• 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.

        Regardless, this will be solved most likely with a stock trans. I don't know what I will do with the one SSP $#@!ed up.
        I can't find the part number, but I remember reading somewhere that it's about ~$3k

        I don't get why SSP shouldn't be buying me a new trans and they can take this one back.

        I took one class in law school, and now I send all my tax/audit cases to Texas Tax Group. Much easier that way :p

        If you want to practice tax law, you don't need a LLM. LLMs are usually for people that want to teach.

        Based on what you've stated so far, I'm thinking a DTPA demand letter would get you started in the right direction. DTPA is a cool cause of action because it gives you a chance at getting triple damages and attorney's fees.

        I can help you draft a letter free of charge, but you would need to send it yourself.

        If you want the whole package I'd have to get my boss involved, which won't be cheap and you may be better off just using any potential attorney's fees for a used transmission...
