The car tends to an automatic troganiye from a place forward ("pulls") except for the provisions "R" and "R". To check serviceability of coupling of advance. To remove and clear a transmission.
Strong mechanical noise during movement. To check serviceability of hydrokinetic transfer. To put in action the parking brake, and also to include a hydraulic brake of the car. If in the situation "N" noise normal, and in the provisions "R" and "D" noise strong also increases with increase in number of turns of the engine, it is necessary to replace hydrokinetic transfer. Otherwise it is necessary to remove and clear a transmission.
Excessive mechanical noise during movement. The internal mechanical damage of a transmission demanding its removal.
Sudden emergence during movement of abnormal noise and interruptions in draft. To check oil level. If level normal to check the oil filter. If the oil filter is not too polluted, to check serviceability of the oil pump.
The brake tape is not clamped in the provisions "R" and "D" at too large number of turns of idling of the engine, and also at the correct gear shifting. To check pressure of oil in an automatic transmission. To check serviceability of coupling of transfers of a backing and direct transfer. To check serviceability of a drive of reverse planetary gear.
The brake tape is not clamped in the provisions "R" and "D" at too large number of turns of idling of the engine, and also at correct a clip of tapes of a brake in provisions "D", "2", and "1". To check braking by the engine on the 1st transfer. If braking insufficient to check a drive of reverse planetary gear. If braking correct to repair coupling of transfers of a backing and direct transfer.
Tightening of tapes of brakes insufficient in situation "D" at too large number of turns of idling of the engine, and also at the correct tightening of tapes of brakes in the situation "R". To check functioning in provisions "2" and "1". If functioning normal, is damaged unidirectional coupling; it is necessary to remove and repair a transmission.
Too small acceleration and too small maximum speed, though engine serviceable. To remove hydrokinetic transfer and to check its technical condition.
Too small maximum speed at normal accelerations and the serviceable engine. To check functioning of an automatic transmission at complete opening of a butterfly valve during acceleration (kick-down). If normal to remove and check hydrokinetic transfer, and also unidirectional coupling.
