Talk to these guys about tranny upgrades that they have proven will last using it in other rides and for a good time now. They are:

flp2win.com

700raptor.com

I have talked to both shops several times and both seem eager to do what they can to please and meet your needs.

One thing to keep in mind when talking about tranny upgrades is to remember that 03 and 04 tranny's came with a 4 gear and sun cage. They will upgrade you to a 5 gear and hardened sun cage.

On the 05 and up the tranny was switched to 5 gear and sun cage by factory so some gain there. The only advantage is if the newer parts have been cryoed.

In either case they if I remember correctly then add in a hardened input shaft. So main thing is ask how they have improved over the stock tranny you have and if in certain areas the factory has already made that upgrade can you save money by not having to buy these parts in a rebuild.

Now if You buy a swap out then you are stuck paying for things that you had already upgraded possibly in your factory tranny.

Well not much help but, at least some places to talk that will ship to you.

Oh on putting a 4l80 tranny in H2 is that when the tail shaft is turned down it weakens it and you may as well have run an upgraded 4l65e. I have asked questions of shops and they tell me that the turned down 4l80 shaft or even the 4l65e shaft could be croyed to make them extremely heavy duty. We are having rotors on brakes cryoed so that they almost do not wear out.

Hope this helps some on getting on the right road to get what you need.
