That doesn't always give the desired response. Go with GM #8673948.

I just installed the GM kit and I like the results. I even posted the results here in this section(topic). The GM one will still allow a downshift to third at lower speeds but at highway speeds it stays in fourth unless you manually downshift it to third. I actually have 4 gears that I can use whenever I want to!

By the way the B&M one is not worth your 35$!
