Jimmiee, I just got back from having the flush done at Jiffy Lube! It took 16.5 quarts. I took advantage of going during the Cowboys game today so there wasn't much of a wait at all! I was able to watch the whole process and they let me go down in the bay so that I could get a good look of my undercarriage while the flush was in progress. I think I caught it none too soon! The fluid was really dark, not quite black, but close! I'm going back next Sunday to get the transfer case and diff done. The price before tax was $182, then they gave me a 20% veterans discount for a grand total of $155.50 including tax!
