I have a Trango Jr. Shift kit that has been lying around awhile and am looking at installing it. The question I have is that the green spring that comes in the kit for the PR Valve is missing. Also from what I remember the TV Boost Valve doesn't come with that kit. So should I still go through the trouble of installing this? Should I go get another Jr. Kit? What would the result be if I did this kit along with the B&M shift improver kit? I have read that nobody thinks the B&M kit should be installed in the 700r4. I know that I had a B&M kit in a previous car and I loved the shifts. The car has a ton of overlap between 2-3 and 3-4.
