Removal and installation of transmission Nissan Almera Classic

The main malfunctions, for which it is necessary to remove the gearbox from the car, are eliminated:
- increased (compared to usual) noise;
- spontaneous disengagement or fuzzy engagement of gears;
- oil leakage through seals and gaskets.
In addition, the gearbox is removed before the clutch, flywheel and rear oil seal of the engine crankshaft are replaced.

USEFUL ADVICE: The work of removing and installing the gearbox is very laborious, so be sure to first make sure that its malfunctions are not caused by other reasons (insufficient oil level, defects in the clutch release drive, loosening of the gearbox, etc.).
The gearbox is quite heavy and its shape is awkward to hold, so we recommend removing it with an assistant.
