8.2. Search of malfunctions - the general information

At failure detection of automatic transmission first of all check ATF level (see. Head Current leaving and service). If level is insufficient, check a condition of the corresponding epiploons. Attentively examine all hoses of a path of ATF, and also a cooler of transmission liquid and make sure of lack of signs of development of leaks. The only thing that can be still executed by strengths of the owner of a vehicle, is check/replacement of information sensors of a control system of AT, - before starting replacement of the suspected sensor, poll memory of the module of management, - all a little essential refusals are registered in memory of the module in the form of the DTC codes, and especially serious cases of TCM automatically switches AT emergency operation of functioning. Reading of the DTC codes is made by means of the special diagnostic equipment connected to the socket of system of onboard self-diagnostics (DTC) (see. Head of System of electric equipment of the engine). In the absence of access to necessary devices will try to define qualitatively at least the refusal nature (at level enough: electric/mechanical) for the purpose of simplification of communication with specialists of car-care center. It is not necessary to start AT removal as its diagnostics is represented possible only in the established situation prematurely.
