The tranny dip stick is behind the eng. on the passenger side between the firewall and motor.Its not easy to spot because it sits down in a little bit and is black in color.Add oil where you pull the dip stick out and not to much oil at a time.You will need to get a small funnel that will fit into the tube.Once you have found the it,check the oil level with the eng.running and hot to get the correct reading.Add a little at a time being sure you dont overfill.Recheck the level after driving and add more if nessesary.Hope this helps.
