2) Model.

4) Engine size.

You haven't given enough detail to go by.

Interesting topic. If this is doable, I'd also like to to convert mine.

@Siena, below are details of my car,

1) Make: Kia
2) Model: Optima
3) Year: 2007
4) Engine size: 2.4ltr

I've decided to sell it cause health reasons associated by terrible Lagos traffic but would be glad to keep it if it can be converted. Is it possible? What parts are required to get this done? Thanks.

With time, money and determination, anything's possible. The question is, do you really think it's worth it? Then you have to question how well it was done.

For the Kia Optima, parts required are:

01) Kia Optima auto transmission.
02) Kia Optima auto driveshafts x 2.
03) Kia Optima auto shift mechanism.
04) Kia Optima auto TCU (Transmission Control Unit).
05) Kia Optima auto ECU (Engine Control Unit).
06) Kia Optima auto wiring harness.
07) Kia Optima auto transmission oil cooler.
08) Kia Optima auto instrument cluster (with auto shift indicator).
09) Kia Optima auto exhaust front section / catalyst.
10) Kia Optima auto starter motor.
11) Kia Optima auto flexi plate (replaces manual flywheel).
12) Kia Optima auto torque converter (replaces manual clutch).

The engine ECU of a manual has no output to communicate with the automatic TCU, which is why I've listed the ECU. Older cars with purely hydro-mechanical automatic transmission are easier to convert, as there are no electronics involved. Don't forget immobiliser issues - if you replace your ECU, you'll need to get it coded to match your ignition, otherwise you'll be pushing that car.

It's a lot to do, just for the "convenience" an auto brings. Not worth the cost if you have to pay a mechanic to do all the work. If you're mechanically inclined, and you have a complete accident damaged Kia Optima auto to raid of parts, then it wouldn't be too bad. Anything less, I'd suggest you sell your car, and buy an automatic.

Good luck.

Even here in the US where there's loads of parts, the best advice is to sell your car and buy an automatic car.

But like said before me, with enough money anything is possible. If you do proceed please take loads of pictures for others after you.
Re: Changing Manual Gear To Auto(need Advice) by Joy2Dwise: 9:29pm On Jan 28, 2012
@Siena. That's a very long list which would come with long headaches.  Not sure I'll be able to cope with it. Doesn't make economic sense either. I'll rather sell it and but auto. Thank you so much for your time.

Oddly enough, I'm doing it the other way round - converting my Audi S8 5-Speed Tiptronic to 6-speed manual. In my case, that's what I do, and selling my car and buying a manual, isn't an option. As it was never available as manual.

Using off the shelf Audi parts (six speed manual is offered on the S8 though nto sure what year they did or what year yours is) or making custom parts?

"European-market models also had a six-speed manual transmission option (parts code: 01E, identification code: DGV)" http://en.wikipedia.org/wiki/Audi_S8

This will be an interesting predicament for me. An A8 is on my short list of cars to own, I woudl love the sportiness of a stick but my big german cars have all been in auto for a relaxed driving experience.

Yes, Euro only. The transmission tunnel has a bulge for the starter motor, which makes it virtually impossible to have a third pedal (clutch) on RHD cars. So that means my pedal box has to be custom made. All my parts are here, just waiting for better weather, when the days will be longer, and I'll be less busy.

If you're after an A8, there was no manual option, even in Europe. So converting it to manual, while not difficult, means you'll have to find a way to trick the ECU into thinking the auto TCU is still there, otherwise it'll throw up a CEL and store error codes. S8 ECU can have the soft-coding value changed (just the last two numbers) so it becomes a manual version.

01E 6-speed was available on Euro Audi S8 D2 from 1995 - 2003.

Because autos are dead boring to drive. An auto is not really classed as a "driver's car", at least not for enthusiasts. Besides auto's are:

01) Slower.
02) More prone to failure (heat build up in traffic being the main killer).
03) Heavier on fuel consumption.
04) Heavier on front suspension components.
05) Heavier on front brake pad and disc wear.
06) More expensive to maintain (periodic service required).
07) Boring to drive - you could fall asleep, as there's very little driver input.

In addition:

a) They offer very little engine braking.
b) Impossible to bump-start the car, in an emergency if your starter motor fails.
c) They place more strain on the engine, when held by the brake pedal whilst in drive in bad traffic conditions.

But for those that like them, it's all good. I'm there to rescue them when they break down, and require a replacement auto tranny, at a price. cool

@ SIENA,

tanx in anticipation of ur response

The 2006 Audi A8 has no manual option. It's based upon the D3 platform. It's also considerably heavier than the D2 models, so may be thirstier and slower. The 2003 marked the change from D2 to D3 platform, though the S8 was not available in the D3 models till 2005/6. So I would presume the 2003 S8 you're looking at is the last of the D2 models.

The D3 has more toys, and air suspension as an option, great whilst working, expensive to fix when it breaks. It also has Audi's Battery Power Management System. So accepting, or giving a jump start can kill the control unit, which means a dead car. Mega expensive to replace.

The S8 is the flagship, and more powerful than the regular A8 model, has better suspension for enthusiastic driving. The S8 is more sought after, and holds its value longer. And of course, the 2003 Audi S8 LHD is available in both 5-speed Tiptronic and 6-Speed manual.

All A8 / S8 feature Audi's innovative ASF (Audi Space Frame) technology. The skeleton is entirely built out of an aluminium space frame. It is incredibly rigid, so the outer panels have no bearing on strength. In short, they don't bear any load. This results in a car that is full-size, but lighter than the BMW 7 series and Mercedes-Benz S-Class, which are conventional steel unibody. Lighter weight means better fuel consumption.

You don't mention what engine size you're interested in with regards to 2006 A8. They are as follows:

Audi A8 D3 2,8 V6 2 x DOHC 30V (210 bhp).
Audi A8 D3 3,0 V6 2 x DOHC 30V (220 bhp).
Audi A8 D3 3,2 V6 2 x DOHC 24V (255 bhp).
Audi A8 D3 3,7 V8 2 x DOHC 30V (280 bhp).
Audi A8 D3 4,2 V8 2 x DOHC 40V (340 bhp).
Audi A8 D3 4,2 V8 2 x DOHC 32V (350 bhp).

And for the 2003 Audi S8:

Audi S8 D2 4,2 V8 2 x DOHC 40V (360 bhp).
