I have an 02 cavalier with the 2200 in it.The other day I was coming home from work stoped got gas and went to leave.I noticed my car was not shifting out of first so I had to manuel shift it all the way home.When I shift it manually it was really rough slamming into gears really hard.I ran the obd2 and it cam up with the shift silinoids a&b.Also came up with a p1680 code.I asked around and 99% of the people told me it was my PCM.If I go to the junkyard and pull one does anyone know how to get aroud the security?
