when replacing transmission on a 2000 chevy silverado 1500 will the tranny go together if the torque convertor or fly wheel is in wrong

there is only one way to install the flywheel, the torque convertor should be slid onto the transmission shaft then the transmission should be hoisted into the truck and bolted to the back of the block. then you attached the convertor bolts to the flywheel afterwards. basically there is only one way this assy can go in - hope this helps
