Audi 2.7 Tdi Fwd 6 Speed

[EGLITOM]

Hallo all

would need your help.

Tried the search but could not find sufficiant answer on my question although i´m sure it´s out there.

I would be interested to know if anyone has tried or knows if a transmission of an AUDI A4/A6 2,7 TDI ront whell drive will fit in a GT 40 with a SBF.

I found the ratios on the net which are:
1st: 3,556
2nd: 1,905
3rd: 1,241
4th: 0,882
5th: 0,659
6th, 0,558
Final drive: 3,875

I have heara that some CAV owners used it.

What would be the exact type to look for

It also has an electronic activated LSD ( ESD) . Could this be used somehow.
I also assume that it is strong enough to support an 331 with app 450 HP, because the TD guys in germany run their chipped TDI´s with more than 450 NM of torque through this and the car is much heavier.

Any help aprriciated
Thanks
TOM

well isn´t it a 2.5tdi v6 you mean?
there is a 2.7litre v6 too but thats a petrol engine. and with turbos found in s4..

if so that´s what iam going to use too!
if you search for 01e you will find god stuff here...
model 01E type ARX
i´ts been around from the mid 90:s
there are several variants of this gearbox.
iron or aluminium gearhousing
thin or wide 1st gear

if i´m not misstaken the best type would bee a ARX gearbox with iron housing and wide first gear.

Hi Tom,
I am running an AUdi diesel box, or will be. It is an 01X. The same box is being run in another forum member's Lotus Esprit V8 conversion with an Audi 4.2 and as far as I know it is holding up well at the moment.

@tobias
it is the A4 2,7 TDI ( i think sold as of 2005) 180 HP FWD 380 NM . I drive this one a my company car.
But if i understand you correct it would be one 01e type gearbox.

@ Brett
any detailed code on yours ?

I will try the search function again, but up to know i did´nt find any detailed description of 01e codes, ratios and car types in which they could be found.

Thanks for even more help

Tom,
I don't think mine is a 2.7, but the code is FYA. The ratios that I have been told work out pretty good. The people eho stripped mine down said it was as substantial if not a bit more than the 016 that people have used in other 40s.

Hallo
Thanks for the input.
Find onby the "famous" Gearspeedtable already provided on this forum.
I modified it even a little more (one can enter the tiredimensions, and have a rough diametercalculation of it which is than integrated in the speed chart, you will be surprised how much influence tyres have on the total gearing)
I did it with the hoosier tyres which for example are used by Ron Mc Call,( i adapted the traditional dimensioning of them to the new one, so that i will com out wiht the diameter Hoosier is showing on their site).
I did the table with different gearboxes ( 2 G50 and 2 Audi). For me the G50/04 (swiss version) has the most usable gearing, a low first and then nice close 2nd to 5th. Also i terms of highspeed it looks reasonable to bring all the power down ( at least with a high turning 331 mill, which i assumed). THe Audi 2,7 TDI bx just doesn´t fit, one yould just use 4 gears of it , may be the 6th as a long overdrive.

What do you think about extending this table?
Just copy one table and insert it with the name of your gearbox. enter your ratios and tiresize. If we keep going we would have a nice overview of all the possible combinations. Would be interested in your feedback

Hi all,

New to the formum (great place) and pondering on building a mid engined prototype car from scratch (v6 approx 250bhp) I've seen an Audi 5sp, fwd gearbox from a 1995 A6 2.5 tdi, engine code AAT for sale and was wondering if this would be a 01x or other. I've searched the interweb for a few hours but can't find any info connecting engine codes to gearboxes.

TIA

Mark

Mark, Here is somthing i posted a couple of years ago it does not show your AAT code but it may help, it is in german, but it's fairly simple to work out what it means.

on vag cat i have only found 3.0 tdi. but vag cat may bee wrong. that motor should have a 01x. if it is equipped with manual fwd at all.

Mark
a 1995 a6 2.5tdi should bee a 01e, but thats a 6sp. I don´t think there is a 5sp 01e but what do i know.. if you have a 5sp it might bee an 012 wich is a weaker gearbox than the 016 01e and 01x...

Thanks for the help. Here is a picture of the box.

Here is pic of the 01X outside

and the bits that matter

[Brett James-McCall]

According to the powers that be it was used on a 2003 A4 TDi and had these ratios

Final drive

32 : 9 = 3.556

1st gear

33 : 9 = 3.667

2nd gear

39 : 19 = 2.053

3rd gear

37 : 27 = 1.370

4th gear

32 : 31 = 1.032

5th gear

28 : 35 = 0.800

6th gear

25 : 38 = 0.658

Reverse gear

34 : 10 = 3.400

@ BRett

i put your ratios into the excel table. Just change the tire size to your personal choice and look at your speeds.

It is not bad, althoug in my opinion :
1st is to short ( means speed to low)
5 th is almost to long ( means speed to high)
6 th is a pure overdrive

Thanks

Thanks for all the help and info guys.

I gave the gearbox I was looking at a miss.

There are a couple of 01e (can now id with aid of pdf ) on e-bay but are £500. Is this a reasonable price in the UK?

Is there a similar list for 016 types?

BTW I noticed that the 01x is used with the highest BHP engines on that list. Is the 01x generally known for this.

On another note I tried using the search function to find out more about the Audi transaxle but get 0 results when using 01e, 01x etc and if I try Audi transaxle or similar I get all the results for Audi without transaxle. Is there a phrase search available?

Thanks again.

Thanks Tom,
Yes I was aware of that. I thin it is sometimes hard to find a great gearing ratio from a production box. There will always be compromises IMO. I also find there appears to be a trend, well for the company I work for anyway, to have increasingly shorter first gears.

Mark,
If you can get an 01E for £500 then I personally would go for it depending on condition etc. They sell new for over £1200 generally. I have found it hard to find information out as well. It took me a long time just to get someone to get me the gear ratios! The box is quite new and so it sometimes can take a while for the info to filter out from VAG I guess.

One other thing to be aware of. The 01E and 01X run 104mm PCD output flanges, as Audi changed them from the old 112mm on the 016. These are not common and can't be bought from parts sellers yet. There are a few that are starting to come on fleabay now, but otherwise you will have to make adaptors like Andy Hills did for his Lotus Esprit V8 conversion. If you want to know what I also had to go through to mate mine up to the SBF, PM me.
