sometimes tranny gets stuck within the synchros...start it, and get a couple of buddies to shake the crap out of it from the outside, pushing the car back and forth. had this same issue with a 1990 dodge shadow...once you get it out of park, and you need it to stay put, leave it in neutral and use the parking brake. btw the 1991 626 is a great car, i had one with a manual though...450'000 kms on her before she died...
