4R100 program...TCC

Hey y'all, just wanted to see if this is normal,
My 2000 F350's 4R100 will not lock
up the TC when the engine is below operating temp. Seems like it makes sense, but wasn't sure if that's how it's programmed?

Yes, that's how it's programmed. Both the engine and trans have to reach certain thresholds in order for the converter to lock.
