Zero fuel pressure at the rail.

No spark/no fuel = No start.
If you have no pressure, then you'll have to re check all your connections under the truck, make sure you didnt pinch any wiring when you were installing the transmission. Having the battery disconnected for a long period will not hamper it starting once reconnected.
No SES light is an indication something not cennected or is shorting. Check your underhood fuses for ignition and PCM.
