Manual Transmission Specifications (Hyundai Getz 1)

The identification number of the gearbox H51973 337661 is deciphered as follows:

• H - type (H: M5AF3);
• 5 — year of release (2005);
• 1973 - Final Drive Ratio Code (1973: Ratio 3.842; 2073: gear ratio 3.650;
• 337661 - serial number (000001-999999).

The gearboxes of the 1.3 l and 1.6 l engines differ in the final drive ratios.

The gearbox converts the torque transmitted from the engine in magnitude and direction. This is necessary to ensure optimal speed and cross-country ability of the car, as well as for the most economical operation of the engine and the movement of the car in reverse. In addition, the gearbox disconnects the engine and transmission when the car is stopped and parked and when it is moving by inertia with the engine running.



The gearbox components are housed in a crankcase which is bolted to the rear of the engine.

The torque from the engine is transmitted to the input shaft of the gearbox via the clutch. The output shaft of the gearbox transmits torque through the differential to the drive shafts. The gear is engaged by moving the sliding clutch of the synchronizer, as a result of which the gear is rigidly connected to the shaft of the gearbox.

The gearbox is a very complex unit and its repair must be carried out in a specialized workshop, therefore this chapter only covers the removal and installation of the gearbox.

To remove the gearbox, you need to lift the car and secure it in this position. You also need to use a stationary jack.







The gear ratios of the gearbox, aggregated with different engines, are given in the table.
