You need to figure out which transmission you have the newer 2007 NPRs use a silicone fluid (They have vertical door handles like the picture) The earlier ones used Dexron III
Most of them you have to drop the trans pan and drain the fluid. Change out the filter, seal it up and fill through the dipstick tube. If you know a good TIG welder in the area you can have a drain plug added to the pan.
