Please,how can i measure gearbox oil (felicia1997 carbourater)

 

There is a speedo cable entering the gearbox. Remove the 9mm bolt securing it to the gearbox. Then carefuly remove the plastic speedo gear inside. You can check the level with this plastic gear. If i remember corectly it must be 4mm at the bottom of the gear to be correctly filled

Thank you,this picture is very useful
