ANOTHER A6 01E Question. Semi-noob

[darknight01]

Alrighty.

So i sold the 5hp24 from the the A6 (4.2 2001 as a reminder which A6) and a guy is finally piecing together what i need for the 01E swap. I want to go over my checklist of parts and finish with a question. Yes, ive done a lot of searching and a lot of reading from here, motorgeek, audiworld, vwvortex, audiforums, and havent found an answer to just a couple questions. So this is currently everything i have for the swap on the trans. Allroad 01E with everything pictured.





Please correct me if i'm wrong on any of these parts below but i would like to know ALL options that would be bolt on to complete the swap.

- 2.8L 30v AAN Flywheel will bolt up directly to the 4.2 with no modifications and this will allow the stock starter to bolt right up.
- Is there any difference between the A6 2.7 driveshaft and the allroad driveshaft? or will either work?
- Will A6 2.7 01E trans mounts fit or do i need allroad mounts?
- What model clutch/pressure plate can i use? Any 01E clutch and PP?
- Will both the A6 2.7 AND the Allroad CV axles work?
- What rear differentials can i throw in to give it a good gear ratio? not sure if there is a difference a6 2.7? allroad?
- When i get the TCM reflashed what manual file is the best/easiest to use? (not s6 cause i dont want the dead spot in the accel. due to different head)
- I'm assuming i'll need to purchase a pilot bearing?
- I've seen some kits that have an adapter plate to mount trans to motor... is this needed as i've been lead to understand, NO and that the trans will bolt up directly.

I'll be purchasing the parts within the next couple weeks. I just wanna make sure i can cut down as much dead/reorder time as possible.

Well, you've made a grave mistake #1 by getting 01e from an allroad. That's a no-no for A6/S4 to do. Unless you're building A6 for trackign purposes and short gears is something you want. The AR 01e has much shorter gearing which is ridiculously short on allroad (with its bigger wheels), which will be greatly amplified on A6/S4. Allroad spins at 3.3 at 80mph on its wheels, you will be spinning at 3.6k at 80mph, you'll have dreadful fuel economy. 1st and 2nd will be sooo short, the third will feel like a second in stock 6speed A6.

You will also need a differential from Allroad since final drive is 4.35 in this tranny. If you install it as is, it will blow up after 10 miles.

You'll need flanges from S4/A6 with their axles or Allroad axles for Ar tranny.

You can use any 01e mounts from S4/A6, they are all the same.
You can use a6 or allroad driveshaft, should be the same.
Any 01e clutch if you're mating to 01e flywheel. If you use different flywheel, you'll have to get a clutch that works with that flywheel.
TCM will no longer be there, I reckon you're talking about ECU. Somebody else should chime in on this since I don't have first hand eexperience on this.
Pilot bearing... of course, that a part of flywheel package.


But.... you're missing a load of parts. Namely electrical and pedal assembly stuff which is where it gets tricky... Picture tells thousands words although the rear differential/driveshaft will be different since S4 kit is pictured....:

A allroad trans On a 4.2 none the less. God forbid you floored it you'd be on the revlimiter 1-2-3 without even blinking

[Racin2redline]

The a6 and allroad driveshafts are NOT the same, idk what happens when you install an allroad driveshaft on an a6. But I have an a6 driveshaft on my allroad and I had to space the center support down 1 inch with some spacers I made.
Be careful which one you wind up with

Ahh right, the spacer thingies. Forgot about that. Drivetrain in AR is 1" lower than on A6 so it makes sense that driveshaft stays still in line with 1" longer center bearing bracket.

I wouldn't go that route. I (and many others, pop in to quattroworld.com allroad section and ask about it) actually think that in its stock form the allroad 01e in way too short, I can't even imagine it installed in A6... 6th gear being by far ridiculously short.

I went the exact opposite, TDI 01e in allroad (which has the same 1-4 gearing but lower 5th and 6th, with custom 5th and 6th (6th is 0.60:1), my fifth is now longer than stock 6th lol), now we are talking, civilized gears, not the unending shifting around to not rev too high...

[Milehi]

Good, luck on the swap... I'm just finishing up on this as well on my 2001 4.2. My donor car was an '00 2.7 and the parts list from donor car went as follows.
6 speed Transmission
Rear diff
Front axles
Center prop shaft
Transmission mounts
Spacer for trans to engine (the large one, 14mm I think)
Longer bolts to bolt trans to eng
Longer dowels to align trans with eng
Pedal cluster
Shifter/linkage/boot and knob
Flywheel/ pressure plate
Hydraulic clutch line

This is all I can remember right now but I'm sure there was more. I would get the rear differential that the 6 speed was mated with if I were you as the gear ratio has to be the same front and rear... Not sure about the axles /prop shaft and mounts on the all road vs sedan being the same or not.
I had to cut the front (engine side) of the fly wheel down for clearance issues, replaced pressure plate and clutch with new for 2.7. I would recommend replacing the hydraulic line for the master/slave, or having the rubber hose replaced by a reputable hose shop. Put it in FIRST when you start to go back together with it all. You will probably have to make a few slight bends to make the line fit unless you end up replacing the whole pedal cluster, in which case you can get the line in with no problem. If you choose not to unbolt the brake booster it's easiest to get the line in from the bottom. Get new master and slave cylinders as well. I opted to install just the clutch pedal vs replacing the whole pedal cluster. I found that the exhaust hangers on the down pipes don't even come close to where they are supposed to bolt on the tranny mounts. Another slight mod to deal with. Wiring for starter lockout and reverse lights is fairly easy. I'm sure I forgot a few things but It's a fairly easy swap, just time consuming, but will be well worth it when done. Hope some of this helps.

