General description of mechanical transmission (Opel Vectra A)

All models are equipped with a 5-speed gearbox. Uses five types of transmission, depending on the engine output and the year of the model. See. Specifications.

2. To determine the final drive ratio, see the transmission number indicated on its end cover. The number also indicates which gears the installed box has (short or long). The manufacturer's codes stamped on the upper cross member of the radiator frame also contain this information (contact your Opel dealer for decoding).

3. The drive is transmitted via the clutch to the input shaft, which is parallel to the output shaft. The gears of the input and output shafts are in constant engagement, and the gear selection is performed by shifting the synchronizer hub to the desired gear of the output shaft. The hub engages with the gear and connects it to the output shaft.

4. The 5th gear components are located under the rear transmission cover at the end of the transmission.

5. Reverse gear is engaged by shifting the intermediate gear into engagement with two straight-toothed gears mounted on the input and output shafts.

6. All forward gears are helical, which reduces noise levels and increases wear resistance.

7. The F18 transmission is equipped with a special mechanism that allows you to engage reverse gear silently.

8. The differential is installed in the main transmission housing. The drive to the differential is transmitted by a satellite at the end of the output shaft. The inner ends of the drive shafts are inserted directly into the differential.

9. The gear selection is carried out by means of the gear shift lever via a special rod.
