They are finding out its not the fluid, but more so on how the markings were on the gear set, wearing off not the fluid which is causing the clutch packs to make that growling noise. (hence the early flush). Now they are finding out that it could actually be the mfgr of the diff packs not correct. I just had my carrier replaced and so far so good. Although, once it hits 1500 miles again I am still flushing it.
