Transfer Case Fluid Capacity

Does anyone know how many Pints or Quarts of fluid is in the Bravadas transfer case? The owners manual doesn't state fluid capacity for the transfer case, just to fill it to the bottom of the filler hole. I want to upgrade to redline racing oil, D4 ATF fluid, but I don't know how much to order?:confused:

Any help would be great.

Daubs

should be 2-2.5 quarts

I don't know if there's a synthetic/aftermarket fluid for the Bravada transfer cases - I think the cases were different pre 1996 or 97 - don't remember exactly which.

Far as I'm aware, the only fluid approved for the transfer cases is the GM AutoTrak fluid (I think that's what its called anyway).- it looks like blue sno-cone mix. When I changed mine the only place I could find that fluid was at the dealership.

If you have a pre 1996 or 97 Bravada, the fluid may be different. Again, I don't remember exactly when they changed the transfer cases.
