However, during the operation of the vehicle, it may be necessary to drain the oil and replace it, for example, when repairing the gearbox or when there is a significant oil leak from the gearbox, when it is not possible to add oil of the same brand that was poured into the gearbox. It is recommended to change the oil on a warmed-up gearbox.
We clean the lower cover of the gearbox from dirt.
Place a wide container with a capacity of at least 3.5 liters under the lid.
Using a 13 mm head, loosen 10 bolts securing the cover, but not all the way… …and drain the oil into a container provided.
After draining the oil, completely unscrew the bolts and remove the cover.
We clean it from deposits, wear products of parts and traces of the old gasket, and also clean the mating surface of the gearbox housing. We replace the gasket with a new one or apply a sealant-former of the gasket to the mating surface of the cover. We screw in the bolts and tighten them evenly to the prescribed torque (see Appendices).
Fill the gearbox with transmission oil to the required level (see Checking the level and adding oil to a manual transmission).
