My SD isn't shifting right either. I only expect to fix it when I am willing and ready to go through the process of making sure that all control systems are set up correctly. Right now, I don't have a working pressure gauge so it ain't gonna happen.

Just guessing at various pressure and turning things doesn't work. Professor google turns up lots of how to's and service manuals for various iterations of the 722.xx trans. IF you have correct vacuum AND fluid pressures in the tranny, you can go through the process.

My understanding is that most flares & hard shifting are vacuum & pressure induced or at least can be adjusted away - but not all. One can't determine that hard parts are needed without knowing that the external systems are working.

My attempt at guessing instead of measuring was akin to urinating off the high side of a sailboat.

Here are a couple of links.
