    • 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.

        does ssp do the tranny software as well or just build?

        You were going to Gintani last week Sticky.
        What happened there, and what has been done to the car in the last week?
        When will it be ready?

        You assume? O man, this is not gonna end any time soon, now is it...
        Tell me, do the Gintani people at least have all the parts in stock to at least finish this part of your build without more delays?

        Here is a shipping number for the trans oil cooler fans which have been shipped to Gintani by SSP: http://www.stamps.com/shipstatus/sub...00940660776673

        Once they get the fans, they will relocate the trans cooler and run the lines and such all themselves. Once that is done we should see the motor in and the SC installed and tuning taking place. It is not out of line to think this will be done next month.

        NOW STFU.

        See Sticky, the way $#@! gets done is like this.

        Step 1) Dial SSP's phone number

        Step 2) Ask for a $#@!ing tracking number for the shipment so you don't have to wait until the end of the business day Monday to find out that the $#@! really did'nt ship out. (anyone want to take bets on this)

        Squeeky wheel my friend, squeeky wheel...You're too passive, you're getting owned by these tuners. Let them know you mean business and they will make $#@! happen, if $#@! doesnt happen smear their $#@!ing names like soft butter on toast.

        Don't want to piss Sticky off, though he couldn't do much about the delay without joining a fight, he could manage things better. Buy sending the trans to SSP and sending the car to Gintani and getting these builds occurred at the same time.
