My buddy has a 97 buick park ave ultra with the supercharged 3.8 and it won't move. If you put it in gear you can feel it shift but it won't move. Doesnt matter if it's in 1st or drive,pedal to the floor and all it still wont budge. Trans never slipped while shifting and only shifted hard a few times when it was a little above operating temp. I'm stumped boys,any of yall had this problem before? Could it just be something simple like being low on fluid or a solenoid? Thanks guys
