When does the 6L80's torque converter clutch apply, and how does tow/haul mode change the shift pattern?

Here is what the documentation says. Each point links to its source; tables and names vary by computer, operating system and tuning software.

• Terminator X Max; LM7, LQ4, LQ9, LS3; 2007+: TCM torque requests can occur during upshifts, downshifts, and torque converter clutch events. Torque Converter Clutch Lock/Unlock during shift tables define whether the TCC stays applied across shifts for each gear change (1-2 through 5-6), in both normal and cruise modes. (Holley)
• P01, P59, E38, E67; LM7, LQ4, LQ9, LS1, LS2, LS3; 1999-2013: HP Tuners' TCC Lock During Shift parameter controls whether the converter clutch stays applied across a gearshift; enabling lock-through-shift is described as extremely hard on the transmission and TCC. (HP Tuners)
• P01, P59, E38, E67; LM7, LQ4, LQ9, LS1, LS2, LS3; 1999-2013: HP Tuners provides separate TCC apply/release speed tables for Normal, Cruise, Performance, Hot, 4WD Low, and Tap Up/Tap Down modes, plus dedicated WOT apply/release schedules; the apply/release tables are indexed by TPS and gear.
