I am working on a 1973 727 trans and had to replace the reaction shaft bushing. After I installed the new bushing the input shaft will not fit into it as it is too tight. I removed and replaced it again just in case I tweaked it on install. The Shaft still does not fit. Do these need to be honed after install? Or are the new bushings (Federal-Mogul) not the right size. Bushing fits over the shaft ok with free play before install. Any help appreciated.
