15 qts of the oil of your choice. I use Valvoline Extreme Blue. Tell you the truth I can't tell the difference between that and plain ol Rotella honestly so next time I'll save my money and go back to dino.

Trans, I don't know I had a shop flush and change mine.

I did the rearend the other day and it took almost 5 quarts of Mobile1 75-140 and 8oz's of friction modifier. The front should only be alittle over 3qts of 75-90 and no fm. The transfer case I haven't done yet but I think its only a couple of qts of ATF. Look in the maintenence section and there is a write up on all of it with good pics also.

The trans should only take Mercon/Dexron III , not Mercon V, this is still available at Napa as ATF, they can't put Mercon on the label because Ford owns it. You will need 21-24 quarts for a complete flush. Don't put 8 oz of modifier in the rear end if you have LS!!!! This is why Ford's limited slip get's a bad reputation, add 2-3 oz and do some tight figure eights in a parking lot, if you hear chatter add 1 oz at a time until the chatter goes away and your LS will work as designed.

Thanks guys for the help. Hopefully I can get some time to do the much needed maintenance.

Don't put friction modifier in if you don't have a limited slip rear end!
