    If you guys can shed some light I'll keep trying what I can to find some more avenues. I'm not in to the be patient motto.
    Who makes the actual TCU components? Who actually creates the transmission software? Is it Kostal?
    any other companies that are contracted by BMW to develop hardware and software for trans control?

    @R.G. I honestly don't know who makes the software but it would be nice to know. I don't know of any brands, I just know ZF makes the trans and I think BOSCH the DME/ECU/TCU. Software no idea.
    @07Tundra was contacting that softelectronics, that should have been awhile ago now,any word Jose?

Currently we offer only repair for the 6HP used in VW and AUDI." In other words, we go nothing.

    I'll keep researching this evening. If I know who actually develops the software and processors we can work backwards, instead of trying to crack the encryption.

    Good to know Alex. Honestly, if I were to bet who would ultimately resolve this I would have wagered ABR. If I can help with anything on the research end of things consider me free labor. I can usually dedicate a few hours in the evenings.

    I almost wonder if a barrage of emails to the same company would give them the hint there's a market for this and they should invest some time into it lol.

    ok real question, because I don't want the "maybe" people in this. I want people who want to make this happen.
    No BS, no "I probably would", no "if my brother's friend's friend buys one"

    how many people realistically need a transmission and bellhousing solution for up to 1300HP?
    20 people?
    100 people?

    Sound off, and be ready to back your mouth up with your wallet.
    You want this to take off? Its gonna cost money. A lot of money. I'm betting to get this developed/engineered/molds made/machine work done its gonna cost me $50,000+ to have a very reputable company take care of this. You want a transmission solution? I can make it happen, but its gonna cost bucks.



    What would you pay for a kit:
    Transmission/bellhousing/stall converter/driveshaft/transmission mount/mount assembly.

    Now you will see why this hasn't been done yet. EVERYONE wants it, like 2-5 people would be willing put up any kind of money to make it happen. Its all fun and games until it goes from a forum thread to their wallet...Click here to enlarge

    Is the current transmission being optimized with the existing software? Would a set up like the one you're describing Alex be necessary for where this platform currently is?
    I could be way off but I feel like making a commitment on a set up like that would be difficult when it seems we have other hurdles that need to be crossed first.

    this would be replacing the transmission with a Turbo 400 transmission. They can take incredible abuse and power.

    code car as a manual.
    bolt trans/driveshaft in
    adapt shifter cable to turbo 400 linkage.
    go whoop ass accordingly.

    nope, not a 6 speed.
    nope, no torque converter lock up.

    I mean, unless you can design a 6R80 or 6HP32 with another bellhousing, we have very little alternative.

    TH400 seems like a terrible choice to me, sure they can take abuse all day long and are stout as $#@! I have them in more than one muscle car. For my money I would throw a 4L65E in there and have complete control over it with one of dozens of stand alone controllers, have overdrive, etc. Just a nice modern tranny. The 65E is also smaller than the 8XE's. Just my .02 cents.

    yes, I understand what your saying, but no other tranny has more options for gears/internals/converters than a T400- and they are proven to hold up to 3,000 hp.

    4l60 is another option, and I've tried stuffing one up there. it could work, but to get one built over 1000 hp you are on the edge of their limit.

    How about the DCT? I read on Gintani's instagram they now have full control over the tcu in the DCT, can modify applied clutch pressure, etc. and have upgraded internals, pretty much ready to go... They are are currently swapping the oem smg trans in thier built m6 to a dct. It seems a little to good to be true, but if they have what they posted on instagram, this will be the ultimate solution for e9x m3 owners and n54 guys. There isn't a better trans than the DCT imo, up until now, the fear was whether it could hold a lot of hp/tq.

    This is true, but how many of these guys are going for those power levels? Not many, they want a reliable 600-800 solution a well built FLT stage5-7 4LE65 would hold that forever.

    One of the best options is the TCI 6X. It's a 4l80 slimmed down and rebuilt into a 6 speed. $7k gets you everything including the software to run it. You can even use paddle shifters with it. Would just need to buy a driveshaft and take care of the labor to do the swap but I'm almost positive it would fit.

    Of course also need a bellhousing. Lets face it, a bellhousing would open up the door for plenty of swaps, but swaps are expensive. Maybe the new GM 8L80 will be a great option in a couple years, but that's a couple years away too.

    Most importantly we need a software option. I'm confident with just tuning and a cooler and not touching the trans hardware I bet we can see steady reliable 600wtq handling. I mean how many RB and Vargas Stage 2 guys abuse their trans without issues? And that's 5-550 wtq?

    When was this posted? @Sticky ?

    I'd love to do a DCT swap and call it a day. Only thing is...at what point do you just part out and buy an M3? LOL especially with turbo options coming available.

    They don't offer a bellhousing as of right now, but the 6X trans is good to go, I checked it out about 5-6 months ago. Badass transmission. Just need someone to make some bellhousings. The shop doing my car was going to do it, but they are just swamped right now, and I took my spare trans from them and sent it to nizpro in Australia who is known for ZF6hp26 upgrades, they are confident they'll be sending back a proper transmission build.
