Proper fluid in the Allison

I just found 1 5 gallon pale of QUATRASYN locally, and surprisingly it isn't priced that bad. $24 a gallon, but it only comes in a 5 gallon bucket he said. So it isn't that much more than regular DEX/MERC fluid which is about $19 a gallon at WAL-MART. And all GM vehicles from 06+ have had DEX VI in them from the factory.
No idea on how it would work in a built Ally, but it, or Redline MTL, would probably be far superior to the commonly used synthetic 5W-30 in the transfer case. Redline uses POE base stock which can take far more heat than the commonly used group III and PAO base stocks used in most synthetic motor oils. If you want to compare, look at the NOACK evaporation tests results. It's good stuff
FWIW, I have been running MTL in my 241 behind the Cummins for a couple years now. It still looks as good as the day I poured it in.
I plan on it. I have to run down that way the end of the week, so I will probably pick it up then. One place I called try to get me to buy some BP oil as they said they don't sell much of the QUATRASYN.
About to get the 2002-era Allison filled with fluid during a rebuild and I'm looking for some current information on recommended fluid.
Ah, sorry I should have specified. Whatever comes in the PPE Stage V kit. I'm not sure what that is. I've also got the ATS C5 clutch pack going in as well.
Thanks guys. All of the older threads have indicated Dex III as well but I wasn't sure if anything has changed since then. Looks like I'll be picking up some Dex III.
It was mentioned earlier that Dex VI was junk. But I got over 200 000km on mine with just regular filters and one oil change at a 450-500hp tune, trans-go and an ATS converter. Never figured the trans would outlast the engine lol!! Running Mobil 1 Dex VI.
No idea what to run after I get the trans built. I have a pail of transynd sitting in my garage but not sure if it is any good to run in the 6 speeds-I have heard mixed reviews.

I've had really good luck with quatrasyn. It's been in for about three years and 60,000 miles and is still nice and red when I change the spin on.
It's been a while since I bought it but I think it was around 10.00 a gallon cheaper than transynd. I had to buy it in bulk as it only came in 1 gallon jug, 12 gallon or 55 gallon drum. I bought the little barrel and split it with another guy.
