There are some workshop manuals floating around for download for the '03-'06 Ram that are free and will provide the information. They are actual factory manuals are are excellent. I noticed that you have the 4.7 in your truck which would have the 45RFE trans in it. That transmission has no bands in it. It uses hydraulic clutches and overrunning clutches to obtain the different gear ranges. I hope this helps. Nice truck by the way.
