Your car does not have a dipstick, your car has a plug that must be removed from underneath the car. The fluid level needs to be even with the threads in the case itself.
Note #65 in this illustration.
Here is how you should be checking the level.
Caution: The engine must be running when the transmission fluid fill plug is removed, or excessive fluid loss will occur. Transmission fluid may be hot. Since the actual fluid level is unknown, stand clear when removing the fill plug. Have a container ready to capture any lost fluid. Do not turn the engine off with the fill plug removed, as you can be injured by hot transmission fluid being expelled out of the oil fill opening.
