"Trans L" torque management source?

I'm familiar with "Trans S" torque management source (reported by "Immediate Engine Tq Src" PID), but I recently started noticing "Trans L" listed in that PID from time to time in my logs, but I can't seem to find a description of what it means. I'm guessing it's "Trans Limit"? If so, what exactly does that mean and how can I tune it out if desired?

E39, T43 ECM/TCM.

Thank you!

Bump. Been noticing this more and more, typically when reapplying throttle after coasting - I have NO IDEA what this is telling me or what I can "tune" to eliminate it (it pulls a LOT of timing when it occures).

Anyone have any insight as to why I'm getting this particular type of torque management and how to limit it?

Thank you!
