O1E 6 speed

[Peter]

Dumb... won't let me edit my previous post for some reason?? :veryangry:

The pdf link I provided about Audi transmissions in other threads shows the following variations:

5spd Audi 80, 100, 200, A4, A6, A8 is a 012.
6spd Audi 100, 200, A4, A6, A8 is a 01E.
6spd Audi A4, A6, A8 is a 01X.
6spd Audi A4, A6, A8 is a 02A.

Those are the only FWD variations. Rest are AWD or other.

So to me, the 01X or 02A would likely be latest models able to handle more torque, possibly different internals. But what do I know, just a learning newbie. :thumbsup:

Still trying to figure out the model # difference (if any) between gasser and TDI as they apparently have the wider ratios.

-------------------------------------
I suppose you'd have to look up the specific transaxles as listed for sale such as this one:
http://cgi.ebay.de/6-Gang-Schaltgetriebe-f-einen-Audi-A4-B5-A6-4B-A8-D2_W0QQitemZ270267411002QQcmdZViewItemQQptZAutoteile_Zubeh%C3%B6r?hash=item3eed316a3a
to determine what ratios they actually have. In this case they use the identification of DQS. Which is separate from 01E, etc. No idea how that separate ID plays in? This particular one is listed as coming out of an A6 2.5L TDI .... so I suppose you could look up the actual specs of that Audi model to find out the ratios??

Looking at other listings, this time searching for "schaltgetriebe DQS" brings up http://shop.ebay.de/?_from=R40&_trksid=m38&_nkw=schaltgetriebe+DQS where both use 2.5L TDI V6 motors, one is 1998 and other 2002.

So now... looking up the specs: http://www.audi.de/etc/medialib/ngw...6c5.Par.0005.File.pdf/1998_02_a6_c5_25tdi.pdf it lists the ratios as:
1st / 2nd / 3rd / 4th / 5th / 6th
3.5 / 1.889 / 1.231 / 0.871 / 0.667 / 0.561
reverse is 3.455 and axle ratio is 3.875.
Overall ratio top gear 2.17

Interesting stuff. This is a 1998 model year vehicle. Odd thing is, the AWD version of the 6spd manual has a 4.111 ratio R&P and identical gear ratios as the FWD.

Max HP is at 4000rpm. Other odd thing is top speed for FWD is 218km/h and AWD 216km/h.

If you work it out on the FWD then 218 @ 4000 would be 354km/h at 6500rpm or 219mph.... no idea if 4000rpm is what they use for top speed measurement, maybe it's 4500. Who knows?

I should just use the actual ratios themselves and tire size to calculate it but I'm too lazy right now.

-------------------------------------------------
Ok, while we're here, lets check out the 2.8 V6 gasser specs:
http://www.audi.de/etc/medialib/ngw....0007.File.pdf/1998_02_a6_c5_28_28quattro.pdf 1998 model of course.

Scratch that.... show a 5spd with 5th gear as 0.789 and 3.70 R&P ratio. Max hp 6000rpm, max spd 236km/h. Maybe this is the 016 box? Overall ratio 2.92 in top gear vs TDI 6spd of 2.17 overall ratio top gear.

Interesting stuff.
------------------------
Ok, even more stupid data.... LOL

In 2002 the A6 had a 3.0 V6 gasser. Still, only the 5spd available in FWD. Is this a 016? 5th gear is 0.844 final 3.75 for 3.165 overall ratio. But this motor spins higher to 6300. Top speed 243km/h.

Too many numbers.... if we look at A6 2004 model (6spd!) FWD the ratios are:
1st / 2nd / 3rd / 4th / 5th / 6th / Final
3.667 / 2.053 / 1.423 / 1.065 / 0.853 / 0.730 / 3.75
So overall ratio is 2.74 but this one is electronically regulated to 250km/h. 255hp 6500rpm.

