Next car will be a 1.8t, like the motor too much, but I don't like the drive train, so 6speed is a must, and back in S4 brakes go off my car.

That or ill find an S4 with a bad motor and swap in the 1.8t.

Who here has done the swap.

I know what it takes to do, I am just wondering if there is anyone at all with a 6 speed 1.8t B5.

My main concern is the 1.8t motor sitting on the 2.8 / S4 k-frame, is the engine mount spacing the same, since the 6 speed tranny sits on two low mounted mounts I need to have the motor on the other frame, that or rig up a mount to make it work, just trying to get ideas.

Looking to build a full 2.0 block with the AEB head out of my car and a 35r or 3076. [:D]


Note: I am not even remotely considering a 2.8 5 speed, 6 speed or bust.

That car only looks good in ultrasport imho

I just saw a B6 6MT trans sell on ebay for 300 and 100 shipping. The B6 has a different final drive and/or rear end ratio, I can't remember which. I looked it all up in AW's reference library when researching the swap.

I don't even remotely have enough money to put a VR6 in a B5 chassis, the amount of work thats required is fucking crazy. The custom brackets for just about anything everything are expensive enough. Seeing I'd need to make them or source them from 034.

my buddy with an 01 s4, who had a b5 a4 said he thinks the 6mt out of the s4 is sloppy compared to the a4 5 speed....... i on the other hand think that the 5 speed runs out of life too quick compared to the s4...... his solution could just be a short shifter and different linkage, but i could be wrong


maybe find a 04 1.8 that has been smashed and swap that in


also wouldn't you have issues bolting up a s4 6 speed to a 1.8? there would be fabbing involved there.... just throwing that out

I am sure people have done it, but B6's are cheap... The S4 tranny isnt the best ratios either (first and second are just as short as the 1.8). Idk about the B6 ratios. I understand about the weight issue, but with the hassle of swapping a 6 speed in a B5, I dont think it is going to be worth it.

Bell housings are identical.

What is needed to swap in a 6spd S4 tranny:

S4 drive shaft, rear differential and axles, not to mention a 2.8 / S4 sub-frame or get a custom bracket made for the A4 sub-frame.

My only concern right now is a 1.8t motor sitting on a S4 subframe, the rest is a cake walk. Its not necessary but buying a 2.8 subframe would be a lot easier than fabbing up a bracket, though I think 034 may have some? Not 100%.

This has been done before but with front track, which makes it quite a bit less complicated.

Am I missing the point of this comment?

We're talking about transmissions that use the same housing. The 'heavier' B6 is heavy elsewhere. Not in the trans.

The transmissions are the exact same between the B5 and B6 A4s. The only thing different is the front driveshaft flanges, tailhousing and gear ratios within the trans.

My B5 Avant weighs 3400 pounds so weight isn't that big of a deal. The B6 also has a larger and nicer interior and can fit 255 width tires easily.

The B6 trans sounds like your best bet. If it is indeed just the transmission and rear end then it sound pretty easy. I don't know about the shifter linkage though.

Here is a link to the auction that just ended. There are a few on there from time to time. I almost bought this last one but wasn't sure how much extra work I was getting into.

Someone suggested I get a B6 period because it had a 6speed, hence why I mentioned that I wouldn't want a B6 chassis.

I dunno if the b6 is straight bolt it, doesn't seem like that to me, I wouldn't want to buy a tranny only to find our that it doesn't bolt up.

I missed that. I'm thinking along the lines of you using a B5 S4 shell and putting a 1.8T in it and want a 6spd transmission. Hence why I was confused.



I dunno if the b6 is straight bolt it, doesn't seem like that to me, I wouldn't want to buy a tranny only to find our that it doesn't bolt up.

If you have a B5 A4 with a 5spd. I am confident the B6 6spd will bolt right in. You'll have to use your B5 tailhousing and front driveshaft flanges. That is all Clint and I have done to put a 2.8L 5spd in our B6 1.8Ts. We re-used our B6 tailhousing (its got the crossmember hook-up) and front driveshaft flanges. The shifter linkages are also the same.

If you have a B5 S4 chassis with a 1.8T in it: I'm not sure if the S4 driveshaft is the same length as the B6 A4 driveshaft (or B5 A4 for that matter). So, I'm not sure if you'll have to monkey around with the driveshaft when trying to install a B6 A4 6spd into a B5 S4 chassis. The rear differential ratios are also different so that will throw off your gearing (depending on what your final gearing is looking to be). Might want to talk to Jay@JHM about the B6 6spd and B5 S4 6spd differences. My gut feel is he'll say they are the same transmissions, just slightly different gear ratios (if that). You also want to get the entire shifter linkage with the 6spd. They are completely different between the 6spds and 5spds.

All 5 speed trannys, 01A, 01E and 01X have multi-bolt pattern, and will fit 4, 5, V6, V8 and V10 motors.

