[aussiestroker]

What sort of oil's are you guy's using? Do you add anything to transfer case, or use a different oil grade ? Thanks

I'm getting ready to put amsoil synthetic ATF in my rebuilt zf5 but not sure if zf6 takes the same.

Yes it uses ATF, am going to use synthetic more wondering about additives to box or transfer.

My +330k mile ZF6 was chewing pilot up bearings every 10k miles, so I just replaced it with a Midwest Trans. Shifts like a new truck now! FWIW, it's had Mobil 1 in it since 100k miles and has towed at max GCVW with more power than stock most of its life - and I only clutch 1rst gear.

I ran whatever came in it till 170K. Then I did a drain and fill with autozone semi synthetic. No difference. Maybe I should have went with full synthetic

I'm gonna drive it tommorow. I'll tell you how it shifts. But going from a junk trans to a new one will probably be a big difference anyway. I went with amsoil for the price vs royal purple and it is approved for warranty use in allison trans and most all chevy and dodge transmission as well as a few fords that take ATF.
