What's the question?

 

[Gametrap]

Ideas on what would cause not having overdrive

 

[Powerstroke Cowboy]

What are the symptoms? Does it try to shift into OD? If it does not even try to shift, there's a good chance you have a bad shift solenoid.

Has a new shift solenoid in it, just want go into 4rth all other gears shift great tc locks like it's supposed to just no 4rth gear

Was the transmission working properly after the rebuild? The shift solenoids control the shift. If it's not the solenoids then it's wiring.

No it has lost overdrive that's why it was rebuilt
Everything shifts fine up to overdrive

 

[ncollins64]

Ok just to clear it all up, you lost overdrive, had the trans rebuilt and ever since the rebuild it shifts and runs perfect up to overdrive and then doesn’t shift into od?

 

[Gametrap]

Correct

 

[Tiha]

Did you replace the overdrive sprag when you were in there?

What codes are stored in the PCM? If it won't shift to overdrive it WILL set at least one code.
