Any info on the 4-speed automatic in the UrS6/other models please...
 

Looking into a UrS6 w/4-speed automatic and inline five (European). How much torque can this automatic handle? Is it the same as the unit in the 4.2V8 UrS6 (and UrS6 Plus)?

Anyone driven this autobox? Shiftpoints? Does it have DSP or a sport setting - does it need one?

Since this 4-speed wasn't available int he UrS6 in the US, what about other models of that age (96) with a 4-speed ?

Thanks,

Laurens

I have two of them with the 4-speed... '94 100CS and '96 A6 Quattro. 100CS runs fine, shifts smoothly, etc... but the A6 with Quattro shifts with hesitation, holds 3rd gear at times, and shifts into 2nd and 3rd gear with a 'chirp'. I have it going in for service on Tuesday to see how bad it is. I have always doubted the 4-speed and have heard of many owners who have had their entire transmission replaced after having symptoms similar to mine.

In terms of intended performance, the transmission seems to adjust to your driving style. But even so, it shifts into 2nd gear at 3-10 mph in normal driving, and will only make it to a respectable 20-25mph in 1st if you accelerate rather heavily, which usually isn't needed on the streets.

I'd say you'd be on your own if you added anything in terms of hp to 20v already at 258ft-lbs of torque… and a 4.2 w/4-speed being at 290hp on the S6 4.2, torque is probably at 300ft-lbs++. I just doubt the 4-speed could handle that much torque without failing. I’d doubt it at 258ft-lbs in the 20v UrS6. Plus performance is hurt by the 4-speed... you'll lose over a second on 0-100km acceleration.

If I had the choice I'd go with the 5-speed (or 6-speed on 4.2 or S6 Plus). Just IMO, I don't think the transmission is built well enough to hold up to high(er) torque loads.

Good luck...<p>>>Muhammad

I will drive some 4.2UrS6's at some stage...
 

A nearby German dealer has at least 2 or 3 black
UrS6 avants. All with the 4-speed automatic. I
(yet) don't know their milage.

They're the 4.2l versions which I'm not after,
the 2.2l should be enough and saves fuel, and I
like the sedan better, but they're rare in Europe.

Thanks for your reply!

Do you feel the weakness it's quattro related?

Could be...
 

Since that's the only difference between the cars. Quattro adds a bunch of weight, and worsens performance, handling, etc... also ride quality is softer (matter of taste/use). SLIGHTLY better dry surface traction, but I can't notice much difference in the rain, and have yet to take the Quattro in snow... FWD did fine in snow the past two years with only all-season tires mounted.

I am no automotive technician so I don't know exactly what type of additional strain Quattro puts in the transmission, but I would say it must count for something from the driving feel of both cars.<p>>>Muhammad

The US 4.2 tip is a 5 speed guys...not a 4 speed.

He's talking about an UrS6 4.2, not an A6 4.2 (more)
 

The C4 bodied S6 4.2 apparently came w/ a 4-speed automatic. The 5-speed tiptronic box was not even in existence when this car debuted, nor was it ever offered in the UrS6.

I would not buy one of these cars, personally, but that is due to my manual transmission bias.

The same box is in the V8 and the A8 (basically- the early A8s w/ the 4-speed), so I don't see a problem w/ the torque capacity unless you plan on doing something that would radically increase the torque output (twin turbos, supercharger or the like).

Are you positive?
 

It the same transmission in all of these cars,
or are they all alike as in that they're 4-speed?

As a comparison: a 1.8T tip is different from a
S6 4.2 tip although they're all 5-speed.

Thanks!

You couldn't know but the 2.2liter is an inline-5 and wasn't available in the US

Uhm.. my bad... the 4.2 V8 wasn't... it's Friday you know ;)
