6.0 LS2 with Built ZF 5hp19FL???

[GMguy]

I'm new to the forum, and looking for additional information. I am doing a Mid-engine GTM supercar http://www.factoryfive.com/gtmhome.html (give you an idea of the engine/trans layout) and instead of doing the normal Porsche manual mated to an LSX engine, I plan on using an automatic trans. From a ton of research I have done, looks like the 5HP19FL is almost the perfect candidate. I realize this trans is factory rated at 300Nm of Tq used in everyting from 1.8-3.7 V8 engines, but all of the factory vehicles seem to weigh in around 3500-4000lbs, while GTM weighs 2500lbs with driver.

As far as gearing this is what I have, and interesting enough I have found 3 different Final drive ratios. trans code (green label on trans) EZS, DDT, EFP = 3.73 final. DPS, DRD = 3.41 final. And EZZ, CJZ = 3.09 final
1st 3.67 : 1
2nd 2.00 : 1
3rd 1.41 : 1
4th 1.00 : 1
5th 0.74 : 1
Reverse 4.10 : 1

It seems several shops (Trans specialties, IPT, 517) build this transaxle and I have heard 700hp is roughly the top number it can be built up too? I am shooting for around 480-500 to the rear wheels again vehicle weight in my advantage as well.

An adapter seems like it should be pretty easy, I can either build one myself or possible buy the existing Audi 5000-LSX adapter (It appears to share the same bellhousing from pics)

The Tq converter I can approach from a few directions and here I am a little concerned. The 5hp19fl Tq converters dimensions are 9 1/4 bolt circle, diamter 10 7/8, 3 mounting pads (which all is great), but its OAH (overall height from hub to mounting pad) is only 4.380, not a lot of room in there to really beef this thing up with clutches and all IMO? Another option is to use the 4.2 liter Quattro converter (IF POSSIBLE??) which has an OAH of 5.670which is pretty close to what the 4L60E is. Last option and most expensive (about twice as much) is to use a 4L60E converter with the Audi pump and hub (27 spline) welded to the GM converter. This way it will bolt on without any modifiing. Otherwise 3 new holes need to be drilled in flexplate and a adapter over the pilot to fit snug on the crankshaft (no big deal really, mainly worried about them being strong enough).

Controlling it I plan on using the PCS trans control, last time I checked they offer it for the 5hp19 series trans, so getting this to work with a GM engine wouldn't be a big deal. Anyone useing the PCS on here?

Shifter I plan on using probably just a Passat (same trans as the audi) factory shifter with a custom cable (longer) since the trans is cable shifted.

Ive reseached this topic and it seems that with a converter upgrade this trans can take a bit of a beating?
Opinions?? Advice??? info seem correct??

also, if you are a building a car that sick, wtf do you want an automatic transmission for!?

Because he is a pussy.

And this is the worst spam of all time. Most people interested in a kit car, know what they are going to go with. Your not going to catch any impulse buyers here.

Really, lots of diesel guys run automatics cause they are faster then manuals.

[nofearhawk]

Why don't you give sam at 517 a call. His built transmission with upgraded tc should handle that hp and if not I'm sure he can whip up something custom for you.

The Shelby Cobra Super Snake was an automatic and it was the manliest car of all time.

[ZimbutheMonkey]

In the slight chance that this is legit, let me answer for you NO DO NOT USE A 5HP-19!!! It cannot be built to take the stresses that a V8 can generate end of story. Find a transmission from another vehicle and send me something nice from the $10,000 you'll save by not going down this route.

[pape]

I would advise you to first go (fly) to some one that has a built GTM and sit in it, go for a ride and if possible drive it before you buy one.

who will be building the GTM???

I know the idea af a 2500lbs corvette sounds nice but this is a costly project and you should know what your geting your self into... $35,000 or more deep...

[GMguy]

All different types of opinions in here [:)]
Razarbacks played pretty good the other night I thought.


also, if you are a building a car that sick, wtf do you want an automatic transmission for!?
All the fast cars have auto's. I have a 4th gen F-body with a D1 procharger, Fab 9, and a 4L80E that makes 850hp. Driven many C6 vettes with the 6L80E trans making 600rwhp, and loved it.


