If its falling out if third you are losing pressure somewhere, probably in the 1-2-3-4/3-5-R drum.. I will see if i can find anything where the trans would act or apply something different in 4wd than 2wd, but there shouldnt be... Which transfer case do you have? The manual shift, auto, or the electric shift?

I have no idea never bin on a dyno , not big power tho nothing compared to turbo trucks and this 5.3 was low on power to begin with. im guessing 500 crank?? 0-60 4.5s ,1/4 13.5 at 110mph at 6800 alltitude i think what really slows it down is the gears and the big wheels , it felt fast the first couple lf weeks now it just feels slow

I had slipping issues turned out to be the check ***** in the valve body. Got an updated valve body and put metal check *****. No more issues the. The solenoid she started failing so new Tim and tune and haven't had anymore issues. I just put a 408 in my escalade with a 3k stall and I love the way it shifts.
Is your fluid real black?

Black fluid is normal, from the reaction with the clutches and coating on internal parts...so long as it isnt burnt.... Gm has a disclaimer in all the 6l80 info in si.. And there is also a tsb on it, i believe
I would do torlon checkballs not metal in the 6l80/90 they valve bodies and separator plates are too damn soft
