5yr/53,000mi doing alot of Maintenance

[Gear Jammer]

Well i will be chaneing the oil,coolant,tranny,rears and fuel filters.

What type of tranny fluid should i use??? (6speed) The owners manual says it takes auto tranny fluid is that right?? All the stick i know just take gear oil. This must be a new thing out or something.

What about for the rears???

What about the coolant???


BTW the truck is a 2004 f-350 4x4 SRW.

Just to let you know i don't care what things cost as long as I'm getting the best.

Anybody know about the tranny. I know i dont have a filter but what about a new gasket for when i drop the pan???

For the differential, front and rear I would run synthetic. I am pretty sure the rear requires synthetic. Front, I run 75W-90. For the rear I run 75W-140. Most synthetics don't neet a friction modifier added if you have the limited slip, but if you get chatter then just add some. The manual transmission does call for ATF. I would use a good synthetic there also.

Your truck has the Motorcraft premium gold engine coolant this is what i put back in mine

My dad has an O.B.S. with a man trans and has run Amsoil ATF full synthetic in it since new.

I run the Amsoil severe gear 75w90 in the front axle and the 75w140 in the rear. I also put 2 bottles of the Ford friction modifier in the rear when i do the service when the rear is a limited slip. Amsoil says you dont need to put in the friction modifier unless the the diff starts to chatter but i have had the chatter a couple of times so i just put it in

Hope this helps

Your transmission holds 13 pints if you have the cooler, and 12 pints if it does not. The front differentials holds 5.7 pints, and the rear holds 8.4 pints if it is a DANA 80, and holds 24 pints if it's a DANA 135. The transfer case holds 4.0 Pints and that is ATF also. The manual doesn't have a pan. You have a fill plug near the top of the case, and a drain plug near the bottom of the case. Torque spec for both plugs on the trans is 26ft-lbs. For conversion purposes 2 pints=1 quart.

FYI, the friction modifier limits the "lock-up" capability of the factory worthless LS. The friction modifier is strictly for the chatter

why do you guys run the diff. weights in the rears
