The Sport Auto only uses the torque converter in first gear.

I have read the same thing. But I also believe the 2008 Steptronic is the same basic transmission, just with less agressive shifting, etc. See ZF Auto Tran but the article doesn't go into the details of the Sport Auto version.

Also, I think Lexus is using similar technology / logic in the 8-speed transmission in the IS-F
