Attentively examine the oil cooler and all hoses of a path of ATF, make sure of lack of signs of development of leaks. Check/replacement of information sensors of a control system of AT, and also replacement of components of the drive of the choice of the AT modes can be executed by forces of the owner of the vehicle. Before starting replacement of the suspected sensor, carry out a survey of memory of the control unit, - all a little essential refusals are registered in memory of the module in the form of the DTC codes, and in especially serious cases of AT automatically switches to 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 (DLC) (see the Head Sistemy of electric equipment of the engine). In the absence of access to necessary devices will be to try to define at least qualitatively the refusal nature (electric/mechanical) for the purpose of simplification of communication with specialists of car service enough. It is not necessary to start removal of AT as its diagnostics is represented possible only in the established situation prematurely.
