Where does one check the gear oil level on an 2001 Kia Sephia 1.8L?

To check the gear oil level on a 2001 Kia Sephia 1.8L, locate the transmission oil fill plug, which is typically found on the side of the transmission case. Remove the plug using the appropriate tool, and the gear oil level should be at or near the bottom of the fill hole. If oil drips out, the level is sufficient; if not, you may need to add oil until it reaches that level. Always ensure the vehicle is on a level surface when performing this check.
