Glad to hear you got it together and its working good for you! Also good to hear someone that has the torsen diff and and how it is working. The Transgo shift kit is not a performance kit and the shifts arent going to be much firmer than stock unless you make changes. The Wbody store shift kit uses spacers to limit/block accumulator travel which gives you higher pressure during a shift. The transgo kit is a progressive spring setup that will give higher pressure sooner than a stock spring but not as much as just using longer spacers.
