Fiat 500 transmissions: 5 or 6 speed, Dualogic or MTA The Fiat 500 comes with a wide range of reliable, robust, sophisticated gearboxes: one is a mechanical unit (with 5 speeds for the 1.2 and 1.3, and with 6 speeds for the 1.4), the other is of the sequential robotized type named the Dualogic. Fiat Dual Clutch Transmission (DCT): C636 The six-speed transmission has a ratio spread of 6; a seventh gear can be added in the future. Fiat’s electro-hydraulically activated transmission eliminates pumping losses associated with wet clutch transmissions. It operates like a manual transmission, with two clutch discs driven independently by a common flywheel assembly.
