Thank you all, especially Mr. Dalton. The bad transmission is out and the replacement is in. However, now I have a new issue! The engine will turn over and actually tries to fire, but won't continue to run. I've checked and rechecked all of my electrical and vacuum connections and they are secure. It must be something that occurred during the transmission swap because the car was starting and running great the day that we removed it. Any ideas on where to start looking?
