On the original was the fluid changed according the schedule in the manual? As I recall it's every 30k. If not, that could have toasted it. Since you got 2 used replacements, you have no idea when those one was changed. GM 4WD systems are very temperamental when fluid isn't changed regularly.
I agree with the others, this is more likely a gearing difference.
