Consider yourself among the lucky few; the pump rub problem has nothing to do with the fluid that's in the case. If the clip keeping the pump from contacting the magnesium case breaks, it will rub a hole in the case weather you have $2/qt Dex III dino or the most expensive synthetic 5W30 you can find.

So a suggestion by Rockland Standard Gear with no data to back it up is a "study"? Have you read the TC fluid sticky on DP?
You need to switch your avatar back I liked the old one better

The sticky at DP is a compilation of manufacturerers recomendations on their products driving them as they were intended. It was put together by a person who does not build or repair them.
I could do the same thing on heart transplants and sticky it on a medical website and it would look good cause I copied all the words correctly and made a good presentation. Would you let me do a transplant on you?
Simple fact is you will probably be all right with ATF IF you check the level on a regular basis. Most people don't including me. Therefore I use motor oil which has less of a chance to vaporize. I also believe it lubricates better under adverse driving conditions.
ATF was originaly filled in standard transmissions and then later in transfer cases for better mileage, not because it was a better lubricant.
We play hard with these trucks and need all the help we can get to keep them from breaking or wearing out parts prematurely. This is what the aftermarket hot rodders do and the manufacturersd learn from us; not from a guy behind a desk copying and pasting brochures and his claim to fame being a trans cooler hung upside down.
Again all I have said is that that claiming the 5-30 is better then ATF is BS and has not be proven. All we know is that it doesn't evaporate. FYI I have 5-30 in my TC, just to try it. I've never lost a drop of Syn ATF out of my TC. Even with several 2K mile plus nonstop trips at times running 90mph for a few hrs at a time.
Can I point out something kind of obvious? If you look at the MSDS for most 5W-30 oils their flash point is higher than that of synth ATFs, usually around +10* F. Many of the manufacturers dont have a boiling point or specific vaporization rate for these fluids but flash point is the absolute threshold, so if it takes 10 more degress to actually ignite motor oil that correlates to a big difference in the way that said chemical handles heat.

I swapped to 5w30 in my T case last November. I put 3qts in through the speed sensor as well. After reading I figured I should check how much was left as my output seals sweat a bit off and on. When I pulled the plug I still must have had damn near 3 qts in there. So I refilled with 3 qts of fresh 5w30. So far so good.
I've been running 5-30 Amsoil in mine for a while. No issues. I check it once in a while and no loss thus far.
What 5w-30 would you suggest that is more readily available?
Any opinions on Royal Purple? Is it even synthetic?
I use Rotella dino in engine, and used to use Mobil 1 in tranny and tcase.

What sticky? The one that Mike L. started about using motor oil instead of ATF? I can't find anything else about TC fluid. Maybe I'm blind.So a suggestion by Rockland Standard Gear with no data to back it up is a "study"? Have you read the TC fluid sticky on DP?

There is a sticky under fluid and maintenace at DP.
question: it calls for 4.1 or 4.2 pints which is basicly 2 quarts why are all of you filling with 3 quarts?