[darknight01]

Now its looking like maybe i should sell the current 01E and get one from the A6/S4 2.7

[rollerton]

You need the matching rear diff- normal 4.2 cars have 3.70 final drive, S6 / A6 /B5 S4 manual 01E trans in USA is 4.11 .

And that trans you have pictured up there looks like an 01E, but ...it has what looks like might a B6/B7 A4 shifter?

[darknight01]

YES. If you get one of those you can leave your existing 4.2 rear diff also.

And that trans you have pictured up there looks like an 01E, but ...it has what looks like might a B6/B7 A4 shifter?

It is an 01E. and the guy said it was from an Allroad. is there anyway i can tell for certain what Gen and what it came out of?

[rollerton]

Look on the bottom/ sides up near the bellhousing for the trans "code" ; it'll be 3 letters like "EDU" . Then read through this thread for more info on stuff about the swap:

http://www.audizine.com/forum/showth...p-parts-thread

Also...not sure about your choice for a flywheel? 2.8L "AAN" flywheel . Never heard of anyone in the U.S. using one on a 4.2. I'm sure there are a few flywheels that would work, but if you want to avoid weird issues you might consider doing what's known to work- either an aftermarket unit (single mass/ lighter) or an OEM 2.7L dual mass.
Maybe the AAN flywheel works? If it does indeed bolt on What I would worry about is if any decent clutch/ pressure plate would work- meaning hold 4.2L power.

AAN is a little 5 cylinder 2.2 engine from earlier audis which is routinely built up to impressive TQ/HP figures, you know 400-500whp as a pretty run of the mill build with pretty much sky being a limit. Clutch choices are aplenty.

ya sorry NOT the AAN. Scott from AdvancedAutomotion said this in another thread
"Depends on the flywheel you use. If you opt for a 30V 2.8 flywheel and clutch or variant you don't need the 2.7 spacer plate and the stock starter works."
I'm assuming the 01A trans is the trans that came in the 30v 2.8???

[gegz]

darknight01 "I'm assuming the 01A trans is the trans that came in the 30v 2.8???" Yes the 01A tranny was in the 30v 2.8 and is a 5 speed. Not sure what clutch kit can go with that flywheel to handle the 4.2L power, maybe an B5 RS4 clutch????

Rollerton are you sure about this??? "YES. If you get one of those you can leave your existing 4.2 rear diff also."

^ I was wrong!^

The S6 has the same final drive (4.11) as the 6 speed A6 (not allroad) and 6 speed B5/S4--but the 4.2 has a 3.70 final drive . My 6 speed S6 still has the old rear diff. Never touched the rear end of car in the swap.
You will need a MANUAL A6 (not allroad) driveshaft. And MANUAL A6 (not Allroad) axles (FWIW I think the left front axle of a B5/S4 works as the right front axle on an A6?).
If you have an Allroad parts car I think about the only useful parts from an Allroad might be some hardware, pedal assembly, and shift linkage/ shifter box- and I guess the hydaulics (master/slave), brackets too I suppose.
But the main parts aren't great for the general purpose of swapping to manual.
If you can't locate a normal-manual A6 propshaft, you can use an auto unit (NOT from allroad or 4.2) and the aluminum spacer Scotty and s4parts.com sells.

[chinaren]

From OP's picture, it is NOT an Allroad 01E, Allroad 01E has different front output flanges, and has oil cooler lines from the driver side. This maybe a normal A6 01E. I am local to you if you need help determine, PM me if you want. Good luck

I attest to this, this one doesn't have cooler lines which are standard on all allroad trannies. OP, check the tranny code.

Alright. I will check monday. its in the trunk of the A6 at school. The bezel though doesnt resemble an A6 though. more like the Allroad trapeszoid. The guy i bought it from said he pulled it from his allroad.

EDIT: actually as i research more. the bezel looks like an S4 bezel.

"Bezel" what are you talking about?

[rollerton]

"Bezel" what are you talking about?

That shifter and trim is from a B6/B7 A4. Could just be something tossed on there for some reason. But, for sure check trans code- don't go shopping for more stuff until you know for sure what you have.

[Widebody4.2]

A allroad trans On a 4.2 none the less. God forbid you floored it you'd be on the revlimiter 1-2-3 without even blinking

So a kid I know has an 4.2 a6 with an allroad box the gears are shorter and it's always screaming but that thing rips out of the hole. It's not as terrible as these guys say but understand its steep.

