fluids for the transfer case

does anybody know what kind of fluid does the transfer case take and the rearend and front transaxle for a 1997 K 1500 5.7 L 4X4 six lug Z-71

You can use any 80w-90 gear oil for the rearend and front differential. Pretty sure you can use the same in the transfer case. A buddy of mine uses synthetic and claims he never has to touch it again.

On my 90 K1500, the transfer case uses Dextron-III tranny fluid. My 2000 Yukon takes Auto-Trak Fluid.

I am pretty sure it takes Dextron-III for the transfer case on a 97.

Use Dextron in the T/C. 80W-90 is fine for the frontend and rearend but NOT that transfer case. Add limited slip additive if you have one in the rear.

right right nice truck looks like mine my truck is teal green. i want to put hood scoops on it but did not know what it wound look like but now i know. nice.....
thanks everybody.

the reason i wanted to know is i thought about witching over to amsoil synthetic on everything anybody heard anything about them

I've used their oil in my wifes Neon for a while now. Its great stuff. The car always had some lifter noise on startup until the oil warmed up ( all neons do). I put this stuff in along with their filter, while it was about 30F outside. Started it up and was completely quiet ever since. Havent tried their tranny fluid yet, but i feel real confident now about their stuff.

Transfer case use ONLY ATF fluid Dextron 3 , the front and rear diffs you can use gear oil
