Agreed...the transmission is the weakest link in the the current Smart drive-train...can't wait to experience the redesigned 453 model...RIP to the current tranny!

It's funny how many forum members like to defend the driveabilty of the current transmission...the simple fact is...there has never been a single automotive publication that has provided a positive review of the current Smart transmission...not one! :rolleyes:
Yeah that...not one !!:wink:

If you like the tranny, good. If you don't, deal with it or sell the car. I mean really, what is the point of making post after post complaining about it? It's not going to make a difference. :) :D

Mercedes is done with the 451. They've already confirmed that the new cars will have the option between a DCT or a standard Manual...They've listened to those poor reviews, they got rid of the transmission, everyone wins...

It'll be like me chastising Apple for the rear glass of the iPhone 4S, when the iPhone 4S is already being replaced by something with less glass and more aluminum (iPhone 5).

This review doesn't praise the transmission, but rather gives it a fair shot:
2008 smart fortwo |*MotorWeek

This one, also gives it a fair shot:
smart fortwo review.

This one, actually praises it: :)
2013 smart fortwo review

Oh, and we're also the only city car to earn a JD Power award, not the iQ, not the Spark, not the 500. :cool:

smart fortwo - J.D. Power

So there you have it, at least one positive review, now stop complaining and get out and drive! :) :D

Outside of the US, 98% of the cars are manual. The Getrag gearbox may feel slow and jerky but it's no slower than a manual change and more consistent too.

Proper auto boxes sap power and increase fuel usage.

Not to mention that the smart gearbox makes you a better driver as you look further ahead and read the road so you are in the correct gear for when you need it.

I could give a rats foot about what a poorly guided or misinformed opinion has to say about the smart transmission. If they knew what they were talking about there would be some credibility, but when their facts are wrong then poor opinions are useless.

Auto transmissions are becoming much more sophisticated every day compared to the ones most of us grew up with. Obviously the smart doesn't use one, but some newer cars with current auto transmissions do get better performance, and in some cases, better fuel mileage than their manual counterparts - and more will be coming along, in large part due to computer controls and higher EPA mileage requirements in the US. :)

Yes, but as they grow more complex they are also increasingly complicated to repair and rebuild.

And they'll always be larger and heavier than their manual counterparts. So these auto's still have a long way to go if they're going to displace manuals and self-shifting manuals in economy vehicles, and performance cars.

We can also technically improve the mpg's of a manual trans by adding 6 and 7 speeds to them...

And some automakers do just that. The only reason why the automatic has caught up is because many manufacturers have just given up on improving their formula for a good manual transmission. Sad, really.

And don't even ask about the CVT, if yours gets a problem you'll be better off just trashing it and buying another.

which is more difficult? teaching writers to drive or teaching drivers to write? the two skills sets don't have a lot of overlap. with everyone and their dog becoming a writer on the internet it's difficult enough to find a professional writer that is paid for anything more than causing enough controversy to get more comments than the scribe next door. and everyone knows, even computers can drive a car...

what I don't get is why someone's opinion (who doesn't know how to shift a smart transmission correctly) is somehow more valid than someone else's opinion (who knows how to shift a smart transmission correctly).

Oh, not always. I thought the issue was they weren't as efficient and robbed power from the car.... now we want to talk about more complex and complicated to repair - can't be any worse than our little $15K cars which can cost half that to replace a failed engine.

Anyway, back to the topic - great article today about the new GM 8 speed auto going in the 2015 Z06 (heresy in itself, putting an auto in a Z06) - developed and produced at GM's transmission plant in Toledo. The engineers were told the new transmission could weigh no more than the six speed auto it replaces; it doesn't - it weighs 8 pounds less, and will handle the ~625 hp from the new Z06 powerplant, which the older GM 6 speed auto would not. Auto engineering is rapidly evolving and a lot of the old "truisms" just don't hold up anymore - 3K mile oil changes, anyone? :wink:

But that's in an expensive Corvette, a heavy Corvette, not in an economy car. Notice they also offer a 7-speed manual transmission too. In the current Corvette (not a Z06) it gets up to *29* highway MPG's. *29* in a Corvette!

That's because they went out and offered a 7-speed manual, not too many cars do that. But if the engineering focus was just as intent on advancing the manuals as they were the automatics, they would still weigh less, they would still be the easier repair, the more durable choice, and the smaller transmissions.

But you also mentioned performance cars - doesn't the Z06 count...
Let's wait until the EPA numbers are in for the Z06 automatic - I think you'll be surprised. We're comparing apples and oranges here in the Vette and the smart, don't you think?

As far as offering traditional manual transmissions, yes manufacturers (some) continue to do that in their cars (some) but the number that matters is the percentage sold with manual transmissions. Right now, ~7% of sales in the US. Not really worth putting huge amounts of money and engineering resources into the traditional manual transmission for most manufacturers, unless in a halo car like the Corvette. Even Porsche seems to feel the manual is on its way out: http://www.smartcarofamerica.com/forums/f7/swan-song-manual-transmissions-62793/

I certainly enjoy the manual transmissions in our Corvette and Mini - but the next Vette we get will have that new GM 8 speed auto in it. :)

Whatever the industry decides, based on profits or fuel economy, that's fine. As long as we are willing to still be fair and honest in our assessments of the benefits and drawbacks of both technologies.

So far, some auto transmissions are obtaining greater fuel economy. Most of that is due to more gears especially multiple overdrive gears up high. And they are all more user-friendly than manuals and auto-manuals. Just about everything else in terms of durability, weight, size, maintenance requirements, its ability to be repaired/maintained, cost (per unit basis), performance, and longevity are all advantage manual transmissions (and true auto-manuals).

Which is why they are in 7% of cars sold in the US....:wink:

I can remember the Sony Betamax supporters declaring it was the superior format right up to the point it disappeared. It was, technically, but consumers preferred VHS.

That's okay, an auto is "better" in terms of user-friendliness. I don't deny that by any means. :wink:

jwight is correct... the availability of manual transmission's is winding down...and additionally...debating the functionally of the current 451 transmission is probably a mute point since the Smart 451 is on it's final year of production...and soon to be discontinued!
