As long as you can turn the torque conv. with a screwdriver underneath the car at the square opening of the bell housing then the pump and installation should be OK.
All the conv. bolts made it back in?
I have run into rare cases where the fresh fluid from refilling a trans killed it after draining the old fluid for whatever reason.
ATF has a high detergent effect to it.
On borderline trans' this can be enough to put a worn clutch pack over the edge or a seal that was hanging on by a thread from the junk in the old fluid.
Was the old fluid burnt or very dark in color?
Is the kick down cable in the right place and did it get yanked for any accidental reason?
If the manual valve got jammed in the wrong place while during R&R I could see this happening too.
Slowly pull the kickdown cable after removing it from the throttle housing to feel for a change in the tension of the cable.
If there is some strange slack the manual valve inside the trans might be jammed or stuck in the wrong spot.
You would only have to drop the pan again to see if this has happened.
