I got my truck at 55k miles from a chevy dealer and it appeared to have new tranny fluid, but i wouldn't count of what they put in there by any means.
In searches here on DP, transynd seems to be the popular choice becuase allison recomends it (but then again, why wouldnt they? they make it lol)
I take that with a grain of salt and wouldn't rule out others brand anyway, but thats a different post.
Anyway, I have 65k miles now and just installed a lift with 39'' tires, edge and plan of doing some light towing, figured a good fluid is a very good choice now.
I went to allisions web site and tried to locate an allison dealer/shop in the ABQ area and none of the 3 in the area will work on the ali 1000, they just do big trucks.
only 1 will actually sell me parts, and they want $33/gal for transynd, $9 filter which ain't too bad IMO.
Now since allison wont work on my truck, and the chev dealer is not an option for me (i wont let them touch my truck, much less pay their rates) I'd rather just do it my self with out the exchanger machine.
1. besides maybe not getting a 100% swap, and cons?
2. I know ppl say about 6 gals for the exchanger swap, but i've heard its less just draining the pan, how much is needed?

$9 for the filter is a good price, I got quotes from two Stealerships, one wanted $40 and the other $45. I bought two from the Allison distributor for $22. The Transynd is a little high, but not outrageuos, I paid $28/gallon.
I purchased the deep pan($55) and filter($19) as well and will use "Hoot's" method to flush it. Hope this helps.
You can drain the pan and refill with your choice of fluid. Repeat every 2-3k miles and after the third drain and fill you will have a complete change without having to pull and drain the torque converter.
Use the "hoot" method and get it done in one operation. Three regular drains and refills will get you a good mix but will not be as good as the hoot method and will take more fluid. Buy a 5 gal. pail from the Allison dealer and you should have enough to also change the T-case and have enough left for filter changes later.

You put transynd in your transfer case? I thought only dexron III. I have read some people are using motor oil and overfilling. Will transynd hold up as well as the other t-case fluid?

Transynd is a version of dex 3...just synthetic and formulated for Allison. just lube.
Anyway, the Allison dealer here had 5 gal pale of transynd for $158.
The only real way to do this is to drop the pan. even after fulling draining the pan, there still almost a gallon of fluid left in it lol. poor drain plug design.
Anyway, after pulling the pan, i performed the ~Allison~ fluid change method. Seems like Hoot is taking credit for it here, but the Allison service dept say the only way they change the fluid is basically what hoot described.
Just filled her back up with new filter, unplugged the cooler return line, ran a clear hose in a empty bucket, ran it untill a gallon was out, filled up a gallon, ran till it spit another gallon out....etc... stopped when i got clean fluid, topped it off and voila!
Does shift firmer, hope its $150 good though.
Also put synthetic fluid in my diffs and M1 in my T case.

I didn't see the posts regarding the enginie oil until after my switch. I had a devil of a time before my switch getting good info regards putting the transynd in the T/C and finally talked to an older mechanic at one of the largest dealerships around here. He is known for building cases for some of the 4wheelers around here and said that the transynd was a good choice.
Since seeing the info regarding using engine oil I am just about ready to at least add a quart of synthetic 0w-30 or 5w-30 to the transynd already in the case.
I bought it from the allison dealer near my home. You should be able to find a dealer close to you through the Allison web page. If you get the deep pan be sure to get the internal filter that goes with it.
There are three or four in the Indianapolis area, and one in Lebanon Indiana.
There is no aftermarket recommendation for transfer case fluid and GM only recommends the "Blue" GM transfer case oil, not ATF DexIII! Amsoil makes a great aftermarket,Synthetic oil for the new Allisons, called Torque Drive ATF.

Look in your owners manual, you will see that the "autotrak" transfer cases take the "blue" oil, but the manual transfer case that is the only T-case offered in the HDs takes "ATF dexIII"
But dont take my word for it, read the book
Im sure the reason is because the Autotrak T-case has the option of full time AWD or at least automatic 4wd. That means there is a viscus coupling in there that requires the special fluid.
