Oil leak:

The oil used in the transmission, usually dark color. Therefore do not mix it with engine oil which can get on the transmission from the engine. For definition of leak of oil purify dirt from a case of the transmission and adjacent areas and carry out a control trip at a small speed that oil was not transferred by an air stream. Install the car on a viewing hole and define the place of leak of oil.
