May try shoving a 6HP26A into the car...

[JSRS6]

For the v10 s6:

A ZF 6HP26 six-speed tiptronic automatic transmission (parts code: 09E, identification codes: JBW, JMS, KHD, JLL) (gear ratios - 1st: 4.171, 2nd: 2.340, 3rd: 1.521, 4th: 1.143, 5th: 0.867, 6th: 0.691), with steering wheel-mounted "paddle-shifters" is the only transmission available. Torsen-based quattro permanent four-wheel drive - initially with the T-2 symmetrical differential, and from 2007 model year with the latest 40:60 front:rear asymmetric/dynamic Torsen T-3 differential, is standard. The final drive ratio is 3.801. Traction is assisted "Electronic Differential Lock" (EDL) and "Anti-Slip Regulation" (ASR) (commonly known as traction control system) - both functions of the Bosch ESP 8.0 Electronic Stability Programme.

It looks like the running gear ratios are the same for all the 6hp26 trans.

This is odd, it shows a 2004-2006 phaeton with 4.2 having a 6hp19... Hmmm

The axle line is ~7" from the motor on yours. the 6HP26 is around 2". You need to put a 5" spacer to have the axles straight. You also need to extend your TC by 5". Only the 6HP19 would fit without major fabrication.

[nitrorocket]

The big question is, do I have to change the rear differential or not?

[nitrorocket]

No ABS would be a blessing! Lol

[Bigglezworth]

Good price...

There is NO way that unit is bolting up to the C5 RS6 engine. The centerline of the front diff on this one is clearly further forward and almost past the mounting flange to the engine. The 5hp24 is significantly further back. This excercise is about more than just adapting a bellhousing, gearing, and TCU. Itabout physical alignmenet of the front drive axles within the chassis AND, ensuring sufficient space within the transmission tunnel to locate the two turbos. Massive bellhousing that has the TC located further towards the rear is even larger than the C5 and robs the necessary space for turbos and downpipes. WAY too much Frankensteining for even the most seasoned backyard autohead.

But doesn't the six speed manual fit into our cars? I'm pretty sure I saw that has been done. So that would mean the six speed manual and the six speed automatic should have the same centerlines. No?

The 5/6 speed 01E fits but not naturally.

The block from the RS6 and the D2 A8 are exactly the same, but I'm pretty sure the upper oil pan/skirt is different since the D3 doesn't need turbo oil return lines. Therefore, I'm not sure if the bolt pattern between them is exact below say 4 to 8 o'clock.

Pictured here is a spacer from a W12 Phaeton overlayed on the RS6 block. I'd be happy with this bolt/attachment coverage even though there's not an easy way to get a bolt at 10 o'clock.


It looks like there is conflicting information on what the transmission looks like or if there are different variations? The eBay one seems to be verified from a D3 A8 and confirms what I've heard, which is that the front diff is farther forward and would throw off the geometry of the front axles and interfere with the passenger side exhaust manifold among other things. Although, it looks like there's a spacer that is needed. See the pics of the engine that the eBay transmission came from (http://www.ebay.com/itm/2005-AUDI-A8...item19e8853256). Maybe it will bolt and actually work from a mechanical standpoint???

Electronic standpoint. I have no idea. If my S6/RS6 project was finished, I'd consider buying a D3 and sell you the transmission and all the guts and try to put an 01E in it.

[nitrorocket]

Does the RS4, with a manual and automatic transmission?

[nitrorocket]

Here is one out of a phaeton.

[nitrorocket]

So it appears that the RS4 and the phaeton might have the same transmission, and the a8 is different.

[JSRS6]

I think you are on to something. Phaeton/rs4 trans looks more like 5hp in ours.

[TozoM8]

That will be nearly impossible. Aside of the physical dimension differences, the 6HP26 has the TCU inside the trans.

I'm glad you chimed in on this, as I remember talking to you about this a couple years ago.

Do you know what kind of transmission is pictured strapped to the jack?

Also do you have any leads on any S8s with bad transmissions?

The trans on the jack is a 6HP19 out of a 4.2 Phaeton. The D3 A8 also has the 6HP19.
Unfortunatelly the D2 got old so people junking them.
The 6HP26 is way stronger than the 5HP24. The Aston Martin DB9 has it and it holds up with that V12 with no problems.

[mik15]

plus you would need 6hp32, the 26 wouldn't be able to cope with the high torque, it's only rated for 550NM i believe, while the 6hp32 is 750NM rated...or even better the 6hp34 to make sure you get a higher range of torque limit.

[nitrorocket]

Tozo, it still apears to be comtrolled by a tcu in the phaeton. Here is a pic, looks just like the rs6 tcu... Maybe there is a secondary controller inside the transmission, but it still appears to be controlled by the TCU and as long as you get the harness going between the transmission and the TCU, it should function. Pretty sure I'm gonna find out.

Soooo, everyone says the 6hp26 is stronger than the 5hp. And im guessing if it will hold behind the 2008-2010 RS6, it will be fine in hours.

If anybody can help me lineup a wiring schematic for the phaeton and the RS6, ill tell you if it will work. I do a lot of custom rewiring of different cars, im hoping to figure this one out too. Theoretically I can always just use a standalone control module with inputs from the engine.
