1992 Honda Accord Turns over but won't start after transmission rebuild

I have 92 accord ex. Just did a transmission rebuild. Now it won't start. What I have done this far to remedy: checked for fuel, spark, and compression. ALL GOOD. Replaced igniton coil. Replaced distributor o-ring. Replaced ECU. Waiting on the TCU. Checked all fuses and relays. ALL GOOD. Checked all grounds. GOOD. The only other issue I am having is that the transmission seems to be stuck in park or gear. It will not roll in neutral. I need help if someone has any thoughts. I am trying to avoid dropping the transmission again.
