cool link about 6 speed from x3's/3 series - impressive stats, maybe with some srt tuning this could be the new trans haha

OH YESS! Very nice, love the PDK's and anything dual clutch is certainly going to be better as long as its executed propel. I mean just the idea of being able to have a separate clutch is appealing as far as time and power delay goes I really like the older SMGs in the BMW and have only heard good things about the new DCT they have. The 135i shifted awesome when I test drove it, very fast and put me back into my seat through third gear easily!

*cool link below on trans used in some x3/3 series. Maybe with some srt tuning it would make a nice 6 speed auto for the SRT? Has some nice #s to support

Realistically the cost associated with that kind of trans technology isn't something I can see being thrown into the Jeep just due to the market and their target MSRP's but I really cant say it wont happen either. Maybe the '13 will get a new ZF 7DT like that of the PDK in the Porsches. To me any new dual clutch trans with a rev matching feature programmed into the sports system is a win

Im all for any performance improvement of that stature if they keep the sticker under $50k! . . . give or take a few thousand I guess

Re: SRT8 W5A580 Trans Question

Well just to note, it has been confirmed in car and driver article it doesn't rev match as expected

But as far as I understand, at least w/ the nag trans in the srt8 for now, there is no way to have it really revmatch without changing all tcm/pcm tuning and some other things Only because in an auto the transmission is never really disengaged from the motor and during a downshift in an auto the tcm would have to somehow signal the valvebody and stop the hydraulic operation for a brief moment so that the converter fluid pumped into the VB doesn't signal the system to change gears immediately. THEN the pcm would have to signal the throttle control module to blip the throttle to increase the revs the calculated difference for that gear and THEN the hydraulic operation would have to reengage the next lower planetary set immediately. With this all said, I dont know how feasible it would be to make this all happen and the costs of it. So is it possible? YES. Is it likely to happen ever for the WA580, NO.

Maybe w/ the new 8-speed (if they can make it work w/ the 6.4) itll be incorporated, I mean enough demand and enough hype building to get the word to them, and maybe they will make it happen.

I think they have bigger issues though w/ this high (for a Jeep) price-tag. In my mind its still a deal as they given us A LOT more for our $ with this new one it seems. Sure its a Jeep but were trying to move up in th car world and price will and has to reflect that if you want true quality materials. Im not against it, Id love to see Jeep climb up to the BMW/Range with one of their models.
