• 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.

        Why is that no one can pick up a phone and call anymore if there is an issue.

        First off, Drew's car has transmission electronic issues. His issue has nothing to do with clutches.

        Second, how is SSP supposed to be able to tell how long the transmission lines are supposed to be when the cooler mounting position keeps getting moved?? We have offered to send the lines and fittings, but never have received anything. I can go on and on...

        Joseph I would recommend closing the communication gap between everyone involved. Alex and I cannot read minds. If you have an issue in the future Joseph, pick up the phone and call. Most people do not read the forums on a daily basis.

        Completely true.

        Alex said he called you earlier. I haven't called as I just don't want to get in the middle of anything and get this wrapped up. Just relayed what I saw.

        Kris, the forum is my business this is where I communicate most often. I'll call you and we will get the lines and fittings resolved. I was not told you offered to send them.

        Probably best for us to just communicate directly, I appreciate the post.

        Gintani needs to re-located the transmission cooler to fit with there kit. This is NOT something that SSP can do. Once they figure out a proper mounting location, they can send us the measurements so we can make new lines.

        Gintani wants money for new lines and whatnot, probably best to just pay and get this done.

        Drew ended up having to buy a brand new transmission due to electrical issues inside of the transmission. The dealer could not even fix the issue without replacing it.

        It was the coding in his tranny itself that was causing an issue so the best bet was to swap for another stock one, the dealer couldnt even code it.

        Damn, a hunk of expensive metal is scrapped now because of some computer coding?

        yeah it sounded like a headache and a half - first they thought it was a sensor, etc... but after all was said and done BMW wasnt even able to code it with the stock clutches in so they had to replace the tranny.
