O.T. FORD F350 ZF 6-SPEED FLUID

Thanks, I found several posts on a diesel site that recommends to use "ATF rated MERCON or MERCON/DEXRON III", not ATF rated MERCON V or "universal" MERCON/MERCON V. Mobil 1 ATF AND AMSOIL seem to be approved fluids also. Now I'm looking into rear axle fluid too--some folks are saying 75/90 and others are saying 75/140--both synthetic. It appears the diesels have the Dana axles (front & rear) that need the 75/90 and the gas trucks have the Sterling axles use the 75/140. Still trying to sort that out too.

Thanks again.

From my 02 owners manual:

Mercon, Not Mercon V, for the auto, 6spd, transfer case, or PS.

F250/F350 SWR 75w140 synthetic meeting Ford spec WSL-M2C192-A Part#XY-75w140-QL, Ford/Sterling axle, 6.9 pints

F350/F450 DRW Dana 80, 75w90 Synthetic, Ford part #XY-75w90-GLS, 8.5 pints

Both axles types are rated 100k mile oil change.

According to the 5th revision (final) Owners manual, the F250/F350 SWR is Sterling 10.5"

When I get time I'll look to see the difference in the covers as one has a different shape and number of bolts.

I don't have a on-line copy of the service schedule but I'm 99.9% sure it's a 100K miles as it was the same for the Gold anti-freeze.

All front 4wd axles were Dana 60 after Nov 2001 and very few before 11/01 as it was run out of stock on the Dana 50 then all were switched too Dana 60.

All F350 DRW was Dana 60 front and Dana 80 rear from 1999 (?) to 2004.

Starting 2005 F250/F350 SWR Ford switched too a front 4wd axle strut frame attachment to replace the leaf springs. I didn't buy the 2002 Dodge for that exact same reason. Bummer!

The 2005 F350 DRW continues with the front leaf springs.
