transmission fluid
I have a 2004 5.4 4x4 truck. It takes merc V to my knowledge. I can't seem to find merc 5 anywhere. Is merc V my only option for my trans and if so, where can I look to get some besides the main sources like autozone, etc.

Most any autoparts store should carry some sort of mercon v. I will being doing a trans fluid change shortly so have been looking at prices anytime I'm in a auto parts store just to compare. Everyone I have been to has some sort of mercon V. Walmart had both the Castrol brand and their house brand supertech. Advance Auto has Castrol on sale right now $5.19qt. Autozone had the Castrol and another brand I dont remember which, even my tiny napa had their branded mercon V. Also amazon has several options with free shipping the cheapest being Havoline at $54 for 12qts. Also just noticed tonight if you happen to have a Pep boys nearby that you can use their coupon codes online on mercon V and make the Castrol about $4.50/ qt. I am also looking at the 5 gallon pail of Tectus Mercon V on amazon which would allow me to do multiple drain and refills to get it all changed out but I cant really find out much info on it. Mercon V should not be that hard to find, good luck.

To get the pep boys discount you have to do an online order 25% off $75 order or 35% off over a $100. If you only doing a single pan drop you wont need that much worth but if your doing it twice or doing a flush you will. Not sure about the quality of the Pep Boys duralast trans filter so cant recommend whether to add that into the mix or not.

I ordered 16 qts of Castrol MercV from O'Reilly's when they had a fire sale. I did the pan drop, installed a drain plug. Every oil change, I'll drain the pan and add new fluid until my 16 qt stockpile is gone. Poor (or lazy) man's flush.

But there will always be an argument that 5 quarts of new fluid is better than doing nothing at all.

Not a flush though, as once you empty the pan, and add lets say 5 quarts, it mixes with about 7 to 8 "dirty" quarts. Then, on the next pan drop, the cycle repeats, so you'll never get a complete "fresh" change of transmission fluid.

Using Mobil 1 ATF
I used Mobil 1 ATF when I changed my fluid/filter @ 30K. Works great and I recommend if you do any towing with your truck. Mine took 4 qts-06 F-150 with 5.4L.
