Turbo 400

OK this is what happened. Getting ready to pull the engine for rebuild I drained the trans pan. After the rebuild hooked the trans back up and installed in the truck. I had bought a new trans pan and at this time decided to put it on. Expected the old pan to be empty when I was taking it off. It was not! Apparently when pulling and reinstalling the engine I had enough slat to I am thinking drain the torque converter. Do I run the risk of hurting the trans or tc on start up?

No it will not. put about five qts in trans start engine and check it.

Thanks for the reply!
