And there is no clutch pedal. What you see looks like a conventional automatic. I own a smart and like the gearbox.

The Elio Automatic Transmission

Jeff--- I understand how the AMT works and your right, there is a lot more to it. The X plane, Y plane shift actuators are probably the simplest part of the whole mechanism. Speed sensors on the gears, even sensors to monitor engagement lug positions on individual gears. A control module decides when to clutch, interrupt fuel flow or blip the throttle to shift up or down. In a conventional automatic the torque converter absorbs a lot of the shock of shifting. Not so with with an AMT so they tend to be a little more clunky in operation. At light throttle the control module sometime seems unsure of just what gear it needs to be in.
apparently EM looked at the one in the Smart Car .... I was told they didn't pick it and the one they are going to use has a much smoother operation

I seem to recall the Smart transmission is a Getrag or ZF. They have a reputation of being clunky. When in automatic mode I think a lot of the roughness can be smoothed out just by learning when it shifts and easing the throttle just as you hit shift RPM. Both the Smart and the Elio having less mass would make the rough shifting feel even more pronounced. Hopefully the Aisin design transmission will be smoother.

. Very well explained. Thanks for posting BIioKart, I think I talked to that guy last week on the Microsoft help desk when I was having trouble on my laptop.

That is not what they have in mind for our vehicle. Ours will be an automated manual rather than an auto stick. No clutch no need to shift. This is not something new http://www.curbsideclassic.com/curb...slers-fluid-drive-returns-in-the-safer-kafer/

I believe the Maruti Suzuki transmission described is very much like the AMT that is expected to be in the Elio.
Earlier this year Jerome Vassallo told us they were looking at using the Aisin manual transmission and either using the same system as the Maruti Suzuki Celario or one that is very similar to it as he told us to look up that vehicle.
There was some conflicting information on the transmission which came out of the Charlotte showing this week and I unfortunately did not get a chance to ask about it so hopefully over the next few weeks some of you all can get us good information directly from Jerome about this.
Excerpts from 3 websites reviewing the mentioned transmission.....
The Alto has always been a fun car to drive and adding the AMT transmission has only made it better.
The USP now is really the automated-manual transmission and Maruti expects a large chunk of sales to be generated by the AMT variant. It certainly is a smart move to take the Celerio's AMT and tune it to match the Alto engine. The gearbox is responsive in city driving and does perform well in traffic. The manual, on the other hand, felt like it could do with slightly more punch in the first gear.
----------------
Getting hold of the AMT automatic version immediately I immersed myself into a traffic jam which would be the natural habitat of the new Alto K10. First impressions are very postive with the smoothened out gear changes feeling much better than the Celerio. It is pretty responsive and jerk free. As you might know it has R, N and D modes with manual mode also there.
At low speeds to move in traffic it is responsive and you if want that instant bit of performance you can use manual mode which gives you control over the gears and allows you to select a lower gear.
------------------
The shift quality isn’t superb or immediate but its comfortable enough without being intrusive. In urban crawl speeds the shift quality is seamless and there really isn’t much to complain about. As speeds increase and you need quicker movement between the gears the shifts are perceptible and with a fraction of a seconds lag.
