.938
As was stated, to keep tranny compact on Quattro models two shafts are in contact with the ring gear; one for gears 1-4 the other for gears 5,rev & if present 6th. Pinion teeth count is different, 15 & 19; Goober can't comprehend this. Remember, all modern transmissions are constant mesh design (mating gears are always in contact with each other, torque path is determined by locking connection to spline).

Since the 5 and 6 speed boxes for the Quattros have the same design - could you just add a 6th gear
to a 5 speed quattro gear box? I figure it may be pretty simple considering they share the same internal design.

I doubt it, but even if you could... it would be kinda of pointless. I mean all it would give you is a even lower cruising RPM/ better gas mileage on the highway. I would not give you the acceleration advantages of swapping all 6 gears out.

Yes, spacer sleeve in 5-speed ; however...
You need all new gears except 2nd & 5th (now 6th) for your box.
