I downloaded a maintenance service manual on a CD from the Hemi Club Web site. I printed out the task that I wanted to accomplish, the cd has over 8,000 pages of technical information on maintenance. The band adjustment is explained well and includes pictures where they are located; 1) one band is adjusted by removing the transmission oil pan 2) the other is on the outside drivers side of the transmission.
I flushed my transmission by 1)filling the newly installed pan with new ATF+4 fluid, 2) removed the return line from the transmission cooler back to the transmission, 3) ran the truck in gear for short time in gear. 4) repeated process untill I had 20 liters of old oil in bucket from transmission return line from coolers.
