LML Converter lockup

[btfarm]

The Allison 6 speed on my LBZ always locked in 5th and unlocked in 2nd under normal driving conditions. Now, with the LML I'm unsure what those points are. I have heard lock was in 3rd. Seems odd to me. Keep in mind, in my instance, Wherli has changed the trans tune when they did the CP3 conversion.

Playing around with it some it appears it is still a 5th gear lock and unlock is dependent on grade braking and/or tow haul settings. With my tune it locks a bit higher speed than standard.
