Fluid question
 

hey guys,i got the tc in and bolted up with a new (well different) driveshaft,now i would like to go ahead and fill everything up while i have it on stands.What i need to know is what goes where?The tc is bolted to a turbo350 so dextron 111?front end(dana44)80-90?rear end same?thanx guys for all of your help!!!What a COOL BOARD!!

Re: Fluid question
 

Any GL-5 gear oil for the diffs and NP205 transfer case. 80-90w is a good compromise between 75-90w and straight 90w. The TH350 auto trans fluid should stay separate from the adapter and xfer case if the seals do their job.

If either diff has a clutch-pack limited slip, then limited slip additive is warranted.

I do know the rear has a posi in it,so what would you recomend?

Re: Fluid question
 

If you get 80-90 or 75-90 with the GL-5 rating it will be posi friendly.

Maybe. From the back label on Amsoil's "Synthetic Gear Lube SAE 80W-90":

Compatible with synthetic and petroleum gear oils and most limited slip differentials. If limited slip chatter occurs, add AMSOIL Slip-Lock friction modifier additive.

Boss, friction modifier is available at dealers, most auto parts stores, 4x4 acc stores, and speed shops. On line too, of course, but shipping on a couple oz would be ridiculous.
