* 6-speed manual transmission: This was the standard transmission offered.
* Tiptronic S 5-speed automatic transmission: This was an optional transmission, offering a more comfortable driving experience.
It's important to note that some models may also have had the option of a 6-speed Tiptronic S automatic transmission for the later years of the 997 generation (2006-2012).
To be absolutely sure which transmission your specific 2006 Porsche 911 has, you should check the vehicle's documentation or contact a Porsche dealership with your VIN number.
