The factory TC locks just fine. There is nothing wrong with the TC in a 2001... There is an issue with the mechanical diode on the 2001 my trans, but it has nothing to do with how the trans functions until it just up and dies.

Are you having somewhat the same symptoms with your truck? Which converter are you going with for your truck?
TC is not your issue.
You say you have pressure tested the IC, have you tested the entire system?
I would suspect a boost leak, but with the boost levels your hitting that might not be the case.
130k I doubt its an injector issue, but it could be bad or getting bad injector O rings.
When you checked the fuel pressure was it under load? How did you test it?
