Hey all, I'm a bit overdue on my service i've been waiting for the weather to break to get out and do it. I'm going to be ordering all my fluids for the truck tonight hopefully if i can get some answers ! I've got a 2006 Vortec Max. believe it's the 4l70E right? does anyone know the fluid weights and capacities I should be runing for the transfer case, rear, etc.... I'm gonna be running amsoil in everything, well everything except the motor oil I use royal purple for motor oil but they have that prefered customer discount thinng so i'm going to be using Amsoil for everything else. Any help would be appreciated.
