Install the Transmission Fluid right down the dipstick tube, but don't overfill, or you'll be replacing the gasket on the bottom of the transmission ($75 for a new filter, gasket and special ATF+4 tranny fluid). Be sure to check the fluid level with the tranny warm, truck idling and in neutral (set the parking brake). This dipstick is probably towards the back of the engine compartment on the left (passenger) side. Install the Power Steering fluid into the power steering reservior (the black cap has the little dipstick right on it) and again don't overfill. the reservoir should be on the top of the power steering pump on the front of the engine. Just follow the serpentine belt past all the things it powers until you find one that says power steering.
