Long-term synthetic oil is used to lubricate the parts of manual gearboxes. Unlike the engine, the oil in the gearbox is practically not consumed. If there are no traces of oil leaks on the outside of the gearbox, then its level has not dropped. However, the oil level must be checked from time to time. In automatic gearboxes, the working fluid level can only be checked in the main gear, the level in the gearbox must be checked at a service station using a special diagnostic device MUT II.
Checking and repair
Oil may leak out due to leaky seals. Check the connections in the following places:
- between the gearbox and the engine;
- the place where the shafts exit the gearbox;
- filler plug;
- drain plug.
All gear units of the gearbox have a very long service life. If the gearbox fails, it must be repaired at a service center, since repairs must be carried out by qualified specialists using a special tool.
If you decide to do the repair yourself, keep in mind that for high-quality repair of the gearbox, you need accuracy and a very clean work area. In addition, special tools will be required for the repair.
