I am about to replace the fluids in the differentials and transfer case myself.

Front differential needs synthetic 75w90. I can purchase at any auto store in my area for about $15/quart.

Transfer case needs Shell tf 0753. Can't find this anywhere other than the dealership. They quoted $48/quart. Is this reasonable? And is there another place I can purchase it?

Rear differential is electronic LSD. Do I just use the same oil as in the front?

I'm a noob with Range Rovers. Been a Toyota guy my whole life until now...these things are different beasts!

Thanks much!

The rear electronic diff requires this

Castrol SAF Carbon Mod Plus

Just wanted to give anyone else who decides to do this some photos of the products I purchased. Again, I drive a 2012 RR HSE Lux 5.0L V8

I spent the extra money and bought the oil from a Land Rover dealer in Houston. The prices are absurd, but I'll sleep better knowing I'm using the correct products. The front differential takes regular ole synthetic 75w-90 gear oil, so I saved some money by purchasing that from Advanced Auto for $11 for a quart.

I included front and back photos of the bottles so you can see exactly what you need.
