Yes. There is not a dipstick.
Can a dipstick assy be ordered or a special tool ordered to check the transmission level ?
No special tool needed and there is no provision for a dipstick. The picture below shows the transmission as viewed from the passenger side. There is a plug at #65 in the picture below. (11 mm or 7/16" wrench). Remove this plug with the engine running and the transmission in Park. Transmission fluid should dribble from the hole with the plug removed if the level is full.
Picture below shows the fill cap at arrow.
