11.7. Diagnostics of malfunctions of knots of transmission

GENERAL INFORMATION

Transmission noise

• Noise of chain transfer – the howling or roaring noise, which level increases or decreases at change of frequency of rotation of country houses of the engine. Noise is absent at car dispersal with a small corner of opening of DZ and in engine operating time on a place at inclusion in a transmission of ranges D (Movement) or R (Backing).

• Noise of the main transfer – a rumble, which level depends on speed of movement of the car. The rumble is especially appreciable at car dispersal with small extent of opening of DZ and during movement nakaty with the released pedal of an accelerator.

• Noise of planetary transfer – howling noise which is most strongly shown on the 1st transfer and transfer of a backing and depends on speed of the car. Noise of planetary transfer can decrease or vanish when switching transmission on an adjacent highest step.

• Pump noise – the howling sound of a high-pitch tone increasing with growth of turns of the engine. Noise of the pump can be audible on all transfers.

• Hydrotransformer noise – howling noise which is usually audible only on the motionless car at inclusion in a transmission of ranges D (Movement) or R (Backing). Noise of GT increases with growth of turns of the engine.
