    Under the vehicle on the passenger side, the transmission has two plugs. The lower one is the drain plug and the upper one is the fill plug. To check the level, stick your finger in there and the fluid should be right at the edge of the bottom of the opening. with the engine running and in park position. The easiest way to fill is with a 3 foot length of clear tubing attached to a funnel that you hang on the upper part of the passenger door. Start the truck and shift thru all the gears back and forth then leave it in park with the engine running. Put a pan under the tranny, remove the plug, insert the tubing into the opening and slowly pour Dexron ATf fluid (its a GM tranny) until it dribbles out the opening. Shift thru all the gears again and repeat the process Until it won't take more fluid. BE CAREFUL and don't get any ATF fluid on the paint!.