And this is the worst spam of all time. Most people interested in a kit car, know what they are going to go with. Your not going to catch any impulse buyers here.
Impluse buyers? Don't plan to sell it, but many people would love to have a supercar with an auto IMO.

I talked to him a few weeks ago, great guy knew his stuff. 600-700hp is not out of the question for a properly done 5hp19fl, Tc seems to be the biggest issue, probably due a Hybrid 4L60E/audi converter.

I dunno, seems like stage 3 cars make 370whp/440wtq on stock trans with upgraded TC and tip mod (PCS controller will be a ton better than that, also better than a valvebody IMO)

I have about 60 grand in my 4th gen F-body. I can do a GTM the way I like for around 45 I believe, nothing crazy like my Trans Am. I like the idea of a high end kit car, built the T/A can built this thing.

Thanks for the replies

[seanj130]

Is this thread legit?

[pape]

I wanted to build a GTM but its just too much time, lots of money, space is needed, and extra cash for shipping the cars and parts, and the body finishing and painting. at the end its still a kit car.
mabye in the future....

but sounds like your ready for this. I always liked the idea that the GTM chassis could be built and moded to be one of the fastest street cars in the world....

[juxsa]

Unless you are wanting to make an AWD car why not use the T56? Its a great tranny with one of the best gear ratios out there? And it should bolt right up.

[GMguy]

T56 would bolt up, but I need axle flanges out the side of the car not front to back. C6 vette setup is too long, axle flanges need to be roughly 9-10 inches back from bellhousing, auto vette is roughly 15-16.

Not plan on making it AWD, the FL version is a FWD, but plan on putting it in the rear (still turning same direction however)

[blacka4]

I don't see why it wouldn't work and be fine.

[juxsa]

I would also check out VWvortex.com also. This forum is pretty informative about our specific cars but I doubt many people here are going to be able to help because I doubt they have detailed specific knowledge that your looking for. In fact I would be willing to bet you know more about these transmissions than almost any one else on this forum :-D Either way, even with weight of the car being almost 1k lbs lighter than an Audi, I would be weary of it being able to take the torque the LS2 produces with out grenading after a few launches.

I have talked to ZF, many Trans shops, etc. Many people talk about how the V8's make so much more tq, and stock LS2's make around 350rwhp 350rwtq. The stage 3 guys with 20+psi make around 370whp/445wtq so thats a lot more Tq than what I have in factory form and some are doing that on a stock trans with just a TC upgrade and tip mod, funny since this trans was only rated to around 228ft/lbs. I do plan to mod it, but nothing too crazy. Not alot of info out there on these trans, seems only a few shops build them, and with that seems like many of the hard parts are just OEM?

[ZimbutheMonkey]

In response to the OP, stage 3 S4's also frequently blow transmissions. You may have some better luck with the 5HP-24 that came in the later year (2001+ IIRC) S4's. As for running an upgraded TC, yeah that may help up to about 300 WHP, but past that it's still a bit of a crapshoot. As for the PCM controller, I looked into it about 2-3 years back when I had a tip. However you're going to spend a lot of time trying to fine tune it, that is if you don't blow it up first. Believe me, the 5HP is a very very fussy transmission. I had one on my GT 2860 and after an enormous amount of research into how feasible it would be to keep it finally gave up while I was ahead in favor of a 5 speed conversion when I realized that short of a $7000 overhaul there was no way to guarantee that it would stand up over the long run.

Also, regarding the PCS controller helping to hold the torque, it isn't going to do you a whole lot of good. When I overhauled the 5HP-19 valve bodies on my folk's Boxster I spent a lot of time on the phone with the ZF North America service manager. What he told me was that the valve bodies on the 5HP series are very compact due to the complexity of the transmission. As a result, they rely on using a lot of pressure to actuate comparatively small pistons. In your case, what this means is that there isn't a whole lot of line pressure to spare above and beyond what it takes to actuate the pistons on stock settings.

Anyway, take that for what it's worth. If you really want to try it out I've got a FWD 5HP-19 with 40,000 mi on a rebuild and an upgraded IPT TC that you can have for $1000. http://www.audizine.com/classifieds/showproduct.php?product=37387&title=ipt-torque-converter-and-ddt-code-1998-front-track-tip-transmission&cat=20 You're not going to find a working 5HP-19 with that low of a mileage with an upgraded TC for that price anywhere else. So if you seriously want to try this PM me and I'll be happy to sell it to you.