Lets go back to the TDI again for 2004 in A6 and FWD 6spd:
1st / 2nd / 3rd / 4th / 5th / 6th / Final
3.665 / 1.999 / 1.407 / 1.00 / 0.742 / 2.984
So overall ratio is 2.21 , which compared to the 1998 2.5L TDI is 2.17 so they are very close.

---------------------------------------------------------
Summary:

Looks like you want a TDI box for higher speed. Overall ratios didn't seem to change much between 1998 and 2004, however, it looks like they used a ton of different gear ratios and R&P's so best to carefully make sure which model year and detailed specs so you know what you are buying.

One small side note, these all had ASR (anti-skid regulation) and EDS (Elektronische Diff. Sperre). So, if you don't drive a newer VAG car ASR stops the wheels spinning and detunes the motor, EDS is your limited slip differential. But from what I can gather it is the car's drivetrain ECU which modulates the front brakes to keep tire spin under control. Basically it's an open diff and a poor man's LS. Saves VAG putting Quaiffe's in there I guess. At least that's my take on it, correct me if I'm wrong.

Some things are right under my nose: http://www.gt40s.com/forum/how-engi...les-audi-016-083-transaxles-pete-tinucci.html good writeup with 01E supplement on the end.

Oh, and I apologize for this long-winded post. If it's too much just tell me to shut up or something. I guess I'm too "GT40" excited and sucking up all and any info I can find.

Not dumb, there are reasons for such forum rules:

"Editing period on your posts does expire - I think it is 1 hour.

As I understand it - It was done like this primarily to discourage people from tossing a verbal grenade into the crowd and then editing so later they could claim innocence..

I find the editing period generally sufficient to correct any spelling / grammatical / content errors."

I think KEP makes an adapter plate (or at least for 016) and another user on here (if you search the "who uses what transaxle in their gt40" thread). Maybe it was Flatchat (a few posts above) or he does'em for the 016. Might be same bolt pattern, I dunno?

Chris, may I ask what was the cost of that 01E you bought from the dealer?

About £3,000 in 2007. Of course as it comes from Germany, it will be priced originally in Euros so if your currency is strong against the Euro (unlike the £) you might get a better deal. There is a version of the 01E that has a take-off for an oil cooler, which I wish I had bought, so I would suggest you do a bit of research into the various versions available before ordering one.

It sounds like the o1e isn't readily available in the U.S.. What kind of HP will the o16 handle.

The 016 is weak, and tend to grenade over 350 hp without modifications. However due to narrower gears, can't handle as much power as the 01E.

Those are the only FWD variations. Rest are AWD or other.

So to me, the 01X or 02A would likely be latest models able to handle more torque, possibly different internals. But what do I know, just a learning newbie. :thumbsup:

The 01X is the weakest of the group, probably as strong as an 016. The 0A2 is a good unit with strength similar to the 01E.

ok, dumb question, why doesn't the porsche 968 box work behind an engine??

 

[Brian Hamilton]

As for clutch selection, I have had lots of experience with SPEC Clutches out of Alabama. They are very knowledgeable and very able to make pretty much any clutch for any application as long as you give them some measurements and a spline count. Those guys are great and I've never had one fail in any Mustang we've ever installed them in. Including a 711 hp turbocharged monster.

 

[Peter]

I take it from all the reading I've done on here (build logs, etc) that everyone is using the OE hydraulic clutch release setup?

Well... it's good news these are readily available (in Europe). Convenient as my buddy is a VW/Audi specialist if I need to rebuild one of these boxes in the future.

The 968 doesn't work easily behind a v8 because it has no provision for a slave cylinder and it has no machined tip on the input shaft for the pilot bearing. But these could be easily rectified.

Only 1st gear in the 01E is wider than the 016 gears. All the others 2-6 are the same width as the 016. What is different is that the driven 3rd and 4th gears are splined instead of just press fit as on the 016. (the 944 turbo, 944S and 944S2 also have splined 3rd and 4th)
