I have a problem with my 700r4. The problem is that it doesn't shift at the correct rpm. It doesn't slip at all though. No matter where I have the kickdown cable adjusted. I took the valve body off and looked at it. Everything seemed fine. I noticed that the valve that connects to the kickdown cable has alot of play. Also the fluid isn't burned. Any help would be great. I kind of don't want to rebuild it if it is an easy fix. Thanks Year of tranny is 1992.
