Once the pan is off, the only tool you need is a small bladed screwdriver to pull the clips out that hold the solenoids. One solenoid is spring loaded (just 1 lb of force), the other not. First snap off the electrical connectors with your fingernail.
You might consider installing the Sonnax 4L60-LB1 boost valve while you have the pan off. It will increase line pressure across the board which will give you slightly firmer shifts, reduce slippage during shifts, thereby reducing heat and potentially increasing the life of the trans. About $30 and the only tool you need is a snap ring plier.
