Sticky Shifter
not hard at all just make sure it all goes back together in the same order it came apart
one thing I like to do when re assembling every thing is to flip the bushing that the shift levers ride on end for end, over time the shift levers wear groves in the bushing on one end, just reverse it and put it back so the good end is where the shift levers ride, that will remove a lot of the excess play, combined with a good cleaning and new grease it will feel like a new shifter
