    • 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.

        I'm ignorant to what "Stalin's camps" were but will educate myself tonight.

        Perhaps our mothers passed each other in one of those camps years ago. Small world.

        No, my mother wasn't born yet. Her uncle was though and he was one of the few to survive Auschwitz. Unfortunately sent there for being in the Polish military and helping people the Nazis were looking for. But he made it out (lasted 2 years, average lifespan was 2 months in the camp), came here, and opened a Baskin Robbins. Kind of a cool story.

        Joe,

        My rep history is completely irrelevant here so quite trying to change the story (but people are obviously agreeing with what I have to say).

        You were putting every member on this forum with your house comment and only after you read it and the comments did you back track and say you were only putting those down who had put you down.

        As I said, I have no beef with you. You are a young boy and believe you can do no wrong.

        You are also right that this is a build thread but when YOU discuss how much money you have, what a nice place you live in, talk about all the properties you have and put down the car of someone else, do you really expect the thread to stay on topic? You are naive to think you are right in every situation....again, wet behind the ears.

        And for the record, thanks for supporting me and Weistec about the cars.

        It's completely relevant when discussing if you "insult" people. I've seen you do some nasty things, just saying maybe you shouldn't point fingers especially if part of your point is that nobody is perfect which you seem to be implying.

        Back tracking is apparently clarification in your mind.

        Ok and I have no beef with you so then stop taking my thread off course with further OT posts?

        Uh, no. This idiot who built, if you want to call destroying my trans "building" it, accused me of not paying for my motor build so I made sure to make my point with emphasis regarding the monetary level he is discussing here. As if the engine, tuning, body work, wheels, suspension work, exhaust work, brake work, etc., have anything to do with what he was supposed to do which was get the trans right which is why he got it in the first place. Clearly an attempt at shifting the focus and blame so you continuing to indulge the OT aspects only takes the focus off what should be the focus here.

        And that would be @SSPKris completely $#@!ing up my transmission, being over a year late, taking no responsibility, having no accountability, and this not being the first time it has happened. So, while I am fortunate enough to be in a position where this build, trans, and whatever else, has little impact on me financially considering that since it started revenue just from the forum alone has septupled I am all about the principle on this and believe what SSP has done here should be made known so nobody else has to go through it. They are currently looking for some cars, well, the word needs to get out.

        THAT IS THE FOCUS AND WHAT SHOULD BE THE FOCUS.

        If me sharply responding to people putting me, my tuner, and my build down (considering I have made some fairly LARGE sacrifices for the benefit of the BMW modification community) upset anyone my apologies but I'm not some bum begging for change here or someone sugar coating anything to be politically correct.

        Yes, that's exactly what I do and I support all members with whatever they made need whether it be tech support, good deals with vendors, where to buy something, photo coverage, front page coverage, editing, whatever.

        Earl. Get a life dude. Sticky will figure out life without your help. You are obviously jaded on the topic. This whole $#@!storm started because people came in to kick sticky while he was down. So he $#@! slapped them with some insults that obviously struck home. People are so insecure it's hilarious. Then you guys start micro analyzing his life choices. Grow the $#@! up.

        Earl has a nice life no doubt. I'm very happy with my life. This has nothing to do with getting the trans situation resolved.

        Wait, is his life better or worse than the wood side baller!? I need to know who is in first place here! I must know! LOL. Earl should enjoy it then, focus on cars and not on the choices Sticky has made or the way he chooses to handle his life. People have a real convenient memory when it comes to these threads and sticky. Let me educate some of you. Money and material items have nothing to do with true success. But, I've been poor and I've been rich. Rich is a lot better ; )

        I like kittens, but I like DCT transmissions more. Just wanted to throw that out there.

        If there's a real solution to the DCTs, I will most likely trade my car in for a 335IS Click here to enlarge

        I found a 335IS I like. More details on the DCT upgrade please, @Sticky !
