  1. Guessing you ment to say: now it “WON”T” shift out of park.

    In this case the mose appearant reason would be the shift linkage. With the engine off and the wheel blocked. Disconnect the linkage at the transmission and try to shift it manually, if it works fine, then concentrate on your shifter and linkage to locate the exact issue. Like you saud, the transmission worked fine in the other vehicle…..
