Problems with the valve body in your 4EAT trans. Valve body is replaceable, from the junkyard, though some yards won't let you pull just the valve body. Done plenty of these: crossmember needs to come off after car is in air, etc. Downshift cable is a pain, but doable. BEST to install a transgo shift kit if you are a mechanical whiz -- tightens shifts, takes out slop, removes the harsh shifting, etc.
BE warned though! If you pull the valve body from your car, sometimes the gasket between it and the case tears or falls apart. Then you need to buy the gasket rebuild kit ($150 plus) Best to just get another trans from the junkyard. Installation is a bear -- the first one is a rough one, but I've replaced about 20 of these transmissions, and with patience you can do it. You need a bunch of tools, trans jack, torque wrenches, patience, etc. Your trans problem is kind of rare, but your valve body is done. Good luck.
