Need more info about this "tranny will not shift"? What do you mean? Wont mechanically shift into (D) or goes into gear but wont shift past 1st gear? Does manual 1 or 2 work? Did you get your shift cable properly attached to tranny and not get the adjustment out of wack at its adjuster?

Mechanically appears to shift but the transmission doesn't engage in any gear. Will check speed sensor and shift cable.
