I am about to pull my 289 out of my 1967 Mustang, and I am going to separate my 4 speed top loader transmission and mount the engine on a stand for a bit. While they are separated I want to open up my transmission and see if it needs any rebuilding. Does anyone know of a good step by step guide for rebuilding and assembly/disassembly of a Ford 4 speed top loader transmission? I have found a few general transmission guides, and some that cover transmissions built by GM, Chrysler and Ford all in one book. I am looking for one that is specific to my transmission. Thanks.
