I have a 93 pontiac Grand-Am v6 auto transmisstion..The problem I am
having is..before the car warms up it will go into reverse and drive (I
have only backed it up a little and then forward), but after it warms
up it will go in reverse but when I shift into drive or the lower gears
it will not move and the transmission will make a terrible noise.  The
fluid was checked and is a 1/2 quart low.  When it first started when I
put it into gear the car would die but if I gave it a little gas it
wouldn't die and it would drive normal.
Please any help would be great.  Thanks
Dawn
