Transfer case (PTU) spline grease 6G92M1C27AA. What is it ?

Just wondered what grease is part number 6G92M1C27AA, as advised by JLR manual for the input shaft splines in the PTU
I searched online but couldn't find it. Jules

Splines would normally use a molybdenum based grease, as it keeps the splines sliding without wear, which is why it's used in CV joints. Hyundai Ioniq 5 Ultimate. The family car.

Thanks , so both Volvo and Sachs sell a grease specifically for splines, just like JLR. One is a white grease. I wonder who makes it and what is the spec.
Nodge recommends a moly grease.

I've seen alot of splines lubricated with copper grease, but that doesn't have the right properties I'm pretty sure. Jules

Any grease is better than no grease. However copper grease isn't a lubricant as such, it's designed as an anti-sieze coating, but will also function as a mild lubricant at high temperatures, which is why its used on brakes.

I'd always use a moly based grease on components which contain sliding elements, splines falling into that category. The reason being that microscopic moly particles are slippery, and so small they literally bold to the metal, so the components to be lubricated slide easily on the moly coating, massively reducing wear.

Lithium based greases are more useful for lubrication of rolling components like bearings, where the grease is carried between the various elements requiring lubrication. If lithium is used on splines, the movement of the splines will tend push the grease out to the ends of the movement area, where it can't do what its been put there for. Hyundai Ioniq 5 Ultimate.
