Neutral gear sensor
(vehicles with Stop/Start system - from 2010 model year)
| Pos. | Spare part number | Name |
| 1 | - | Neutral gear sensor |
The magnetic inductive PLCD sensor, installed on vehicles with the Stop/Start system, is located outside the gearbox housing and is hardwired to the engine control unit. The sensor is designed to detect when the neutral gear is engaged within a calibrated window. For more information, refer to the chapter: Starting System (303-06C Starting System - 2.2L Duratorq - Td4, Vehicles manufactured from 03/2009 onwards, Description and Function).

The transmission is controlled by two shift cables connected to the selector lever. The movement of the selector lever is transmitted via the cables to two lever assemblies on the top of the transmission. The levers operate the gearshift mechanism to select the desired gear ratio.
The shift mechanism is located at the front of the gearbox and transmits the movement of the shift cable to the shift actuators.
The shift mechanism is a single unit secured to the gearbox housing with four bolts. The shift mechanism moves the upper and lower gear selector forks via transverse and longitudinal levers at the top of the shift mechanism. There are two upper gear selector forks and two lower gear selector forks:
- The two upper gear shift forks are used to engage reverse, 1st and 2nd gears.
- The two lower gear shift forks are used to engage 3rd, 4th, 5th and 6th gears.
Four shift forks transmit the movement from the shift mechanism to the corresponding synchronizer clutch. The shift forks are mounted in bearings in the gearbox housing.
Two carrier plates transmit torque from the longitudinal lever to the sliding shift selectors. The carrier plates are located and operate in a groove on the selector plate.
The carrier plates can move in the vertical plane between 4 positions. The different gears are selected from one of the four positions as follows:
- The top position - the gear selector selects reverse gear
- Second top position - the gear selector selects 1st and 2nd gears
- Second lower position - the gear selector selects 5th and 6th gears
- The lowest position - the gear selector selects 3rd and 4th gears
The gear shift mechanism has two springs that return the selector lever to the neutral position.
Gear selector shafts

The illustration above shows the clutches for each gear group. When these clutches are moved according to the selection of the shift mechanism, the required gears are connected to obtain the required output ratio.
The clutch is part of the synchronizer assembly, which also includes a flange and a hub. Each synchronizer hub is connected to its shaft by means of splines and rotates together with the shaft. Intermediate gears are installed on both sides of each synchronizer hub. The intermediate gears rotate freely on the shaft (except for the reverse gear). Each intermediate gear is in constant engagement with its drive gear. The synchronizer is located between the synchronizer hub and the intermediate gear.
The synchronizers are located on the shafts in the gearbox as follows:
- The synchronizer 1st - 2nd gear is located on the intermediate shaft 1st - 2nd, 5th - 6th gear
- The 3rd - 4th gear synchronizer is located on the 3rd - 4th gear intermediate shaft
- The synchronizer of 5th - 6th gears is located on the primary shaft
- The reverse gear synchronizer is located on the reverse gear shaft
Synchronizer rings expand when heated, as do the elements they are in contact with. As a result, no safety margin is required to counteract expansion. Single and double synchronization intermediate gears do not have cones. This function is performed by the inner synchronizer ring.
