I think we found our transmission for the Sonic Z-spec.....

Okay it may be a little over kill......

The automotive industry has many different types of shows and events, ranging from the local car show, to the massive trade show that is known as SEMA, to the series of auto shows traditionally used only to house the latest products of the automakers themselves.

Not anymore, as ZF has decided to blend the lines of traditional show composition by having its own booth at the Detroit Auto Show in order to unveil its latest transmission – the world’s first nine-speed automatic transmission for vehicles utilizing a transversely mounted engine. In other words, ZF has introduced a transmission to power the increasingly prominent (80 percent of vehicle worldwide) front-wheel drive vehicles that are needed in order to optimize fuel economy in order to meet government mandated standards.

“Already a leader in technically advanced, fuel-saving multi-speed transmissions for rear-drive vehicles, ZF’s new nine-speed enables significant fuel economy improvements and delivers excellent performance characteristics for front-wheel-drive vehicles,” said Hans-Georg Harter, ZF’s President and CEO. In fact, ZF says that the new transmission will deliver an increase in fuel economy of over 10 percent in some applications.

Although the primary benefit of ZF’s new transmission is a dramatic improvement in fuel economy, the transmission producer also produces an increase in performance as well. One way it achieves that is through the use of a new shock absorber system in the torque converter, which makes a rapid lock-up of the converter clutch possible, and also means better fuel economy and lower CO2 emissions.

ZF says that the new nine-speed front-transverse transmission will provide for “extremely short response and shifting times are clearly below the threshold of perception.” This means that double shifts and direct multiple gearshifts are also made possible. Despite making these claims, ZF has been a bit shy about getting into the technical aspects of the new transmission, but expect it to be a dual-clutch setup, and likely dry.

Production will begin in 2012 and will take place at ZF’s South Carolina factory, which will begin construction next month. The first use of this new transmission will be in a Chrysler product – or many – but it is unknown in exactly what.

Did it really mean a dual-clutch setup, and likely dry, with a torque converter? That's the way it reads.

I may be misreading the article...but you reminded me of quirk I noticed when I read it last night....how can a dual clutch-transmission have a torque converter? It seems like the dual-clutch part of things was a guess on the part of the writer.....

It is possible to have a torque conv. on a dual clutch trasmission. The only issue is why would you. Drivability.

Well, sure....but I'm thinking that the operation of the two subsystems are completely counter to each other...not to mention the whole efficiency-goes-out-the-window thing...

Oh there you go getting specific. The dual clutch has two advantages. 1 is a FE enabler by giving automatic "like" performance in a manual which gives you the FE and clutchless driving. But by always having the next up or down gear on the next shaft ready, it has lightning fast up and down shifts. So it is also a performace enhancemet. So if you wanted lightning fast shifts and improved drivability over a manual what might your answer be?

Everything I've seen and read says dual clutch sucks aroud town in stop and go driving. A torque conv. would help that. But as you point out, not as efficietly.

Hmmm....very interesting.

Does this mean GM isn't doing a DCT?

The boys at GMI are going to flip a **** if one doesn't arrive soon.

That would never happen within an online community.

Say what?? I give, what is an FE enabler?

Fuel Economy.

Thanks. I'm having a tough time envisioning the workings yet, but it sounds pretty awesome so far.

Google "Howstuffworks.com DCT"....that site has a pretty easy-to-follow explanation on the concepts behind a dual-clutch transmission.

This new unit from "ZF" apparently uses a torque converter, too.
