You probably messed up the front pump then, since torque converter wasn't detached.
It is a big deal since full rebuild is needed to get to front pump.
How did it go back together?
easy, just slid back into place
or did you have to use the bolts to snug up(force) trans to engine
Look at the pictures of torque converters seen here: http://www.hotrod.com/how-to/transmi...ue-converters/
You will see the two slots, 1 to 2 inches deep, they drive the front pump, which has two "tabs" that need to line up with the slots, if they are not lined up you can still bolt the trans to engine but it won't slide in easy and flush, you will have to tighten bolts to get trans flush with engine, than that breaks the front pump "tabs".
I assume you didn't disconnect the wiring on trans, you could check that both sides are hooked up