All 6 speed trannys from the same family as listed above will also fit all the above engine configurations.

The 01A 5 speed was fitted to all B3 and B4.
The 01E 6 speed was fitted to S2, RS2, C4 Ur S4 / S6, C5 A6, B5 S4 / RS4, D11 V8, S8.
The 01X 5 & 6 speed were fitted to B6 / B7 A4, C7 A6.

The 01X tranny is lighter than the 01E, the cast iron central casing the 01E came with is light alloy on the 01X.

The 01X also has a different front / rear bias on quattro models.

Siena
06-10-2008, 12:24 PM
Driveshaft lengths are the same.

I fitted RS4 uprights, hubs and brakes to Docurley's widebody 1.8 TQS 3 weeks ago, and I replaced his 5-speed driveshafts with the RS4 items, which have the larger inner flanges.

The flanges are the same size as FWD V6 models, quattro models, excluding S4 / RS4 have smaller front flanges. The lengths are also the same.

When my 01E 6 speed goes into my B5, I'll be fitting FWD V6 driveshafts.
I also don't need to replace my rear differential, as the ratios in my current set-up is the same as the S4 / RS4 @ 4.11:1.

Siena
06-10-2008, 12:32 PM
I also fitted the 01E 6 speed to my RS2-powered type 85 Coupe quattro (US 4000 quattro) back in 1999.

Besides running a SM flywheel, making up a couple of custom mounts, and running driveshaft flange spacers, (the OEM 016 5 speed box is wider) it was an easy conversion.

safab
06-10-2008, 12:33 PM
I believe all you need for a s4 6spd conversion in a b5 is a transmission, driveshaft, and rear differential. Axles should bolt right up.

As far the motor sitting on the subframe...it doesn't sit on the subframe...only the transmission sits on the subframe. The motor sits on mounting hardware that is bolted directly to the frame of the car...I've personally swapped subframes back and forth on a FWD passat with one from an S4 and it bolts right in.

Shameless plug:
And I happen to have all that for sale including a subframe and rear brakes/spindles if needed...

I also failed to mention that I will have S4 uprights on the car. Just like on my previous car, to run those I need S4 axles or like on my car, 2.8 axles which bolted up to the 1.8t tranny. This is primarily why I am leaning towards the S4 tranny,

Thank you for the Info Siena and Dougyfresh, very useful.

The insurance company is trying to crazy low ball me, offered me 6,100 for my car, so it'll be a matter of weeks before I get any money out of them if I'm going to have to file a lawsuit.

Really can't believe no one has put a 6speed quattro tranny in a B5 before. I need to look in at the cost of the rear differential out of an S4.

Siena
06-10-2008, 01:19 PM
To reduce cost, I'd be looking at V6 quattro rear differentials.

Looks like I was wrong. The only odd one is the B5 S4. The 2004 A4 didn't have gear ratios shown so I had to use the 2006 A4 3.2 FSI.

Good info. Here is another little chart I put together a little while ago, while on the search for better gearing. My conclusion, after speaking to SEVERAL people who've run different transmissions with the 2.7T and kept breaking them because the gearshafts simply couldn't take stage 3 power, was too just keep the stock S4 transmission and go with a JHM rebuild (mine had failed synchos).

http://i28.tinypic.com/seyfs0.jpg

I heard great things about the allroad tranmission, as the housing featured fittings for an external oil cooler, audi used it from the factory with their 4.2 and 2.7t motor, it seemed like a great option. Although upon looking at the gearing ratios and tremendous price (~3g's!!!), I quickly strayed away as it would not only yield lower speeds at the top of each gear but I would still be buying a used tranny not really knowing the condition of the synchos.

Next I thought about using a B6 A4 3.0 transmission, as I noticed it had the same ratios as the RS4 tranny and could be had at a fraction of the cost. At the time I found one for about $1,000 in good working condition. This seemed like a great route as well, especially after finding out that 1-4 gear ratios were the same as RS4 and would give me just enough to shift and get going into 4th before going through the trap. But then I contacted Stasis, where I was informed that although the ratios may be the same the gears themselves were weaker than the B5 S4 gears and I would more likely than not, break them with enough abuse and power that a stage 3 car could put. This really explained to me why one particular friend who has tried numerous transmissions in his car kept breaking them time after time. Its was not the driving, but the transmissions themselves. It was also noted that most of the A4 transmissions had the same shafts and gears, which all would eventually fail stage 3 power, the only exception was the B5 A4 2.8 transmission, which would be the strongest of all the A4 transmissions and give the best ratios, although it would be a 5 speed, a bitch to drive on the highway yielding terrible fuel economy, but still not stronger than a B5 S4 transmission.

