You are so wrong that there is no Posi gear lube. It has been on the market for about 15 to 20 years. Standard oil markets it, Quaker state markets it, and GM markets it in 1-quart containers.
GM part # 1052271 80W-90 Rear axle lube. GM part # 1052358 Limited slip differential lube additive. The additive is used with the rear axle lube is severe cases where the stick slip symptom is heard. Quaker state weight of the lube is 75-90 and is green is color. Brown or dark brown color means that the fluid is burnt and needs changing, as it can no longer provide adequate lubrication for the bearings or gears. You need to change the rear fluid, and then find parking lot where you can drive in figure 8 patterns for about 10 to 20 times. This will work the new fluid into the clutch and disk plate in the posi. You may need to change the fluid again and repeat above after 500 miles. Good luck.
