There are some similar size bolts going into the transmission from the side that hold the right-hand axle cover to the case.
The drain plug is inserted vertically into the bottom of the right axle cover about 3-4 inches from the filter. Number "4" on the picture.
The suction pickup is on the left side of the transmission case, with a hose leading from it. There is a banjo fitting with two O-rings and a wire mesh screen on it to filter out particles from the hydraulic fluid.
