Checking the level and replacing the working fluid in an automatic transmission Renault Sandero

The gear oil poured into the gearbox is designed for the entire life of the vehicle and there are no operations for checking the level and changing the oil in the maintenance schedule.
At the same time, we recommend that you check the oil level in the gearbox at each service and, without fail, if an oil leak is detected from the gearbox.
We perform work on a viewing ditch or overpass.
We check the oil level through the control (filler) hole on the cooled gearbox. The control hole is located on the front wall of the gearbox housing and is closed with a threaded plastic plug. 

Gearbox inspection plug location:

Access to the control hole on cars with engines 1.4–1.6 (8V) is possible from above from the engine compartment, on a car with an engine 1.6 (16V) it is more convenient to unscrew the plug from the bottom of the car (with the protection of the power unit removed).
With a rag we clean the gearbox housing around the control hole.

Unscrew the control hole plug counterclockwise. 

The oil level in the gearbox should be at the level of the lower edge of the hole, which can be checked with a finger. If necessary, adding oil to the gearbox can be done from below the car with a syringe for filling transmission oil (on vehicles with engines 1.4–1.6 (8V), oil can be added from above, from the engine compartment using a funnel and a hose inserted into the control hole) .
Add oil of the same brand that was poured into the gearbox.
When adding oil from the bottom of the car, remove the protection of the power unit.

Add oil to the gearbox to the lower edge of the hole (oil will begin to flow out of the hole). 

When the excess oil flows out, remove the oil drips with a rag and wrap the cork.
If it is necessary to drain the oil from the gearbox (for example, when replacing the right wheel drive oil seal), clean the gearbox crankcase around the drain hole. We substitute a container with a volume of at least 3.5 liters under the drain hole.

We unscrew the drain plug with a “8” tetrahedron and drain the oil into a container.

A copper washer is installed under the plug for sealing.
At the end of the drain, wrap the drain plug. After completing the repair work, pour oil into the gearbox through the control hole and wrap the plug.
