This linkage is shown in our parts diagrams section. It is also recommended that you replace all the bushings documented in the following sections. When you buy your transmission, try to make sure that it shifts well. I know that this is very difficult, as most transmissions are pulled from non-running cars. Wear on this bushing will lead to sloppy shifting.
Replacement is relatively simple.
You need to remove the tapered screws all the way as they are not normal set screws. Separating the rear linkage bar from the front may require some tugging as the fit is sometimes quite tight. Be sure to use the correct hex wrench to remove the tapered screws. Once you have the rear bar removed from the front, the shift rod head should simply slide off. Remove the ball cup bushing, and then 'snap on' another one.