[Widebody4.2]

Yep. Unless you got a weird 4.2! The 4.2 C5 has the same final drive as the 6 speed A6 (not allroad) and 6 speed B5/S4. My 6 speed S6 still has the old rear diff. Never touched the rear end of car in the swap.
You will need a MANUAL A6 (not allroad) driveshaft. And MANUAL A6 (not Allroad) axles (FWIW I think the left front axle of a B5/S4 works as the right front axle on an A6?).

This isn't true. The s6 has the 4.11's and the slush boxes have something different. We get away with keeping the s6 rear diff because they match the a6/s4 center diff. Look at the pic in the second post there's a rear end and rear axles in it because they don't match unless its a S car.

I went with this option

Car revs way fast and gets chatter from disc.

You better not read about my experiences with fidanza (but that applies to any aluminum FW since they all are made the same):

http://www.audizine.com/forum/showth...comes-apart%29

And I am not the first person this happened to. Cincidentally you'll find in there info on proper single mass FW, the billet steel TTV racing unit which will actually run you only a little more than fidanza ($450ish delivered) while US options from CM/SB for the same thing are $750.

[linust]

Yep. Unless you got a weird 4.2! The 4.2 C5 has the same final drive as the 6 speed A6 (not allroad) and 6 speed B5/S4. My 6 speed S6 still has the old rear diff. Never touched the rear end of car in the swap.

Be careful here...IIRC, amongst the C5 4.2 cars, only the C5 S6 has the 4.11 final drive ratio. The C5 A6 4.2 has a taller (lower number) final drive and requires a rear diff change. The rear differential you want is code EUU, found the C5 S6, C5 A6 2.7t 6sp, and also (I believe) the C5 A6 2.8 tip and one or more D2 A8 (don't know which, and the mounts might be different).

I no longer have Bentley or ETKA installed (upgraded computer) but the data has to be pieced together from a couple different places, and is NOT 100% correct in those sources.

[aysix]

Not sure if it's been mentioned but a new brake fluid from a manual.

Correct, the 4.2 A6 has 2.72??? Final drive so you will need the rear diff to match your 6 speed box.

Corrected- you be speak truf! Scotty says V8 cars are 3.70 final drive.


EUU = 4.11 V6 6mt V8 S models S8
EUT = 3.89 V6 5At
EUS = 3.70 V8 5At
CUB = 4.11 EU 100mm flanges
CUC = 3.89 EU 100mm flanges
ENX = 4.35 Allroad 6mt
ENY = 4.86 Allroad Tip

[darknight01]

Sooo. with the research i've i may have hit the Jackpot. the trans code is AEK. and so i'm pretty sure i have a TDI Trans. :D







Heres a better pic of the shifter and bezel if that helps confirm the model trans

[8520]

That definitely looks like a b6/b7 shifter. Not sure what bearing that has.

[rollerton]

You want to look down on the bottom; like this:

cool. thanks Rollerton. I thought i was looking more for a plate on there like the autos. so when i saw everything on the sides thats what i assumed was needed. I'll check the bottom today.

You were right :)

From OP's picture, it is NOT an Allroad 01E, Allroad 01E has different front output flanges, and has oil cooler lines from the driver side. This maybe a normal A6 01E. I am local to you if you need help determine, PM me if you want. Good luck

Right again about it not being an allroad.

I attest to this, this one doesn't have cooler lines which are standard on all allroad trannies. OP, check the tranny code.

Finally did

You want to look down on the bottom; like this:

So went back and checked on the bottom of the gear box and found the REAL trans code.



So it turns out it is in fact a B6 A4 3.0 01E. Great news is, the final drive is 4.11/1 I noticed the gear ratios are very similar to the allroad but will the 4.11 diff make the difference and give me decent highway mileage. I know others have said with the ALLROAD trans they will be running like 3600RPM going 80 in 6th. Here are the gear ratios for the B6 01E that i have.



So i will most likely be keeping this trans and getting the rest of the kit together.

[rollerton]

I thought that linkage looked kinda short.
Good news / bad news.

Now, I've read the 01e B6 / A4 threads where people wanna swap this and that- your problem is now (as far as I know) that the trans isn't physically compatible with the C5 chassis as-is. You will have to do some research to find the specifics- but as far as I know nobody has installed a B6 trans in a C5. Details start with the B6 using ABS for vehicle speed instead of the sensor on the axle flange a C5 uses. Supposedly the trans mount brackets aren't in the same place either.
I dunno...do some looking ...C5/B5 01E trans into the B6/A4 has been talked about a bunch in the B6 forum.

i Searched and others are chiming in that the 01E is pretty similar across the board on the exterior minus flanges, internals, and a few other small things. So there is bosch sensor on the bell housing. i need to get the part number and find out out what it is.

I will also be checking the measurements of the output flanges on Monday.

FYF would say that it is a B6 trans but it doesnt have B6 output flanges Scotty mentioned. so this trans is just a massive mystery.
