Check of level of oil of a mechanical transmission

At the left: the control carving stopper (1) mechanical transmission is located in the movement direction on the right on a half of height of the case of a transmission. The carving stopper of a drain opening (2) is located below on a transmission.

On the right: level of working liquid in a tank of the amplifier of a wheel (2) is necessary for checking at the working engine. If marks of a tank are not visible, it is necessary to turn off a cover of a tank (1) and to check the shchupy. Shooters point to marks.

In a transmission oil is not spent how in the engine, and can flow out only through defective consolidations. If on the transmission case outside it is not visible any dirty places impregnated with oil, this point of checkup is finished. Otherwise it is necessary to check oil level. The carving stopper of aspic (and control) openings is at the left in the movement direction on a half of height of the case of a transmission near a power shaft.


  1. The car to lift in horizontal situation.
  2. To turn out a stopper a natural internal shestigranniky 17 mm.
  3. If transmission oil starts to follow at once, with its level everything is all right.
  4. If is not present, it is necessary to push a finger in an opening and to check, whether gets opening oil: sufficient level of oil.
  5. At bigger shortage to add the corresponding transmission oil on filling or in a workshop.

For check of level of ATF to extend щуп from the directing tube (3) located behind at the left in a motor compartment. At warm ATF level of liquid should be in a normal range (1) between two marks. On the extension piece (2) it is possible to check level and at cold ATF.

 Help: autographic filling by very viscous transmission oil by means of a funnel and a long hose even at warmed-up oil represents considerable test of your patience and for this reason it is not recommended. It is better to use for an oil dolivka special canisters or a syringe with the built-in hose.

Correct grade of transmission oil

You do not need to reflect on replacement of transmission oil more. The transfer mechanism is supplied with the tank from which possible impurity are caught by means of a magnet.

However transmission oil should correspond to certain requirements. Audi orders use of oil of a class of viscosity of SAE 75 W-90 with the G 50 specification. It is a question of synthetic oil.
