the code are STAMPED undreneath the diffhousing....like the AEU OR AEC letter
the part are not stronger than the others.the 4,111 ratio stands in the v8 (89-93)ones also.

I know Jeffers is using an EDU box on his car and thats around the 500bhp mark and that takes hard launches as well, so would be worth looking for, altho they arent cheap.

I plan on fitting mine soon!

How can you fit it when you aint got a car?

@ S2driver UK, Dialynx do not use the UR Quattro box, they use a Sport box and I know.

The later S2 gear boxes are teh same as an RS2 box. The RS2 box is VERY strong. Why would one need to upgrade?

Just wasn't sure about what sort of torque these boxes can handle.

Are you sure the later boxes are the same as RS2?

Not sure what box code mine is. I have an ABY 1995 - anyone know what box I might have?

I do like a hefty first gear launch!! :mischeif:

According the family album 1995 ABY wont have the RS2 box. (i have a 95 ABY and can confirm this) infact non of them on the album have the RS2 box.

ABY box is CGR and RS2 is CRB

Some late 96 S2's may by chance have the CRB box i think Doug_RS2 car had the box.

[YumyJager]

The late CGR as the same main shaft and first gear as the CRB. Look closely at the link I provided ;-)

[martinjs]

Yes the late ABY CGR's with ID numbers 77644 onwards are pretty much the same as the CRB, i have one in my garage
@quattrofever,the code and build number are stamped into the bottom of the housing.

Visible from underneath the car?

[martinjs]

Yes, in the region between the driveshafts, pretty much the lowest part of the casing.
Usually covered in c**p so give it a clean if you cant see it.

This site contains lots of useful info, http://www.elektro.com/~audi/01E/
Boxes with the wider gear have a 'bulge' in the housing to accomodate it.

Geez i've got to get my hands dirty under my car Boo!

Looks promising though http://www.elektro.com/~audi/01E/ind1.html

Q. What's this talk about the wider first gear?
A. There is a problem with the early 01E series of transmissions. First gear is not wide enough for the loads that a turbo can produce under some situations. This has happened in both chipped and non-chipped cars. Audi made the RS2 transmission with a wider first gear to handle the increased torque. This change then made it into the S2 in late 1994 and finally into the S6 in June of 1995. If your S6 was a June '95 build date or later, you should check your transmission serial number to see if it is "CBD 79445" or above. If so, you have the wider first gear. One lister has destroyed first gear in three transmissions. He says he has a list of other s-listers who have the same problem. The author of this web page, Charlie Smith, personally experienced the problem. There is a description of the symptoms of the problem just below in this web page.

reassuring to know how strong my gearbox is on the UR Q...
Will there be issues mating the ABY engine to the 016 gearbox???

ps. sorry for hiijack
