Re: gear hunting 2nd-3rd gear th400
Shift points are normally controlled by governor , but being highly modified , other things may be in play here.
I would find a 350 governor, put a 400 drive gear on it and try it with no mods.( 350 gov. has more windows for fluid flow to center spool valve.)
If nothing changes , back to valve body. Its not a pump issue
