No dipstick. They say take it to the dealer to have it checked. Doing it yourself, the vehicle needs to be level (they say on a lift), remove shield, take out plug on the "side" of the transmission, if oil comes out, it is okay, if not, add fluid from the top cover plug till it runs out, then replace the plug...oh yes, use some thread sealer as the case is cast alum. and the plug is steel, dissimilar types of metal will cause it to seize.
