Found some interesting info on hptuners forum from Robert at Transgo...
"As for making it not slip the converter clutch in 5th and 6th that's mostly only good for aftermarket converter that don't use the GM woven carbon lining and so prone to shudder. The carbon woven lining is very brittle and designed to slip without wearing out, but it is super brittle . the extra pressure required to make it not slip and the increase rate of apply is ******* it and it often will crack and lose chunks of it causing the TCC to start slipping after many thousandths of mile with this modification. Eliminating lock up in 1-2-3-4 is not going to hurt anything, but I would not recommend increasing the pressure to stop it from slipping the 20 or so RPM factory programing does."