[JoshDub]

Impulse buyers for what?

The kit cars.

If this isnt spam im sorry, but seriously what the hell is this thread when is has nothing to do with the B6?

[AudiA4Turbo22]

I also have a 5HP19FLA AWD tranny if you want that. Bone stock it's yours for $600

[diagnosticator]

Why have you decided the 5HP19 is the trans to best suit your custom application? Why not go with a 5HP24, or a 6HP19? both of these transmissions are rated for a lot more input torque than the 5HP19. BTW, AFAIK, the input torque rating is after the TC, @ 3000 RPM.

[dowsett6]

You can't just compare the TQ numbers back to back like that. You also have to include where the TQ is actually starting in the rpm band. Sure it can handle a 1.8t's big turbo torque as it is higher in the band already spinning pretty good. Your LS2's torque is basically going to be instantaneous which is where the problem actually is.

[black99.5a4]

if you're wanting to keep with audi branded trans that will handle the power.. idk why, but 01e from the s4 is your best bet. 01a's will blow up on you quite often.

[Sales@RAI]

There's no way I'd ever run an auto Audi trans on any performance car. Look back at the stage 3 S4 guys that have spent $5k+ only to have them blow after a few months, that'll change your mind

[a4darkness]

How is this still going? Seriously. He's trying to sell kit cars.

/thread

[GMguy]

Very true about where the numbers are happening at what RPM. Some of the
Sage 3 graphs I have seen power numbers peak around 3500 in Tq and rev close to 63-6500.

The LS2 or any LS engine without boost makes a similiar curve usually tq peaking at 4500 rpms. I had a maggie LS2 vette that did however make 450rwtq at 2500rpms,
but that was with boost

What is the O1E or the O1A? Is that just another name for the trans?

[ZimbutheMonkey]

Did you see my post in the B6 version of your question? If not check it out.

Thats an awesome offer, but right now I am still in the research stage. I have a TCI box that controls my 4L80E trans in my 4th gen Fbody. The principle of the 5hp19 is basically the same method of tuning using the PCS box. Thougth about the 5hp24A was its an AWD trans that splits the Tq from the front and rear differential, didn't know how that would effect anything considering I am only using the frotn axle part. Also that trans is very long (could remove rear housing though). I figure they run off the same principle mechanics as the 5hp19 but I am no for sure (maybe no PCS support?)

I looked into the 6hp series trans, if I could I would go with the 6hp32A setup but it operates off a CAN BUS system similiar to the 6L80E trans from GM, NO aftermarket controllers for those yet, will be awhile too I assume.


How is this still going? Seriously. He's trying to sell kit cars.
WHAT? I am trying to find info about this trans to put into a GTM for MYSELF. Not selling anything here

[GMguy]

Yes I did, thanks for the info

[ZimbutheMonkey]

You may be able to adapt a 5HP-24. It's a very similar transmission. If you're going standalone that eliminates the ECU/TCU freakout issue. You do have a leg up having tuned the 4L80E, however I'll say it again, these transmissions are nothing like a 4L80E. Here's a torn apart 5HP-19 valve body as an example http://www.audizine.com/forum/showthread.php/376009-Crash-course-in-5HP-19FL-surgery-mit-pics?p=5546813&viewfull=1 Not trying to say that it'll never work. I'm just trying to give you a real assessment of what you'd be getting into.

PCS has CAN 2.0b available on all of the trans controllers they offer.

[CoreyRS]

I have never seen a thread more over my head than this.

[GMguy]

Sorry I haven't posted guys, my computer has had a virus. I have been looking into the 5hp24A trans, and it appears I can just remove the rear housing and make it a 2wd transmission?? I don't know if it is as easy is that though, this shows a pic of the rear transfer case removed http://tomboynton.com/Audi.html
The 5hp24A also has a much larger TQ converter (feel a lot better about beefing this unit up too, opposed to the 19FL)
Looks like the higher powered RS6 uses a slightly modded 5hp24A (beefed up Tq converter, higher line pressure) so I feel confident we could do the same with some teaks. I have also heard the ring gears in the 24A are the same size as GM's 3/4 truck (strong units)

I contacted ZF and got the Transmission pinouts and about 98% are the same for the 5hp19FL and 5hp24A, so trans control should work for both.

