* A 6-speed manual transmission: This was a standard offering on many models.
* A 4-speed automatic transmission: This was also available, particularly on some lower trim levels.
* A 5-speed automatic transmission: This option may have been available depending on the engine and trim level, though less common than the 4-speed automatic.
To know for sure what transmission a specific 2011 Jeep Wrangler has, you'd need to check the vehicle's documentation (like the owner's manual or the sticker on the driver's side doorjamb).
