Re: GM/collaboration 9-speed transmission...At LAST

^ maybe use a germanic name for it instead of PowerShift or DCT?
...and illustrate the side-by-side gear sets (afaik) with a couple knockwursts?

Richard Truett - May 23, 2016

...GM spokesman Tom Read tells Automotive News that vehicles equipped with the stop-start system will use absorbent glass mat batteries (AGM) and tandem solenoid starters to enable faster and smoother restarts...

..."Everyone will end up adding start-stop," says AutoPacific analyst Dave Sullivan. "Now there's a benefit in the EPA cycle, which there wasn't a few years ago. GM's new nine- and 10-speed automatic transmissions have been engineered from the beginning to incorporate start-stop. That will make it much easier and much smoother. That's what's been the holdup. First it was a regulatory issue, then it was a hardware issue."

The new transmissions, developed jointly with Ford, have accumulators that keep the transmission pressurized when the engine is off. That enables the vehicle to move away quickly the instant the engine is restarted...

I dont know, right now Ford and DCT and a couple words that shouldnt be used together, the Powershift has left a bitter taste in many peoples mouths. I know mine has pushed me nearly to the point a swore I'd never buy another Ford again. That didnt last

I have a feeling there will be several 'flavors' of the 9-speed transmission. I remember a comment about the 9-speed from someone at Ford calling it the 9-speed transmission 'family'.

For small cars, more gears offers the lower revolutions and better fuel economy, without having to go CVT like Honda and Toyota with simulated gear changes. Ford being more driver focused, like BMW, I expect a compact/sub-compact version, especially for the new Focus, C-Max and Fiesta.

I think the launch of the 10-speed with F-150/Raptor and possible 9-speed with Fusion Sport/MKZ 3.0t/Continental 3.0t is due to higher engine/trim costs that can absorb much of the transmission premium to increase the take rate. Which should drive the price down a bit so it's more viable for lower trim level models in the next year.

Yes, I also foresee a continued of mating the 6-speed to the base and small EB engines in these cars. However, the ST and RS model, hmmmmm.

"Technology Preview: We Drive Honda's 10-Speed Automatic Transmission
Motorathority

Nov 11, 2015
It wasn't too long ago that a six-speed automatic transmission was state of the art. Then we got seven-speed, eight-speed, and nine-speed units. One of the nine-speeds, designed by noted transmission manufacturer ZF, has given multi-speed transmissions a bad reputation. Paired with four-cylinder and V-6 transverse-mounted engines in Fiat Chrysler Automobiles [NYSE:FCAU], Jaguar Land Rover, and Honda/Acura vehicles, it dithers instead of downshifting, sometimes clunks into gears, and barely ever reaches the top gear.

Given those shortcomings, it may not be wise for any automaker to build a transmission with more gears. And yet Ford Motor Company [NYSE:F] and General Motors Company [NYSE:GM] are teaming up to build a 10-speed, and Honda is developing one of its own. The plan is to use the 10-speed with the V-6 engines in large Honda and Acura vehicles, possibly in 2018 models. Honda says it will improve fuel economy by 6.0 percent over the current six-speed.

Prior to the Tokyo Motor Show in late October, I got the chance to sample Honda's forthcoming 10-speed at the company's R&D Center in Tochigi, Japan.

The car I drove was an Acura RLX, which was paired with a 310-horsepower 3.5-liter V-6 and a development version of the 10-speed. The test drive consisted of two laps around the facility's high-speed oval, which means I spent just a few minutes in the car. However, I was able to assess how this transmission acts in its current stage of development.

Both when accelerating from a stop and when fluctuating speeds, the transmission executed smooth shifts without delay. There was none of the shift shock that you get with the ZF nine-speed. I also eased along at about 70 mph to see if it would be able to get into 10th gear. That happened without a problem, and it was quite a weird sight to see 10th gear indicated in the instrument cluster between the speedometer and tachometer.

The oval permitted speeds up to 111 mph, and while I got up to that speed, I also slowed down to 70 then punched it to see how the transmission would react in a simulated passing procedure. Honda says the transmission can downshift up to four gears at a time, but during this test the transmission downshifted from 10th all the way to 4th. It probably occurred in two steps: 10th to 6th, then 6th to 4th, but it happened quickly enough that any driver would be happy with that performance on the highway.

My time with the 10-speed was too limited to render a verdict, and low-speed city driving would expose any problems it might have with indecision. However, based on this short drive, this transmission looks like a winner."

Re: GM/collaboration 9-speed transmission...At LAST

In a statement Wednesday to Automotive News, GM provided more information about how it says the error occurred. The ’16 models were equipped with new “emissions-related hardware,” which required new emissions tests for those vehicles, GM said.

“The fuel economy data from these tests were not captured in calculations made for EPA fuel economy labels ... causing 2016 model year fuel economy numbers to be overstated,” it said.


It seems trying to push actual 2017 model vehicles in under 2016 rules didn't work out. The new 'emissions-related hardware' was specifically for 2017 model year vehicles, and was required for the vehicles because they were launched well into the EPA's 2017 production model year.

GM and their double-speak continues, just like trying not to call the Volt a plug-in hybrid, which it is.

I like that speculation. This might be available when I'm back in the MKZ market early next year

Re: GM/collaboration 9-speed transmission...At LAST

The F-150 launch on the Raptor and 3.5L EcoBoost does make it seem that Ford is launching on 'upgrade' engines, my guess is to minimize the price premium for the new transmission. Understanding that the cost of the premium engine must be going down, while the new transmission brings the combo back up. The 3.5L upgrade is already about $2,500 at lower trim levels for the F-150, so expect to increase the take rate, Ford will keep the upgrade about the same. Seeing that Ford needs the mpg increase for the high volume F-150 models for overall CAFE numbers as much as the consumer does personally.
