Search of malfunctions - the general information

At failure detection of automatic transmission first of all check level of working liquid (address to 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 — it 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 to a mode of safe functioning, bringing thus the corresponding code (or codes) in memory of the control unit. It is possible to consider codes 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 established on the engine.
