The

Duo Select
The
Duo Select transmission was available at the launch of the fifth generation Quattroporte, in 2004. Duo Select was an advancement of the
Camcorder unit first used in the Maserati Coupe. It is a Ferrari based semi-automatic transmission, located at the rear of the car, with the clutch located in a bell housing attached to the rear of the engine.
Automatic
Because of reliability problems and rough shifting with the Ferrari based semi-automatic transmission,
a full automatic transmission with 6 speeds was presented at the Detroit Motor Show in January 2007 with the first cars delivered right after the launch, marketed as the
Maserati Quattroporte Automatic.
The Automatic was made available with paddle-shifters on the Sport GT model as standard, but on the base model and the Executive trim levels paddles became an optional extra. With the Automatic, Maserati completely redesigned the under pinning of the car to fit the new conventional automatic transmission and torque converter right behind the engine. They also converted to a wet sump oiling system for cost saving purpose.
