The first thing you will want to do is remove all of the major components from the gearbox.

For this guide, the wiring and selector plate will be removed just to make things easier.

You DO NOT have remove the bushings if you don't intend on replacing them. There is no harm in doing so, but it would just be extra work.

If you have not done so already, now is a good time to clean your gearbox. The safest and most effective way to do this is by using electrical cleaner or silicone spray along with a clean rag.
