I was checking my fluids on the differential, transfer case and transmission. I have a 98 Rodeo with a automatic transmission with no dip stick and had a hard time finding the filler check plug. I stumbled across a diagram showing the check/filler plug about 6 inches from the drain plug.






I talked with a mechanic today and the filler check plug is the higher of the two on the pan. Said it needs to be running in neutral on a flat surface.
Never knew how convenient having a dip stick was til now!
