  – horizontal an oil pipeline on a case and their connections,
  – adjusting bolt of the drive of forward planetary transfer,
  – laying of the lever of gear shifting, and also lever of a reduction of transfers,
  – laying between a back part of a case and control connections,
  – laying of the oil pallet,

There does not come gear shifting or lack of draft. To check oil pressure in the automatic transmission. To check serviceability of hydrokinetic transfer and the oil pump; in case of need to remove and clear the transmission. To check whether there is no mechanical damage of an entrance shaft of the automatic transmission, turbine, a case of coupling or forward planetary transfer.

To check oil pressure in the automatic transmission. To check serviceability of coupling of transfer of a backing and direct transfer, and also the drive of reverse planetary gear.
Lack of draft and gear shifting in provisions "D", "2", and also "1", whereas in situation "R" draft normal. To check oil pressure in the automatic transmission. If pressure too low in provisions "D", "2", and also "1" then to check the drive of reverse planetary gear, and also consolidation of coupling of planetary transfer. If pressure normal, then most likely came mechanical damage of forward planetary transfer or entrance shaft of the automatic transmission.

Strong friction of the drive in all provisions of the lever of gear shifting. To adjust the speed of idling of the engine in situation "D" for obtaining values 650 – 700 about / min. To check oil pressure in the automatic transmission.
The car tends to automatic start-off from the place forward ("pulls") except for provisions "P" and "R". To check serviceability of coupling of advance. To remove and clear the transmission.
Strong mechanical noise during the movement. To check serviceability of hydrokinetic transfer. To put the parking brake in action, and also to include a hydraulic brake of the car. If in situation "N" noise normal, and in provisions "R" and "D" noise strong also increases with increase in speed of the engine, then it is necessary to replace hydrokinetic transfer. Otherwise it is necessary to remove and clear the transmission.
Excessive mechanical noise during the movement. The internal mechanical damage of the transmission demanding its removal.
Sudden emergence during the movement of abnormal noise and interruptions in draft. To check oil level. If level normal then to check an oil filter. If the oil filter is not too polluted, to check serviceability of the oil pump.
The tape of a brake is not clamped in provisions "R" and "D" at too large number of turns of idling of the engine, and also at the correct gear shifting. To check oil pressure in the automatic transmission. To check serviceability of coupling of transfers of a backing and direct transfer. To check serviceability of the drive of reverse planetary gear.
The tape of a brake is not clamped in 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 then to check the drive of reverse planetary gear. If braking correct then 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 situation "R". To check functioning in provisions "2" and "1". If functioning normal, then is damaged the unidirectional coupling; it is necessary to remove and repair the 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 the automatic transmission at full opening of a butterfly valve during acceleration (kick-down). If normal then to remove and check hydrokinetic transfer, and also the unidirectional coupling.
