[How to turn off converter lock up for certain gears ZF]

occurred to me it may part of a TCC partial lock strategy viz. Light, Medium, Hard   still not 100% sure though & havn't verified.                                                                          

Not sure if the the ZF runs it,  but common these days to see TCC partial lock (e.g. controlled approx 50 rpm TCC slip)  - helps keep the fuel economy benefits right down at low rpm , but the slip isolates out otherwise annoying driveline booms & vibe disturbances  - above certain rpm then can transition to full TCC lock  etc..

Regarding those 5 ZF Converter Schedule Tables (e.g. ZF03885 Converter Schedule 2 Manual Shift Mode) I wonder if someone can help as to the meaning of the three columns for each gear, L, M & H  ?
