How do you check manual transmission oil daewoo nubira?

To check the manual transmission oil in a Daewoo Nubira, first ensure the vehicle is on a level surface and the engine is off. Locate the transmission oil filler plug, typically found on the side of the transmission casing. Remove the plug, and if oil begins to seep out, the level is adequate; if not, you may need to add the appropriate transmission oil until it reaches the fill level. Always replace the plug securely after checking.