At about that time, I saw Jay was in the process of having gears made, although again the price they were being offered IMO would not justify the gains, considering I would still have to rebuild my tranny as the synchros had failed. For me, in the end I did my homework and decided the cost-benefit of any other options would not justify the gains and possibility of having another broken tranny so I just went with a standard JHM rebuild kit and kept the ratios I had.

Maciek, for you, if you plan on sticking with the 1.8t and depending upon how much power you are planning to make, if you are seeking a 6 speed it may be worth just snagging a B6 A4 3.0L 6speed tranny and using that, although based upon the discussions I've had with others and the outcomes we've seen with the experimentation of different transmissions other than the B5 S4 6speed with the 2.7t platform, I'd say the B5 S4 transmission is the most bullet proof option out there. As far as the B5 S4 trannies are concerned, it should definitely be noted that the 01.5-02 synchos were updated and will be less prone to failure over the 00-01 revisions. Otherwise, make sure to do your homework.

p.s. - Coming from a B5 S4 standpoint with a 4.111:1 final drive and matching rear diff to any of the transmissions mentioned, the only one that is completely plug and play would be the B6 A4 3.0L 6speed and ofcourse a true B5 RS4 tranny, which we will almost never see here in the states. The Allroad transmission will require an allroad rear differential and the B5 A4 2.8L 5speed transmission will also require a matching a rear diff, axles, and spindle.

So is there a final drive discrepancy here or not? I couldn't find info on a 2004 3.0 6MT which your chart shows a B6 3.0 6MT has a 4.111. The AW chart shows a 2006 3.2 FSI 6MT is a 3.889.

If both sources are correct then the 3.0 6MT shares the S4's ratio and the others work with our 3.889 which opens up a lot more model years to borrow parts from. [wrench][up]

If you are looking for a strong transmission the RS2 box is legendary as pure bulletproof unobtainium. [o_o]

Sarge on AW runs 600hp on 91 and says his 3.0 big turbo allroad has the potential for 900 on better brew. I don't know if he beefed it up or if the allroad box is inherently strong. That higher final drive offsets the taller tires and additional heft and could be interesting in a lighter car.

Just a little related food for thought. We all know the 2.8 box has slightly taller gears than the 1.8 box. The difference is about 6-10% which is pretty much the same as swapping the 225/45-17 stock tire size for a 225/50-17.

Plz explain the clutch setup. Are you running a 1.8t fly+clutch w/o the spacer that is used for the s4? Pics would be nice.

I wonder how many MPG gain should be expected on the highway w/ the 6spd...I checked out one of those gearing calculators and the s4 transmission will run ~500 RPMs lower @ the same highway speed:

1.8t clutch and flywheel are needed, I am getting around 400 miles a tank as opossed to the 300 to 320 from the five speed. I am running a Diesel passat box and in 6th @ 80 its under 2700 rpm iirc

mawhitey.. those are similar miles I was getting. I think iw as averaging around 360 a tank but thats of course 75% easy driving and 25% aggressive driving.

I too am running the 1.8t clutch and flywheel. The throw out bearing is from a 1.8t as well.

I can get pics if needed, literally the transmission is in open viewing area for the next week.

Thanks for the feedback guys...I'll probobly be installing in a month and a half and am looking forward to the mpg improvement since this is my commuter car :)

Wow awesome, Some pics would be awesome Beemer or Mawhitey.

Can you post a list of all the parts you put in?

Next I thought about using a B6 A4 3.0 transmission, as I noticed it had the same ratios as the RS4 tranny and could be had at a fraction of the cost. At the time I found one for about $1,000 in good working condition. This seemed like a great route as well, especially after finding out that 1-4 gear ratios were the same as RS4 and would give me just enough to shift and get going into 4th before going through the trap. But then I contacted Stasis, where I was informed that although the ratios may be the same the gears themselves were weaker than the B5 S4 gears and I would more likely than not, break them with enough abuse and power that a stage 3 car could put. This really explained to me why one particular friend who has tried numerous transmissions in his car kept breaking them time after time. Its was not the driving, but the transmissions themselves. It was also noted that most of the A4 transmissions had the same shafts and gears, which all would eventually fail stage 3 power, the only exception was the B5 A4 2.8 transmission, which would be the strongest of all the A4 transmissions and give the best ratios, although it would be a 5 speed, a bitch to drive on the highway yielding terrible fuel economy, but still not stronger than a B5 S4 transmission.



There is no difference in the gear part numbers or strengths between the 2003/2004 3.0 6 speed gears and the RS4 gears, they are the exact same part.


So is there a final drive discrepancy here or not? I couldn't find info on a 2004 3.0 6MT which your chart shows a B6 3.0 6MT has a 4.111. The AW chart shows a 2006 3.2 FSI 6MT is a 3.889.

