9.2. Search of malfunctions - the general information
At failure detection of automatic transmission first of all check the level of working liquid (address the Section Check of Level of Oil of Automatic Transmission). If level insufficient, check all epiploons. Attentively examine all hoses concerning transmission liquid and also a cooler and be convinced of lack of traces of leaks. The only thing that you still can independently make is to check and, if necessary, to replace the sensors concerning work of a box (temperature and turns). Before replacing any sensor, carry out reading of codes of malfunctions from memory of the control unit.
At rather serious breakage the control system of a box will pass into the mode of safe functioning, bringing at the same time the corresponding code (or codes) in memory of the control unit. Codes can be considered by means of the special equipment.
In the absence of that, define the malfunction nature (electric or mechanical).
Do not try to remove a box as diagnostics is carried out only on the box installed on the engine.