Something I am rather confused about since I don't deal with 4WD transmissions is the final drive (either 2.72 or 2.91) is that within the trans itself or in the rearend or both? Again I need this transmission to function as a transaxle no room for a rear end in my app.

Here are the weights of ZF's hp19's and 24's
5hp19-174lbs
5hp19FL-242lbs
5hp19FLA-312lbs
5hp24A-312lbs
5hp24-209lbs

From looking at pics it appears the 5hp19FL and FLA are identical besides the FLA has the rear housing added to it, they also have the same rebuild part number. So it would make since I could remove the rear housing on the 24A and make it work like a FWD and hopefully weigh in around 250lbs opposed to 312??

[GMguy]

PCS can support some CAN Bus systems, but they can't do any Zf 6hp series transmissions or GM 6L series, I called about that already.

[GMguy]

Guys any help?

[diagnosticator]

Yes, the rear housing with the center torsen diff can be removed, but then a different housing will need to replace it. The Axel ratios are for the internal front differential and the rear Axel differential ring and pinion ratios. the center diff does not have a ring and pinion, and you are removing it anyway.

Opinions?? Advice??? info seem correct??

The 5HP19 is a good transmission but even the "built" ones can exhibit issue after 500 hp. 700hp is almost a guarantee for failure. For an automatic you really need to be looking for a 5HP24, however I don't think the FWD 5HP24 came to North America, I do believe it can be found in certain European diesel models. An even better choice would be the 5HP24 from an RS6 with the rear drive section deleted. The RS6 version of the 5HP24 had a much large torque converter (11.5 inches IIRC).

The Audi ZF gearboxes have a set of gears that transmit power to the front diff from the rear of the transmission, and by changing those gears you can change the overall drive ratio and not have to purchase or make an expensive crown wheel and pinion. IIRC pretty much all the Audi 5hp19 gearboxes have the same internal ratios, it's the final drive and transfer gears that differ in ratio.

Another thing to consider is an automatically shifted manual transmission. The 01E manual gearboxes can hold up to a ton of power and there are a few companies that offer automated shifting computers with paddles and the like for a number of gearboxes.

[GMguy]

diagnosticator are you saying when I removed the rear housing I can just make an aluminum plate to cover it or some type of gear setup needs to be added??
Scotty thanks for the reply as well, I know the RS6 used the same internal 5hp24A but like you said a larger Tq converter and if I am not mistaken more line pressure. As far as the TQ converter goes the standard 5hp24A in the 4.2's used around a 10 7/8 to 11 inch converter, I figure it has more to do with internal mods than size? Look at all the small 8inch TQ converters used in high hp drag racing applications. As far as I am aware ZF never made a FWD 5hp24 only the RWD 5hp24 and the AWD 5hp24A which is the one I am wanting to use, just wondering whats involved in getting it to work as a FWD.

I have looked into the manual shifted automatics, in fact I have a 4L80E in a procharged TA that uses a paddle shift system, but I like the gearing of the 24A and 19FL much more.

I know the manaul guys that have AWD transmissions talk about removing the rear housing (transfer case) and welding up the center differential, does the same have to be dont to an automatic or can I just removed the rear housing, bolt up a aluminum plate to enclose it (I can make that) and the trans would transmit all the power to the front?????

[GMguy]

BTW just found this accoring to my source
RS6 converter- Diameter 12inches, 10 1/8 bolt circle, 5.685 hub to mounting pad distance (OAH), pilot size .629
4.2 Audi quattro--Diamter 11inches, 9 1/4 bolt circle, 5.670 hub to mounting pad distance, pilot size .629
6.0 Phaeton used a 12inch converter

Of course all 27 spline

[GMguy]

Here is a cutaway of the 5hp24A aka o1L transmission http://www.audipages.com/Tech_Articles/auto_transmission.html im not a transmission guru but I am wanting to delete everything behind to 2 large gears in the back, or would more need to be deleted? Hoping I can just delete the rear housing and thats all?

[GMguy]

Hope I can get some clarification?

Looked at ZF for the 5hp19FL and FLA and they use the same rebuilt kit and I looked at every page in the manual and even the internals are all the same, only thing different is the rear housing, which now I know houses the Center differential. For some reason I thought the center differential was located else where. Almost like the AWD system was an afterthought from the FWD unit.

