Unbolt it from the engine, drop it down, and carefully unplug it.
Clean it up with a rag and alcohol or gentle solvent, and relube it with dielectric grease before you plug it into the new sensor, and reinstall in the reverse order you took it off.
You will probably need a small mirror to see the alignment marks properly; they need to be perfect.
If your speedo is off, this is a perfect time to change out the gear in the side of the tranny.
