Converter problem (New Thread) Question on lock up

MY converter slowly stopped locking up and has not locked up for a month, So I replaced the converter last night thinking I was now King. The converter still will not lock up. It worked 1 time for 5 seconds then unlocked after I pulled my tuning and went to stock then put tunes back in. I pulled codes of
P0743
P0603
P0741.
What is the next step, I need to hit the Florida hwy here soon.

P0743 is TCC circuit failure or open. You need to trace down and check your wiring (tcc circuit) and see if you have something wrong there.
