The Focus comes standard with a five-speed manual transmission. Depending on the engine, the iB5 manual transmission (1.4-1.8 l), the MTX-75 transmission (2.0 l Zetec-E; 1.8 l Endura-Turbodiesel) or, only in combination with the Zetec-SE 1.6 l, the 4F27E automatic transmission. All forward gears in the iB5 gearbox are fully synchronized, the first two gears even with double synchronization. All "moving" gear pinions rotate in plain bearings. In the MTX-75 gearbox, the gears rotate on needle bearings. In addition, the reverse gear is also synchronized, gears 1 to 3 have double synchronization. It consists of an internal synchronizer locking ring, a conical ring, an external synchronizer locking ring and a synchronous body. The gear pinion does not have a conical surface: synchronization is carried out by means of the synchronizer locking rings and the conical ring, which is connected with a geometric lock to the gear pinion.
Dual Sync: 1 - transmission gear; 2 - internal synchronizer locking ring; 3 - conical ring; 4 - external locking ring of the synchronizer; 5 - synchronous body.
Diverse: Ford also puts different versions of the iB5 gearbox in the Ka and Fiesta models. The main difference from the Focus is in the gearshift mechanism: instead of a shift lever mechanism, the Focus has gears that are connected to each other by cables. 1 - Clutch master cylinder; 2 - gearbox ventilation; 3 - input shaft; 4 - output shaft; 5 - differential.
