Question, and it surely belongs here

Has to do with type of oil to use for Front/Rear Diffs vs Transfer case (center diff). FSM calls for "Toyota Genuine Diff Gear Oil LT 75W-85 or equiv). And for the transfer case "Toyota Genuine Transfer Gear Oil LF SAE 75W or quiv". Is there a difference between the Diff Oil and Trans Oil? I watched
@MScruiser youtube vids and it seems he used the same Mobile 1 Synthetic 75W-90 in all three applications (front, rear, and trans/center). Looking to confirm the gear oil is the same in all three, plan to do this service soon.
