* 6-speed manual (NSG370): Available on some models, mostly with the V8 engine.
To know for sure what transmission is in a *specific* 2006 Dodge Ram, you need to check either:
* The vehicle's documentation: The owner's manual will list the transmission type.
* The VIN (Vehicle Identification Number): A dealer or online VIN decoder can use this to determine the specific options and components of the truck.
* The transmission itself: Look for markings on the transmission casing, but this requires some familiarity with automotive parts.
