Tranny fluid change
Hi Ya'll,
I have a 2004 F350 DRW V10 gas and I'd like to change the auto tranny fluid out to a synthetic. It is my understanding that there is no paper filter anymore in these transmissions, just a cleanable screen. Please correct me if I'm wrong.
Secondly, I plan on just draining the pan and converter, then replacing the fluid. Could someone let me know how many quarts this will take.
I also intend on replacing the rear axle fluid to synthetic, any idea how many quarts this will take?
Reccomendations on fluid would be apprecuiater on both tranny and diff.
Thanks.

I believe that the fluids on the 2004 are already synthetic. I don't own one so can't say either way.
You should use a fluid that meets Ford spec. I believe that you will need a Mercon V tranny fluid and the diff fluid is a syn that is something like 75W90 or 75W140?
I like the Mobil 1 and Valvoline synthetics, but any syn meeting spec should work fine.
Don't know your model but I bet in a full fluid change you are looking at about 12 to 16 quarts for the tranny and 2 or 3 for the diff. You may need limited slip additive for the rear if you have a LS diff. Some diff fluids already have it but typically when I use Mobil or Valvoline I need to add one tube of additive. I think the brand I use is StaLube, looks like a toothpaste tube.
Good Luck,
