GENERAL INFORMATION

Noise at car movement with the lever of gear shifting established in neutral situation

• Wear of bearings of an entrance shaft of a transmission (noise vanishes by pressing of a pedal of coupling).
• Wear of the vyzhimny bearing (noise appears by pressing a pedal of coupling and vanishes at an otpuskaniye of a pedal of coupling).

Noise when switching one of transfers

• The synchronizer of the corresponding transfer is worn-out.

The complicated gear shifting

• Coupling is faulty.
• Wear or damage of drafts of gear shifting.
• Draft of gear shifting is incorrectly adjusted.
• Wear of the synchronizer.

The lever of gear shifting is not fixed in demanded situation

• Wear or damage of draft of gear shifting.
• Forks of a choice of transfers are worn-out.
• Draft of gear shifting is incorrectly adjusted.
• Wear of the synchronizer.

Transmission vibration

• Low level of oil in a transmission.
• Bearings of shaft of a transmission are worn-out.

Leakages of oil from a transmission

• The sealing ring of a target shaft of a transmission proceeds.
• Connection of a case of a transmission proceeds.
• The sealing ring of an entrance shaft proceeds.
