How do you put transmission fluid into your 2001 Isuzu Rodeo?

For most isuzu rodeo transmission are sealed transmissions, (they do not have a dip stick) look under the truck and you will see two bolts on the transmission oil pan,(one smaller than the other) technically you're supposed to refill the oil with a special pump at mechanic shop. But there's a trick to do it yourself, on the driver's side of the transmission is a plug with a sensor( remove the sensor and fill from there. You will need an adjustable wrench..
