I have had manual transmission for awhile but id like to change it on this car i considering buying (please don't criticize, i just want an answer) Could you change it? How? would it still run as smoothly? etc.
The answer yes you could, but the cost would not be worth it. You would need a computer, transmission and wiring harness under the hood. Inside you would have to add a Auto shift console with shifter, and a automatic pedal assembly.
The completed car would run just the same as the factory version if the swap was done correctly.
In the old ,simpler days it would have been easy enough, but today is another matter altogether with all the computer controls. It would be simpler to find another car with the automatic factory installed.
