So I guess you ordered one tim! SUT?? Grey?? Adventure? Porno red interior?

When I ordered my 06, they did not tell me the mirrors and dash indicator had changed, and no one seemed to know about the changes until the 06's started showing up, so maybe they will just have the HID!!!! (Wishful thinking, right).

I ordered the H2 SUV with the removeable hard top. It will be the desert green cactus needle color with orange sage interior.

It should be porntastic~!

new six-speed Hydra-Matic 6L80 RWD electronically controlled automatic transmission backs the 6.2L engine. The six-speed automatic has a wide, 6.04:1 overall ratio – including two overdrive gears – that helps deliver an excellent balance of performance and fuel economy. Also, the 6L80 has a "tap up/tap down" capability that allows the driver to manually select upshifts and downshifts with a button on the column shifter. The new powertrain combination helps the 2008 H2 and H2 SUT deliver an additional 1,500 pounds (680 kg) in towing capacity – an increase from 6,500 pounds (2,948 kg) to 8,000 pounds (3,629 kg). A host of additional powertrain revisions also contributes to the H2's improved performance and efficiency, including:

• Larger-capacity cooling system complements larger, more powerful engine
• Electric engine cooling fans reduce "drag" on engine, enabling more horsepower
• Regulated voltage control maximizes fuel economy by charging electrical components only when necessary
• New LAN electrical architecture is more efficient and uses less electrical energy
• Standard 3.73 rear axle ratio

This does talk about the tap up/ tap down feature for the "M" on teh shifter.

But WTF is with the 3.73 rear axle?

6l80e gears:

First: 4.02
Second: 2.36
Third: 1.53
Fourth: 1.15
Fifth: 0.85
Sixth: 0.67

4l60e/4l65e gears:

First: 3.06
Second: 1.63
Third: 1.0
Fourth/OD: 0.7

Interesting, no true 1.0 gear, thour fourth is very, very close. With the drop in rear gear ratio with the new trans, it would seem as you are still achieving a lower cruise rpm per same mph with the new trans however, not enough to possible overheat the trans/drivetrain.

Also, went through a different set of gear/mph calculators. At 2000rpm, the est. mph in our current truck is about 72ish mph with an est. 35" tire, 4.11 rear and a fourth/od of .7. Now, at 2000rpm with the new setup, est. 35" tire, 3.73 rear with the sixth .67 ratio, that bumps it up to about 83mph.

So, your increase cruise speed at a given rpm, however, there MIGHT be a bit more strain on the trans though since it has more gears, it can more evenly spread the load instead of just 4 gears with the original 4l65e.

I really like the new powertrain of the 08. Finally GM is getting to something interesting... however, im not to sure on the interior, but i have to see one in person.

Hey guys new member here!

Currently I own 5 H2's, 4 are 25 passenger limos and previously owned an H1 before the H2's came out.

These upgrades for the H2 are the biggest news ever.

Even if it only gets 2 MPG thats an increase of 15-20%, that means buying 20% less gas! Thats alot. 3 mpg would be 25-30%.

Nobodys excited of an increase of 75 horsepower before any mods? And when cruising getting 25% better gas economy, come on! You guys are crazy!!!

Rear vents and extra stuff are good too.

Ive been calling my dealer they tell me they dont have pricing on the 08's yet, they have some ordered for stock of the lot but not pricing so you can custom order exactly what options you want.

I really hope they have HID lights, how can they not offer this in a $60k+ truck? The escalades are pretty close to the same price and have them standard!
