    • DCT Build Part XII - Build complete, pictures of final assembly, transmission cooler, and Viton seals

      Well, this has been a rather lengthy road to completion but the transmission is basically complete. The car was dropped off by SSP last month to Gintani who should have the motor in by the end of this week. The problem is SSP mounted their trans cooler in the location the heat exchanger for the supercharger needs to go so SSP will need to come to Gintani's facility to re-run their lines as the cooler will need to go in a different location. What took so long for this update? Well, we have been waiting, and waiting, and waiting for SSP to send us details on the Viton seals that required 3 redesigns but never received the information on why these seals are superior to the stock units.

      So, I decided to do my own research and here is what I came up with. These are the stock BMW seals used in the DCT. What is wrong with them exactly? We do not know other than they apparently are not up to the task:










      Here are the Viton seals which delayed the project by 3 months. Viton is a synthetic rubber used for seals, O-rings, things of that sort. Viton was likely used as it is less susceptible to decay and already used in BMW applications such as in VANOS. Viton has much higher temperature and chemical resistance characteristics than the stock seals. Here is what they look like:










      This is the DCT cooler that was mounted by SSP up front. This needs to be moved somewhere else as the supercharger heat exchanger will need to go there. This means SSP will need to come out and run their lines again checking all their fluids and so forth before tuning can take place:














      This is the final assembly. So, the transmission is built but it took about a year longer than estimated. I believe I was as patient as possible and hopefully this will all be wrapped up in December with a built motor, built transmission, a YSI, and a ton of horsepower.

        Ok, so it looks like SSP is just going to walk Gintani through the last stages of the transmission. They will need to fit fans and relocated the cooler. It looks like they will be putting it on the back of the car since there is no room up front.

        I told them I want it done by February 25 so I can attend the roll on racing event. Will it get done by then? I honestly doubt it but I will remain optimistic.

        I really hope it doesn't take them a month and a half to complete those tasks.

        They also still have to install the SC and tune it. I also don't even think my motor is in there yet as sad as that sounds.

        Well my father always told me that with patience comes great things. It is has always proven true for me. At least you know it'll be a bad mother $#@!er when you get it back.

        Yep, the only question is "when" do I get it back...

        Didn't I see a clip here where HPF pulled a motor from a M3, screwed a SC on completely, got the engine back in the car and tuned it in 2,5 hours?
        Why does it take those screw ups at Gintani months to do this?
        It does not make sense to me. They are screwing you over.
        This is not rocket science. It is mounting a cooler and a SC for crying out loud.
        They must have done this numerous times.

        Are you offering them free advertising for the time of the build?
        What do they gain by still having your car there?

        I completely agree. It doesnt take a few days for the engine to be built if you have all the parts ready and if the bracket for the SC etc everything is ready then whats the reason for the dealy. You already have the trans cooler issue started. Even the delay from the trans cooler positioning shouldnt have stopped them from at least installing the engine back.

        They aren't screw ups, the work is actually really high quality. Kris@SSP commented on how the quality of the welding was superb for example.

        And yes, HPF did get a car done that fast but there were also a few mistakes there due to rushing it.

        No, no free advertising.

        Yes, they are extremely busy at the moment.

        Still the question remains what Gintani gains by having your car there for such a long period of time.
        Clearly your car should be their top priority by now. Even high quality work does not take this long to finish.
        And I can not imagine that there are cars there that have waited longer to finish then yours.
        Or they must have a really big parking lot...

        If only the system first come first serve applies there you should be driving your car next week.
        I'd be showing up at Gintani daily by now if I were you. But that's just me.

        I think agree with you. I wouldnt be a happy camper if the car was so late.

        There isn't much I can really do except bug them. I'm taking care of it, it will get done. Just patience... Seems like you guys need it more than I do!

        Bug them. Bug them? They need a firm kick in the balls, that's what they need!
        Bug them...

        No seriously. Go there, offer them to order parts yourself if they are too "busy" to take care of it. Take $#@!ing charge of your build if they won't!
        It has past the time of wanting this build to finish. Probably more then a year, but that was the tranny's fault. Ok, granted.
        But Gintani has full control of the build now, so no more excuses. Make them work on it. They need to step up some notches.
        This is no quality shop. It looks like a bunch of slackers to me.
        I would only bring my car there for a tune if I plan to leave the country for a year...
