The 01e and other 6 speed audi transaxle info you have all been waiting for

[Jack]

Hi all, I've been lurking here for a while and thought it was time to add to the discussion.

I am based in the UK and have been installing 01e transaxles into porsche 944s and have come to learn a lot about different codes, shifter setups, axles, cv joints etc. I wouldnt say im a total expert but im close to it i guess. I often find myself directed to your forum from online searching and it seems our needs are shared even though the porsche has a torque tube. I see threads here that don't get concluded with questions about the audi transaxles so just wanted to say I'm here to answer anything you want to throw at me. My knowledge is mainly around 01e variants but I do have knowledge of the 0a2, 01x, g87 transaxles that are similar in form factor as I have explored fitting these to the 944 also.

In addition. I can also supply FWD 01e transaxles to the USA if needed and I can even supply complete cable shifter setups customised to the gt40, axles, cv adapters, an entire kit for the transaxle installation etc if there is interest. It would be based upon my 944 offering which I have attached some images of but let's see if anyone wants it before I shove that down your throat.

Cheers,
Jack

Hello! I’m interested I have a O1E mated to a ford modular engine and can’t find any ready made ways to set up the shifter at the gear box end. I have a cable shifter (I was originally going to use a Porsche G50 gearbox) so if I could reuse that it would be great..

Hi Jack. I'm building a car with a Audi 500E AAZ 016 transaxle in a rear engine configuration. I would be interested in the price for the very nice looking gearlever mechanism only, I have cables and mounting brackets. Also do you have a neat solution for the transaxle end. I have mocked up the ball and lever style attachment on the gearshift input. Can Email me at fballinger@oddy.co.za if you prefer

Thanks for the responses. My shifter setup is pretty unique in the leverage ratios it uses due to packaging constraints i designed around in the original application. i dont think you will find that its compatible with any other shifter options. there are so many parameters to make the shifter compatible that the chances are just too low for 100% function and feel as intended.

I can of course offer individual parts if you want to take the gamble but i believe you will find yourself disappointed. maybe if you created your own shifter housing (the black box that the shifter is mounted to in my image) then you could open up a bit more freedom.

an example of ways it might not work with other systems - there is a window of lever throw which the shifter can operate. if you try to make it work outside that with a longer throw at the other end of the cable, it will bind up at the lever before it makes the shift on the transaxle for example.

If you want to get an idea of what is happening at the rear and the lengths of those linkages, i have a rather long and detailed installation video on youtube which covers every part:

No worries, what would be the cost for the entire setup then? Thanks!

Hello jack, do you have any solution for gearshifter on my Replica rear/middle engine car, i use Audi 016

[Fred W Ballinger]

Hi Jack, I have a shift housing , I am asking about just the silver mechanism at the bottom of the gearlever. I agree that the cable travel is the key issue. Just tell us how many mm of cable travel your mechanism gives for the longitudinal and transverse directions of gearlever movement and we can go from there.

 

[Jack]

For a complete shifter setup with all linkages and everything you need including custom length cables it would be something like £2000

01e only at the moment im afraid but the 016 may be supported in the future. i cant give a timeline on that though right now so dont wait around for me

The cables i use are 2" of travel and it basically uses all of that if you set it to the longest throw setting. I hope that answers your question?

Hey Jack, I have an 01e connected to a BMW v12 for a Diablo mid-engine build. Will your set up work? Thanks

Yes it will work if it's an 01e. I can do custom cable lengths to suit your car also...

Hello Jack with best regards from Germany. I have a CAV replica with an aluminium block and heads 427 cuinch Ford and the conventional Quaife tranny. It broke on a hard launch when shifting from 1st to 2nd, the rear cover cracked all around and since they are known to be constructed for 500 HP max, I thought that a 01E could be a solution. I found a A6 B4 2.7t DPV 6 spd and wonder, if you can offer what I need to replace my Quaife transaxle and if you think the 01E is strong enough.
Thanks and I’m glad for any advice

I believe that a6 will be Quattro with that engine? the 4wd 01e is a different architecture to the 2wd one and i would advise looking for a 2wd one. I don't really want to make recommendations for the strength of the 01e as i haven't personally found its limits but this is very well documented online elsewhere and you should have plenty of information to make your own conclusions.

DQS is the gearbox code you want in relation to best ratio.

DQS is the gearbox code you want in relation to best ratio.

Best is a very subjective answer and depends a lot on the engine used. In an attempt not to proliferate false information i will share the main 01e ratios below appended on a table of common porsche 944 gearbox ratios which you will have to ignore.

