Did you drain it already? Should be a port on top of the trans to fill. Removing the passenger wheel and splash shield will help gain access. You might be able to access the fill port from the engine bay using a long funnel. Then once the fluid is added, start the car and go through the gears a few times and warm up the vehicle. You can now get underneath to pull the fill plug on the bottom side of the trans casing to check the level. HTH's.
