Well I ordered the superseded number of what the manual recommends. 10-4016. 4qts. Also ordered the bracket for the tranny cooler. Need the cooler and maybe lines. Need to check the lines.

Nice!! You have a tune yet..?
Yes, I do my own installs and tuning. BTR stage 1 truck cam, Kooks 1 7/8, PRC ported heads, afe intake. Took about 1 second off the 0-60. It was unbearable to drive stock with the 5.3, it at least has some decent power now. What's interesting is the AFE intake threw the tune off more than any of the other mods. It made it go lean by 15%. Probably from moving the maf.
If I still have it in a few years, I will throw the 6.2 in, but this is fine for now.

Installed Arnott 2708 rear air shocks. Oem were blown bags.
Found my front sway bar links were gone. Rusted, etc
Installed links meant for a safari van. Seemed right size- they were in the parts bin. They fit and front bite is waay better.

Mechanic said front hubs will eventually need replacing. I could not detect any looseness, but he is the pro. He has an 08 Denali XL....
