Auto VS Manual

[Scarface.au]

I prefer manual but I own an auto at the moment, it is a lot more satisfying to drive since doing some 'upgrades' to it though. (Corvette servo, UHD bands, steel valve body pistons, pressure increase valve, corvette sun gear, heavy duty sprag clutch, Stage II Transgo shift kit.)

Oh noice, so steps sideways on shifts then?

It does snatch the rear end if you step on it, on the other hand it's quite gentle if you're light on the pedal though; which I'm sure everything behind the transmission would thank me for if it could.

It's a 4L60 by the way, aka: mechanical Turbo 700.

So I was kinda close, mechanical, as in full ratchet shift?

Ah k - so a built commodore box then.. They can be tough! (and if you crack your housing - cheap to shift parts to new box because they're so common). I will be getting an mv-automatics stage 1.5 or 2 shift kit for my A341E soon - will be instant shifts practically

TBH im not for or against either auto or manual - its just whatever I happen to have to drive at the time. Auto are quicker in a straight line, and provided you have everything setup right (cooling mainly), can be quicker around a track. Manual are more fun though imo

Auto will never be faster around a track unless it's DSG.

DSG is a manual box.

Auto can be faster around the track, especially if its built like camstatic's. If you have a fully "manualised" auto - it will be faster.

Yes but they operate automatically in "auto" mode, and technically the driver isn't operating the clutch, it's done automatically by a computer. I see your point though.

I disagree. Unless you can prove me wrong, manual shifts in a trans like that are just to agressive for corners. Plus a majority of them don't even have enough gears.

Not to mention "fully built" trans' are usually in cars that don't handle

There is no way in hell you'll ever see a circuit, drift, enduro, le mans, superbike, v8 supercars, motoGP etc. car/bike with a fully mechanical automatic trans. Because they aren't faster. Except in a straight line.

Not to mention they don't offer enough control, and are quite bulky to operate.

I don't see your point. I reckon they're less "bulky" to operate compared to a manual - its either up a gear or down a gear.

I know of quite a few local guys who drift/grip with 'kitted auto's and some of the cars are built for that purpose. The shifts are rough on full-noise, but if you lift-off a little, they're quicker and a lot smoother. Auto's also have a more progressive throttle response due to the way in which they operate & if used right can be a lot faster than you'd think. They don't have the same feeling of control compared with a manual, yes, but thats why they're not really used in racing. I'm not arguing with you about the fact that that most if not all circuit vehicles are manual - its the more fun option to drive afterall.

Superbikes are a different kettle of fish... lol (wet-clutch...)

Your point about DSG's is interesting though - they are a manual box - but with the computer doing the changes = quicker than a normal manual and less powertrain loss compared to an auto (and very similar shift-times). Thats why you see them on all the latest hypercars etc.

[inz]

I was more pointing out that they aren't auto, not that they're wet slipper clutches.

A mechanical auto isn't as quick as a manual, sure they can be driven fast, but that comes down to the driver, not the trans.

Your friends drift in autos? Lol, apart from the obvious holden/ford jokes, how do they revmatch, or clutch kick... Lol.

Says it all

Who needs to clutch kick when you've got a 1j/2j ? and I'm no holden/ford fan (though my daily is a holden)

I drove a manual for the first 6 years of my driving life.

Now i have an auto. The only reason i do is because it was just too good to refuse!

I do wish i had a manual though. Its a 4x4, and when off roading i prefer the extra control that the manual gives. Auto does the job as well, i just prefer a manual.

Also, the better fuel economy from manuals is a plus

[Hell Boy]

In nearly all situations, manual > auto.

However, if i were to buy a Porsche or a GTR, i think i would go semi auto, purely because it's quicker and the technology is there.

[inz]

Which is DSG and therefore manual.

Success!

[Jeatalong]

The next car I will be getting wil most likely be an auto, it is getting to the stage that auto gearboxes delivery more economy than manuals. Plus most driving you actually do you don't need the extra control that a manual can give you.

[That_Stevens_Guy]

Had a Manual, soon realised that I prefer Automatic with Tiptronic options for my road car. If I was making a track car though, I would probably go a Manual if I can't afford to put in a modern sequential box
