Thanks! Corrected this soon after you posted.

Well, the Alto
will be getting an AMT by the end of 2014. After that happens, it should be fairly easy to bolt on. The trickier issue will be the controls in the cabin (but they are just electronics, so it is possible).
Alternatively, you could retrofit a half-way-there solution like
this.
Or opt for a eClutch system from

In most cases (baring close to WOT and heavy loads) the upshift points would be similar to those mentioned in the review. What other info would you have liked to see?

For smoothness, definitely the latter! Mostly because the gearshifts happen when you expect (or rather dictate) them in that case.

Let me just clarify here (as well as edit the opening post to avoid any confusion): this does NOT mean the car shifts to neutral when you take your foot off the accelerator whilst going uphill. This also does NOT mean the car does not downshift - it only applies when
lugging at crawling speeds (in 1st gear). The fact is that you'd have to be a horrible driver doing something terribly wrong to ever get into this situation. To put it into perspective, if you did the same thing in a manual car, the car would stall. In this case the AMT shifts to neutral to prevent a stall. It was just mentioned as an interesting / technical observation.
That said, it would probably be safer to stall in-place than to shift to neutral - however, the AMT is using the same logic it does when say, you try and drive ahead when there's a big rock in front of your wheel.

Yes, it is. To add to what was mentioned earlier, we only ended up driving the car in April - and the next few weeks were spent dealing with Team-BHP's server move, which to be honest affects TBHP in a much larger way, and hence i had to prioritize that over the Celerio review.

Source. Naturally they are a generalized value for each type.

Since we were talking about the transmission in that post i provided energy efficiency numbers for better understanding of each type of transmission. For comparing overall fuel efficiency, there's already the ARAI numbers which consumers are well familiar with.

That's strange, and sounds like more of an electrical problem to me, simply because the act of shifting from D to M does absolutely nothing mechanically.
