The first thing you must do to begin to address any shifting issues with this tranny is to get rid of the spongy oem bushing in your garbage shift bracket. The urethane Energy Suspension 16 dollar bushing is light years ahead of the stock piece. It helped almost as much as my Barton 2 post bracket did.
