A quick follow up to the rear motor mount install. This was a much quicker and straight forward job. Roughly 2 hours, maybe less if you have proper tools and know exactly what you're doing. Surprisingly, this made the most difference in clunking and hard shifting feel. This job completely rid of the clunking feel when suddenly letting go of the gas pedal at highway speeds. The transmission shifts were very smooth to begin with, and this job still made a significant difference. We highly recommend doing this since its a very easy job and the parts are also cheap.
