* 6-speed manual transmission: This was the standard transmission for all 911 models in 2005.
* 5-speed Tiptronic S automatic transmission: This was an optional transmission available for most 911 models. It featured a "Tiptronic" function that allowed the driver to manually shift gears using paddle shifters or the gear selector.
Keep in mind that there may have been some variations in transmission options depending on the specific model year, trim level, and region. If you're looking for information about a specific 2005 Porsche 911, I recommend consulting the owner's manual or a trusted online resource like a car information website.