I will also add that although the DQS is often quoted as the strongest variant, there are newer versions of the 01e and they have visually more meat on the output flanges which suggests they may have improvements over the older DQS. the ratios of these are slightly different and i would only be speculating if i tried to suggest why Audi or Getrag decided it was worth making a new revision.

 

[Scott]

People that state one 01E variant over the other is "stronger" often have nothing to base their claims on. All 01E's are of similar "strength" made after 1996, with the exception of one variant used in early 2000 in the A8, it has a larger differential, which would make that part "stronger". Don't bother looking for one though they are extremely rare only used for about 6 months in late 99 and early 2000. When you find them sellers often think they are made of gold or platinum. Except for the previous mentioned example, after 1996 all front wheel drive 01Es are of similar "strength" internally. There are output flange differences but those are due to using different CV joints, and you will likely blow up a differential before those fail.
Propr to 1996 01Es has a first gear with a narrower width, which could be damaged more easily by poor driving habits or too much power.

I will also add that although the DQS is often quoted as the strongest variant,

Hi Scott, great to see you here on this board.

I like to give everyone the information that helps them make their own decision and so i feel the need to share the following which does not agree with your statement about them all being of equal strength. The short ratio variants even from the latest production years have the "narrow" 22mm wide 1st gear compared to the wider 1st from the variants that came behind a TDI motor.

I will also elaborate on my comment about the output flanges. the later TDI output flanges are the same diameter and PCD as the DQS but they are thicker. i completely agree with you about this not being a point of concern as its not the weakest link in the chain but it does make one wonder what else they changed inside and why they would have beefed up the output flanges on later variants. could you shed any light on this as you have probably opened up way more of them than i have? i am referring to those with the FRK or ELN code vs the DQS

Post in thread 'which audi 6 speed diesel box for my 302?'

Dec 27, 2024

Found this on another forum. The 0A2 has a very tall 6th gear, which is ideal for larger displacement engines (V8 conversions, etc.).

The 0A2 and the G87.21 have the same mounting flange bolt pattern. The G86.20 has a different mounting pattern.

Did all of these exist cable operated?

• CTCH

• 

There are some tall ratio gearboxes, apparently for the Diesel engines.

I was wondering if we had more information on the following gearboxes:
0A2 (same mounting flange as the 0A1)
G87.21 (same mounting flange as the 0A1)
G86.20 (different mounting flange)

All of these should have the same internals as the Getrag G466 but different ratios available. Can all of these be cable operated?

Which 0A2 gearbox codes are there?

Which 0A2 gearbox codes are there?

I made that original post on a porche forum. It was long before I completed the conversion and was selling spline adapters only at that stage. I should really delete the post as I no longer believe the 0a2 is the best choice and I have now fixed the supply issues for the 01e by sourcing them for people myself at a very reasonable rate.

I would also like to ask that you edit your question so that you do not mislead anyone in future. I believe you mean to compare to the 01a when you typed 0a1. The 0a2 will bolt to the 4 cylinder vw/audi engines just like the 01a will but I don't know that all the hole are exactly the same.

I cant help with the g86. I know very little about it.

The g87 is the 6 speed from the 987. I know that there are 2 variants which are the g87.20 and g87.21. I also know that one of those variants has the audi bellhousing as its the 6 speed dealer option for the 2.7 litre engine. The other variant comes on the larger 987S engine. I do not know which is which at this stage.

The g466 is not a number I recognise but the internals of the 01a and 0a2 are certainly not the same. There are lots of 0a2 parts inside a g87 but I can't say what percentage. The g86 is definitely different also.

 

[Alexander M]

Thanks for the swift reply. Can you outline your conclusions on why you think the 0A2 is no longer a good alternative to the 01E?

I have posted the 0A2 gearbox codes for 2WD here:

Thread 'Audi 2.7TDI transaxle'

Sep 1, 2010

Hi everyone

I'm looking for info about the Audi A6 2.7TDI front wheel drive transaxle box. (180-190HP-380Nm, 2005-2010)

I have looked and searched on this forum for info about the box but I haven’t found so much about this particular box, but pretty plenty of the 016 and the 01E boxes.
How good does this stand up against the 01E or the 016?
Any negative/positive info?

Thanks

GETRAG is the company that made the 996 gearboxes.

Getrag - Wikipedia

They turned that into the G86.20. Then seemed to have discontinued that gearbox later and changed over to 0A2 which was the Audi successor of the 01E and made in much larger numbers, hence likely less expensive for Porsche so they just used that going further?
