I don't think the cvt has a locking torque converter, even in "manual" mode because it still drifts a little bit. Supposedly the final drive ratio in high gear is 2.11:1, (0.570:1 high gear and 3.70:1 diffs) and in the manual xmission it's 3.03:1 (0.738:1 high gear and 4.11:1 diffs).

However, in 6th gear (about the same as loping along in Drive) at 70 mph mine is turning 2200 vs. 1980 rpm, which seems to indicate the cvt also has 4.11 diffs and that spec sheet is wrong. I don't have a service manual yet so I don't know what that says. If the gearing is correct for the 5 speed it would be turning about 2850 rpm at 70 in 5th. With the cvt in "5th" and manual it's turning about 3150 rpm at 70.
