SM = System malfunction
22= Clutch Actuator
Here is the link for the freedom line transmissions:

Pull inspection plate on bottom of trans, look and see if the clutch actuator has disengaged the clutch. Mine had the same codes, turned out my throwout bearing came apart and you could see the inner race in front of the throwout bearing.
