Back to H2 bashing.  I found out those things come with a 4L65.  I thought since it have bigger axles and the 6.0 they would use the 4L80.  Then they suck even more.  4L60/4L65 trannys are worthless in such a heavy vehicle that should be used for towing.  It has 3/4 size axles but not the tranny.  That's funny because if they went to the 4L80 I bet MPG would suffer even more, but at least the tranny is stronger.
