Hate to tell all, but a few weeks ago this popped up in the tech section, and I confirmed with the engineer in charge of axles, and there is only ONE axle ratio offered on the 2006 H3 Hummer; and that is 4.56:1.
This is irregardless of what a marketing sheet has on it. Prior to calling, I had pulled vehicle information build sheets for autos, manuals with and without the off-road package, and found only 4.56 gear listed. </div></BLOCKQUOTE>
Interesting on the auto vs. manual rear end ratio.
1. A little suspect though, since we are hearing that gearing in 5th gear on the manual tranny is considerably taller than 4th on the auto tranny. Based on the chart above 5th gear should be slightly lower given that rear end ratios are the same.
2. It's very normal for auto and manual setups to have different final drive ratios.
The engineer might be a little drowsy. Nudge him to recheck.

I should keep out, but I won't. The engineer in question is the head service engineer for this part, he is a manager, he is also in charge of the release of this part to service application. He assured me it was a 4:55:1 gear, and this went right along with all the vehicle history build sheets I pulled up in the system.
In my opinion, I don't need to nudge him. Maybe those with all their innuendos and assumptions should get nudged a bit.
