15.5. Diagnostics of an automatic transmission

Infringements in transmission work can be caused following reasons:
– Poor-quality adjustment;
– Malfunctions in hydraulic system;
– Malfunctions in mechanical system;
– Malfunctions in the computer or its electric chain.
First of all check up level and an oil condition in a transmission and adjustment of draughts.

The preliminary control
Make a trial trip for transmission warming up.
Check up oil level in a transmission.
Check up frequency of rotation of the engine idling.
Check up freedom of moving of a cable of an accelerator and if necessary adjust.
Check up work of the mechanism of a choice of transfers.
Be convinced that there are no leaks in installation sites of linings and sealing rings in a transmission.

Preventions
The burnt smell of oil is a pollution sign its small particles as a result of deterioration of frictional overlays of elements of management of an automatic transmission. It should guard, as, probably, transmission major repairs is required.
If oil level in an automatic transmission below normal in the oil pump air will start to arrive that leads to formation of a mix of oil with air. It in turn will cause decrease in working pressure in a control system, проскальзывание frictional elements of management of a transmission and the gear changes stretched in time.
If level of oil more normal as a result of rotation of gear wheels of planetary mechanisms plentiful foaming of oil will begin that leads to the same consequences, as well as in case of low level of oil.
Formation of a mix of air with oil finally will cause an overheat and oil oxidation that will negatively affect work of valves and frictional elements of management. Besides, foaming becomes the reason of the raised emission of oil through сапун that can be wrongly accepted for leaks of oil from system.
