Right now, your trans is the last of my problems, if your main ecu fuse is blowing as you wrote it is, this truck is going nowhere, so plz confirm your own writing and lets not focus on second third whatever trans right now. Get your head out of trans mode, focus on electric. regroup, and post back you understand

THE ONLY THINK I HAVENT TOUCH OR CHANGE IS THE TRANMISSION RELAY. SINCE IT HAD CABLES BURN A LITTILE AM THINKING IT MIGHTED SHORTED THE RELAY AND IS NOT SENDING A SIGNAL TO THE TRANMISSION

Let me try to explain, you have inadvertently created a short in the bus/can line and this is causing a no go to ECM, YES or no?

Here is a diagram of the data line.

I am going to be brutally honest, if TCM aint talking to ECM/PCM, that tranny is the second of my worries right now, is main PCM fuse still blowing? How many have you tried before you get to a point blank guy like me?

dont be sorry, just focus on main problem, your trans we wil deal with later, your main goal here now is to establish communication with pcm, cuz it NEEDS to talk to TCM, do you understand this concept?
