my sister has a 96 gs and she had a problem with the automatic transmission not shifting out of second and it was also slipping really bad. i checked the fluid level and it was low so i put enough in and now it doesnt slip at all..so the only problem now is that it wont shift out of 2nd. even with high rpms it still doesnt shift. i took it to the transmission shop and they said it was maybe the computer and not the tranny, or something electrical..any ideas on what it could be? anyone else had this problem? thanx
