What to Use?

[Vick68]

Hey i'm just wondering what do I need to use in my tc, tranny, and diffs. Do I use dope in the dips? And manual tranny fluid or what. Thanks in Advance.

Use 80W-90 in the tranny, TCase and diffs.
If you have Limited slip diffs you need an LS additive.
EDIT: you say you have Manual Front & Rear lockers. I assume you mean selectable lockers you can activate. No they don't need a LS additive. Use the same 80W90 in all the mentioned places.
