Transmission 6-speed automatic manual

Traditionally, six-speed manual units have been reserved for high-performance cars. These transmissions feature closer gear ratios than a five-speed manual unit, allowing the driver to stay within the engine's ideal rpm range.

Also, the sixth forward gear allows highway cruising without making the engine work so hard. The Mazda RX-8 is one of many such cars that use a six-speed manual.

In more recent times, even some mainstream cars such as the Ford Fusion have offered to six-speed manual units. These two markets have traditionally loved manual transmissions, for both the smooth-shifting feel and greater fuel economy. Now the system is making a resounding first impression in North America. The PowerShift 6-Speed Automatic Transmission is the result of two parallel manual transmissions working in tandem, combining through a dual-clutch mechanism to create the same effects as an automatic transmission.

In more recent times, 6-speed automatic and sequential- manual transmissions have worked themselves onto passenger cars as well. Six-speed manual transmissions started to emerge in high-performance vehicles in the early s, such as the BMW i and the Ferrari The first 6-speed manual transmission was introduced in the Alfa Romeo 33 Straddle. The three-shaft transmission is also very compact length mm and light dry weight 46 kg and incorporates a number of special features for particularly pleasant gear shifting.

An integrated magnet on the gearshift shaft is detected by a Hall sensor. The signal for reverse gear activates the reversing lights. The large spread of 6. The clutch is operated hydraulically and the gears are actuated via cables. The overhead camshaft with third and fourth gears and the reverse gear do not run in the oil bath. This reduces drag torque, thus facilitating gear shifting at low temperatures in particular. The three-cone synchronization of the first two gears serves the same purpose, while the following gears are provided with two-cone synchronization.

The weight-optimized cast aluminum shift forks are installed on anti-friction bearings on the shift rods, in order to reduce the shift forces. The transmission has six forward gears and one reverse gear. All the gears on the main shaft , except reverse, have synchromesh engagement. Traditionally, six-speed manual units have been reserved for high-performance cars.

Also, the sixth forward gear allows highway cruising without making the engine work so hard.
