My car wont start :-( on 2000 Honda Civic

i recently replaced my transmission, and my car was running ok, then on my way home my car just cut off. I put the car in park and tried to restart it but it wont start. the check engine light and the green square light around the D comes on for a couple secs then cuts off. and this happens everytime i tried to start it. what's wrong?

I feel like you may have some wiring issue related to the switch that tells what gear your lever is in. Either a connector that is not fully seated or a pinched wire from the transmission installation. Recheck the installation and all the switches and wiring first.
