Triptronic Vs. Auto

[Irugalbandara]

hello all;

Could you please briefly tell us the diffrence between triptronic and Auto Gear versions. how to operate, advantages and reliability etc.

thanks in advance.

A triptronic is more or less an automatic transmission. The mechanically only difference is that it lets you over-ride the "automatic gear shift" and change gears at a point that YOU want. Basically like an auto you put it on "D" and drive it, but you can shift the lever to a mode where up/down movements of the lever triger gear-changes.

I didnt describe the diference between automanual cos i presume you might know that..

As for relaibility, i guess a T/T probably isnt that much lesser reliable than a conventional auto since the operations are nearly identical..

1. Manumatic most often refers to an automatic transmission, with some elements of manual transmission control

2. Different car manufacturers have been using a variety of labels for their manumatic transmissions, such as 'tiptronic', 'Geartronic', 'Touchshift', 'Sporttronic', and others.

3. Like a manumatic, many modern semi-automatic(another type) transmissions can operate in the same manner as a conventional type of automatic transmission

4. Despite superficial similarity, manumatics differ significantly in internal operation and driver's "feel" from semi-automatic transmissions

5. A manumatic, like a standard automatic transmission, uses a torque converter instead of clutch to manage the link between the engine and transmission

6. Tiptronic is a registered trademark, owned by German sports car maker Porsche, who license it for use by other manufacturers, such as Land Rover and the Volkswagen Group (Audi, SEAT, Škoda and Volkswagen).

How 2 Use

In ordinary driving, the Tiptronic transmission functions like an automatic transmission and can shift gears without driver control. When the driver activates the Tiptronic system, the transmission ceases to shift automatically and relies on the driver to change gears. Usually the driver controls the gears with paddle-shifters, which are small levers located on the steering wheel. One paddle shifts gear up to a higher gear, while the other shifts to a lower gear.

This is actually new to me.....May i ask how its different from the traditional T/T, and torque converter?

Btw, the T/T lever doesnt always have to be on the steering. i've sene pleanty of vehicles where T/T is activated simply by pushing the gere lever away from the driver and then shifted using a up/down motion..

Basically a Manumatic (triptronic) is a traditional Automatic Transmission with manual input capability. They both work the same way (torque converters, etc) but the only difference of the Manumatic being the capability to shift gears when the driver wants to (if switched to this mode). The gear shift levers can be on the steering or on the centre console.

Then you have a traditional Manual transmission and the Semi-Automatic transmission. These two are mechanically similar (clutch, traditional gearbox) but the difference with the Semi-Auto is that it has no clutch pedal and all you get inside the car is a Auto transmission like control. The clutch is controlled by a computer and mechanical actuator unit. So when the computer tells it to change gear the actuator operates the clutch and changes the gear. This variant can also have a Triptronic like manual input capability where the driver is permitted to change gears. All this does is do the clutch pedal work and changing of the gears using electronic actuators and a computer.

Hope this helps.

thanks you all for taking time to reply and clarifying the different features of gear system. I am enlightened. thanks.

I guess this may vary by manufacturer/model, but the ones I've seen don't actually rely on the driver to change gears, but rather give the driver the opportunity to change gears.

The difference being that, if you are on a manual and you slow down too much without downshifting, the engine will stall. On a tiptronic, it will downshift if there's a risk of stalling.

Similarly, on a manual you could run the engine at very high rpms but the tiptronic would shift up if the rpm went beyond the "safe" range.

As for advantages of tiptronic over regular auto; with auto, the gear changes are at predetermined speed (some balance between fuel economy and performance). with the tiptronic, you get the benefit of manual (able to change gears to improve fuel efficiency or improve performance, depending on what the need of the moment is) without the hassle of having to be in manual mode all the time.

basically you get the (more or less) best of both worlds

Does driving around in manual mode on a tiptronic really increase fuel economy? Cause on an tiptronic the gear changes at set speeds regardless of whether you running auto mode or tiptronic, so the fuel consumption would remain the same, wouldn't it?

Lately i bought Toyota corolla Axio.. it has Automatic gear shifting..does any body knows what are the B and S positions are????

Im little bit confusing about these positions..plz help me..thanks..

In triptronic mode the gears will only change at a very high RPM to stop damage to the engine or very low RPM to stop the engine stalling. These change points are not the same as they are when its in auto mode. so in triptronic you get the chance to change early.

Well, if the changes did happen at the same set speeds that would defeat the point of putting in the extra bits to call it a tiptronic

plus, some have a "sports" mode that adjusts the gear change speeds for more performance (basically, delays changes so you get more performance, at the expense of fuel economy, engine noise, engine wear and comfort)

Have also seen this on a Corona Premio. That "S" would be the sports mode (as above), and "B" is for driving in hilly conditions and will employ engine breaking to reduce wear on brake pads.

Edit: PS. If you have an overdrive button, then you can turn overdrive off when going uphill/downhill. You get better pickup going up and engine braking going down

What I mean is; to achieve better fuel economy, you have to keep the revs down. So, in order to achieve that, I pretty much have to shift up at the same point as the tranny would do in auto mode cause it doesn't let you shift earlier. Which would mean driving in manual mode on an auto box seems kinds redundant, in the context of fuel consumption, right?

It would let you shift earlier, just not so early that it would cause the engine to stall. But shifting so early may not necessarily be the best for economy (I don't know for sure, but I guess it depends on torque/power curves and how quickly you are trying to accelerate and so on)

AFAIK the ideal thing for fuel economy would be to keep the engine running at the optimum RPM, which is the claim to fame of a CVT (there are some cars with CVT Tiptronic - e.g. Honda FIT Aria)

That's a good point, as opposed to talk about trying to keep the revs as low as possible. Although almost all these websites advise keeping the revs low. Will do some more reading... thanks mate.
