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.
