Did you try disconnecting the brake light switch yet? Could be some issue with the check control unit that enables engine braking while slowing down however it shouldn't have anything to do with the 1-2 upshift.

It must be valve body related. Old sloppy valve body gives me a good 2-1 downshift. Completely overhauled valve body gives me a bad 2-1 downshift.
