2000 ford taurus- wont shift into gear
first check drive axels , since you replaced front springs on struts i assume. it is possible that one of the axels popped out. next if thats ok check fluid level in trans with eng OFF should show over full make a srcribe mark on the stick. then START the eng it should go down to full or just below depends if trans is full or a little low . if level does not drop approx.1/2 in or so then have a transmission shop check for bad splines in torque convertor, that is a comon problem in that car, year and milage do not play a roll a large roll in parts failure in trans any more. not like it use-to.
