My th400 would go in gear but only after 10 min of warming up my dip stick had air bubble on it as well i took the pan off and changed to filter i also added a spacer to hold the filter close to the valve body it fixed the problem im not sure it would fix urs u may have changed it when u did the pump

So you broke the pump during installation and replaced the pump and converter. Did you reinstall the pickup tube and filter? Is the manual valve connected?

Pick up tube and filter are in there good not sure what you mean by the manual valve though? Could you Direct me too it?

The transmission shift linkage operates the manual valve in the valve body. You may not have connected it.
