Engine started to have a miss.Throwing bad maf code.Replaced maf then bad plugs&coils code so replaced them.Then transmission failure lit up&truck died.That led to blown 33 fuse every time i cranked it.Started throwing to many codes to list so replaced pcm.Installed refurbished preprogrammed pcm from liable source.It came with 2 programmed for vin# blank keys.Had keys cut from original.Truck fired right up so test drove&made it couple miles before transmission failure popped up then died.Put new fuse in 33 hole and got it started.Put scanner on it and it shot 40codes.Same as before new pcm.Almost all codes are electrical,could new pcm have failed.Ive spent Couple grand to no avail.Any advice i appreciate

 

Highly unlikely the PCM was ever the problem.
Fuse 33 burning up repeatedly is the clue.
I'd guess there are some wires melted onto the exhaust or chafed near the corner of the engine. Fuse 33 supplies voltage to the rear or sensors and some of the transmission sensors.
The other side of the circuit to the 02 sensors (grey-red 359 circuit) is common to the mass air sensor as well, so melted wires that are common to those two circuits would explain fuse blowing and lots of drivability or possibly dtc problems.

 

Fuse 33 powers

• Heated Oxygen Sensor (HO2S) #12
• Heated Oxygen Sensor (HO2S) #22
• 4R75E transmission
• Ignition Coils (all)
• Ignition Transformer Capacitor (both)

From the above its easy to see why the truck stalls when the fuse blows.
​​​​​​​I would start by inspecting the wiring to the downstream O2 sensors. You may have a burned or chafed wire.

 

This is a good read on Fuse 33 -
