I was worried about that gear jump from first to second in a 700 as well. Sometimes I notice it in the SS, which has 4.10 gears, less weight and twice the usable power of that tired 6.2. I would think that the large jump would be even more pronounced with this diesel because you only have about 2,000 rpm of usable range, vs about 4,000 in a gas v8. I wouldn't be suprised if the burb had 3.55 or even higher (numerically lower) based on how fast i've "cruised" down the interstate. It's hard to tell with out a tach or just opening up the diff though.
