How do you change the transmission fluid in a 1999 dodge ram 1500?

To change the Transmission Fluid in a 1999 Dodge Ram 1500, start by warming up the engine to thin the fluid, then turn it off and allow it to cool slightly. Place a pan under the transmission pan, remove the pan bolts, and carefully lower it to drain the old fluid. Replace the filter if applicable, clean the pan, and reattach it with a new gasket. Finally, refill the transmission with the appropriate type and amount of new fluid through the dipstick tube, checking the level as you go.
