That's what I'm trying to tell you, there may not be a level plug on your transmission. Traditionally automatics had a dipstick to check the oil level with Hot and Cold markings for the oil level and you mostly used the dipstick hole to fill or top up the fluid. But manufacturers have been doing away with these dipsticks because their auto boxes are sealed systems.
If you don't have a dipstick on your auto transmission then you will likely have to check the fluid level on a ramp similar to what is shown on that video i posted the link to.