This tells me the 5hp24A can do the samething and delete the rear and make it FWD, no more center differential.

You will have to get a new set of transfer gears manufactured as the FWD versus AWD gearsets are different. On the AWD boxes power is routed through the output of the transmission to the center differential then to the transfer gears. The FWD version the output of the transmission is routed just to the transfer gears.

It would likely cost $2-3,000 to have new gears manufactured.

[GMguy]

Man thats not what I wanted to hear considering the 5hp24A seemed up to the task as far as my power goals. Scotty did you ever look at this webpage http://tomboynton.com/Audi.html

The transfer gears are the 3 gears near the back of the trans correct, directly before the center differential (from bellhousing back)
Ultimate goal is roughly 480rwhp 440wtq

[Scotty@Advanced]

Yes the output shaft of the transmission goes through the top gear to the center diff, and the center diff in turn attaches to the outside of the top gear. You could make a splined adapter of sorts to join the gear and shaft together, however there's still a major investment to manufacture that part, you could also weld the output shaft to the gear but that would for all intents and purposes make the transmission disposable in the event it needed internal repairs, plus welding case hardened parts together is always a bad idea.

Bought a 5hp19FL off an 01 2.8 GLS with 30,000 miles and converter for $290, also got a shifter/n cable for $43 shipped. Cable is way to short but I can config something to work. Going to have ACE converters do me a high end converter (same as EDGE racing who does a lot of Domestic converters) and I can actually trust these guys, converter only cost $424. Talked to Russ (owner of PCS) and a controller and harness from them is no problem, even set me up with a base tune. Alot of porshce guys use this box with there 5hp19's, maybe get in contact with some of them? I can buy an aluminum 1/2 to 5/8 thick plate for $100 so I can make an audi to LS adapter plate.

Interesting setup if it works... [cool]

Funny how price is always tantamount to wise provisioning of components.

Another problem is the tiptronics are much wider than the manuals and depending upon your setup can create some pretty nasty cv shaft angles. If you don't put a kit in that transmission all of that work will be for naught, stock clutches don't last long under that kind of power, and the thing about the zf transmissions, it's not use but time that degrades the rubber piston parts. Also you need to replace the 3rd gear drum, it was defective from manufacture on all 5hp series transmission to 2003.

Only mentioned price because I got a really good deal

Cv angles shouldn't be an issue, plenty of room in the back to line them up to the rear wheels. I believe the axles flanges are 108mm so I can use 930 style axles (a shorter axles will be needed, but again, angle wont be an issue) believe there operating range is up to 25 degrees, be well within that. Never had trouble with any trans sitting for any time period, as long as there is fluid inside.

Scott what do you mean by kit? Don't see why this trans wouldn't work as is, if there is issue I can pull it out and have it rebuilt. Plan to do a Tq converter upgrade and Valvebody first and see how it goes.

How are you going to upgrade the 5HP19 TC and Valve body, is it going to be DIY? [cool]

[GMguy]

Ill have ACE converters build the TQ converter up, and have either 517 or IPT do the Valvebody. Both can be installed by yourself. I was looking at the Trans yesterday, may be easier to just cut the existing bellhousing off and weld on an 4L60E housing

No CV flanges are 130mm tripod style.

Pump more than 350 ft/lbs through a stock 5HP19 will result in slipping clutches. Even build 5hp19's are pretty well documented to start slipping at > 450 ft/lbs. A kit is an overhaul kit. Not to mention the diff (IMHO) is way too weak to handle the full brunt of an LSX V8 engine. In a quattro gearbox, the front diff never sees all the power in a FWD box the diff sees all the power. This will be an interesting and likely expensive experiment.

[GunSupplier]

Did this expensive experiment ever happen? I wonder what happened to GMguy. I kind of wanted to see an LSX decimating a 5HP19...haha.

Scotty, you need to give details about your secret underground 5HP19 Tial project car! [:D]

[Elizabeth1979]

I think the lesson here is to be wiser when picking a car. It is not a candy that we buy in the grocery. Cars are expensive stuff so we have to choose what's really fit for our style and budget.

Hi,

Not sure how you went or did but I'm interested to know if you or anyone else has been successful in controlling a 5HP24 with a PCS TCM-2000 aftermarket TCU?
