[QUOTE="Chris@FreedomMotorsports, post: 709421, member: 8341"] I have done some research on this one as it is very unclear in the manuals, etc. After talking to the Ford tech at my local dealership, it is even more unclear...lol But here is what I have come up with. First, for the use of Mercon V or LV. The LV is an upgraded version of V with a little less overall viscosity, nothing more. But the viscosity of the LV matches up with the Ford transfer case fluid. From what I understand, there are actually two different transfer case possibilities in the Raptor. The first actually has a Ford logo stamped into the back half of the case and that is the one that requires the Ford transfer case fluid from the factory. The other, without the stamp, requires transmision fluid and calls for Mercon V equivalent. Now, that being said. I was told by that technician that for the transfer case itself, those fluids are so close in formulation that using one in place of the other doesn't hurt anything. There is only a slight difference in viscosity between them and there is only less additives in the transfer case fluid than the transmission fluid overall. So, in essence, you can actually use any of them in the Raptor transfer case without causing problems That being said, my recommendation for the use of AMSOIL Fuel Efficient transmission fluid is because it is the fluid that meets the Mercon LV application for the 6R80 transmission and when someone is ordering the fluid for a full machine flush, I can send a case of two 2.5 gallon jugs. This provides enough transmission fluid for the full flush and then leaves enough left over to perform the transfer case swap. [/QUOTE]