If both sources are correct then the 3.0 6MT shares the S4's ratio and the others work with our 3.889 which opens up a lot more model years to borrow parts from. [wrench][up]

If you are looking for a strong transmission the RS2 box is legendary as pure bulletproof unobtainium. [o_o]


The 2006 3.2 manual 6 speed gearbox is an entirely different transmission than the 03/04 3.0 6MT no parts interchange. The 01E did have a 3.889 final ratio but it's europe only and was used in 2003-2005.

There is no internal difference from the RS2 gearbox and the 03/04 6MT 3.0 6 speed, aside from a diff driven oil pump.

I recently did a 6 spd swap on my 1996 b5.
got a b6 1.8t trans (4.11), s4 b5 front shafts and a full s4 b5 rear suspension.
I had to shorten my main driveshaft 20mm (+- 1") and fabricate trans mounts.
now 15 000 (track) km on 473 whp (aeb) and still no issues.

hope this was helpfull?[:d]

Why do you guys want 6-speed? I don't get it school me.

I know that Mike Hood (Mike2ptzero), utilizes the 01A on his 600+hp drag car. If anyone would have thought it would be reasonable to jump to the 6speed for performance reasons I'd think it would be him.

From my understanding the 01E have a tendency to destroy 1st and 2nd gear synchros and are three times the cost of an 01A tranny. The 01A's are known to be weaker, but at $300-$600 for a used replacement or $1K new, it's more economical just to replace it once it dies.

Your right the 01E does have syncro problems, but those problems are fixed in the transmissions we offer as overhauled units, or the parts kit we offer here for $895.00 (http://www.advancedautomotion.com/product_info.php?cPath=69_52_142&products_id=88).

I guess it's a matter if you want to do it right the first time or keep doing it over. After 3 transmissions replacements @ $600.00 plus time plus lost use of the car, plus your wife bitching at you because your taking up her space in the garage replacing the transmission, your in the cost of what an 01E would have cost you. I have a customer in NYC that went through 4 01A's in his big turbo A4 before he went 01E. He could strip first gear of all the teeth consistently by launching at 4000 rpm.

BTW I heard Mike has been through a few 01A's already.

hit up raven motorsports there shop car has a 6spd in a b5, and a bunch of other prototype goodies but the car is baddass they can do it and tell you what all needs to be done, i think it is out of a s4 and with mild changes will bolt up!!!

I'm a big proponent of Do It Once & Do It Right, hence some of my modifications. I'm just saying the 01E isn't as "bulletproof" as many think. As far as the cost/performance ratio on an 01E vs. 01A, we could debate. But $900 for just parts, plus install labor of those new parts @ 3hrs x $80 = $240, for one ready to go transmission. I'm not going to count labor to pull the tranny out and re-install, since you'd have to do it anyways for both.

Well like you said that's two or three 01A's for the price of one "better built" 01E and there's no guarantee that the upgraded 01E won't give out.

And yes, Mike has gone through several 01A's and usually has a spare 01A in the garage. There was some speak of getting hardened gears for the 01A, but the cost wasn't justifiable, since it's just easier to swap out the trans.

Hey, how do you know about my wife.[>_<]

The record thus far for one of my gearboxes with treated stock internals is 800 horsepower. I've got a dog box 01E with 950 CHP not including the 250hp shot of nitrous winning races in Eastern Europe.
No failures after 2 seasons. That's probably as bulletproof as you can get.

Yeah, if you heat treat/harden gears in any transmission (01A or 01E) it's going to be stronger.

Replacing the OEM tiny gear teeth and all of the other tiny parts with straight cut gear teeth that are larger and exponentially stronger, will be able to hold more power.

Once again if you make the above mentioned modifications to just about any trans, it's going to hold up to a big beating. But I though we were talking about 01A vs 01E?

The main problem with the 01A it in it's design, the main gear cluster is unsupported whereas the 01E/01X/0A2 there is a support bearing in the middle of the gear clusters. Excessive torque will cause the 01A shafts to deflect away from each causing the gear teeth to mesh further away from the tooth root, and then teeth start to shear off, it's a design flaw inherit to that gearbox.

I'd say the 01E torque limit is 4 times the 01A on stock internals, and 6-8 times on custom internals. I've have yet to see and 01E strip teeth.

Good morning. Quick question for those who are running 01E on their 1.8t did you guys use the spacer plate? I'm running a Clutchmasters Fx400 with a bigger flywheel and clutch assembly. I just installed a 01E and didn't use the spacer. now the engine doesn't want to turn over...

Yes you must use the spacer, your clutch choice has nothing to do with it.

08-03-2011, 08:34 PM
This problem has been encountered before. It happens when you use the larger 240mm clutches on the 01E without a spacer (smaller clutches don't seem to have the issue).

Please see this thread. Problem is first referenced in post #669 (page 17) and problem is successfully fixed in post #789 (page 20).
